Researchers at Houston Methodist have developed a biodegradable implant that can be used to safely and consistently deliver drug treatments to tumors and then dissolve without the need for further surgery.

The implant is only the size of a grain of rice, but its potential is staggering. The biodegradable nanofibrous drug-eluting seed (b-NDES) works as a reservoir parked inside a soft tumor, where it can slowly release immune-stimulating drugs over time. This overcomes a consistent problem with drugs such as immune checkpoint inhibitors. Normal systemic administration sees comparatively little of the drug making its way to the tumor, with most of it circulating throughout the body. The b-NDES is like deploying a small guerrilla fighting force embedded in enemy territory, doing maximum damage to the entrenched tumor.

"To improve cancer treatment, we're trying to start a fire inside the tumor itself," Corrine Chua, associate professor in the Center for BioNanoengineering at Houston Methodist Research Institute, said in a news release. "By activating immune cells directly within the tumor microenvironment, those cells can then travel throughout the body and seek out cancer wherever it exists. The b-NDES platform was developed to help keep therapeutic drugs concentrated inside tumors while minimizing exposure to healthy tissues.”

Chua co-led the study with Alessandro Grattoni, chair and director of the Center for BioNanoengineering at Houston Methodist Research Institute.

The study included support from the Nancy Owens Breast Cancer Foundation and the National Institutes of Health/National Cancer Institute.

Chau and Grattoni used preclinical models of triple-negative breast cancer, an aggressive form of cancer that is estrogen receptor-negative, progesterone receptor-negative and HER2-negative. Because of the receptor negativity, some popular treatments like tamoxifen and trastuzumab are ineffective. Chemotherapy has been shown to be the best course of action.

The b-NDES implant is deployed alongside radiation drugs. It keeps the drugs focused on the tumor, reducing the amount of harmful side effects typically seen when drugs are circulated more widely in the body. In 60 percent of the models, tumors were eliminated and did not cause side effects beyond the tumor site. Once the drugs have been deployed, the implant breaks down naturally.

While promising, more research will have to be done to expand use to other tumor types.

"Although the study focused on triple-negative breast cancer models, the approach could have broader applications for solid tumors," Grattoni added in the release. "It could potentially be used in cancers where there is a tumor lesion accessible for placement, including pancreatic or lung cancers."

These 3 Houston research projects are revolutionizing health science

Research roundup

Researchers across the world are coming up with innovative breakthroughs regarding the coronavirus, but Houston research institutions are also making health and wellness discoveries outside of COVID-19.

Here are three from Houston researchers from a muscular atrophy study from outer space to a research project that might allow blind patients to "see."

Houston Methodist researcher Alessandro Grattoni and his team published research on muscular atrophy in astronauts. The research was published in Advanced Therapeutics and focused on his 2017 RR-6 muscle atrophy study that was conducted on the International Space Station.

While the current standard practice for astronauts maintaining their muscles is working out over two hours a day, the research found that use of drugs could also help preserve muscles. On a SpaceX refuel mission, mice that were implanted with a "Nanofluidic Delivery System" were sent up to space and monitored, according to a report. The device gradually released small doses of formoterol, an FDA approved drug for use in bronchodilation that has also been shown to stimulate increased muscle mass.

University of Houston researchers are looking into the way the body responds to fear in order to enhance mental health treatment. Rose Faghih, assistant professor of electrical and computer engineering, and doctoral student Dilranjan Wickramasuriya in the Computational Medicine Lab (CML) are leading the project.

"We developed a mixed filter algorithm to continuously track a person's level of sympathetic nervous system activation using skin conductance and heart rate measurements," writes Faghih in the journal PLOS One. "This level of sympathetic activation is closely tied to what is known as emotional arousal or sympathetic arousal."

When this sympathetic nervous system is activated — sometimes known as the "fight or flight" response — the heart beats faster and more oxygen is delivered to the muscles, according to a press release. Then, the body begins to sweat in order to cool down.

"Using measurements of the variations in the conductivity of the skin and the rate at which the heart beats, and by developing mathematical models that govern these relationships, CML researchers have illustrated that the sympathetic nervous system's activation level can be tracked continuously," reports Faghih.

This algorithm could be used in a wearable electronic device that could be worn by a patient diagnosed with a fear or anxiety disorder.

Baylor College of Medicine's vision-restoring research

When someone loses their vision, it's likely due to damage to the eyes or optic nerve. However, the brain that interprets what they eyes sees, works perfectly fine. But researchers from Baylor College of Medicine have worked on a thesis that a device with a camera could be designed and implemented to do the seeing for the blind patient.

"When we used electrical stimulation to dynamically trace letters directly on patients' brains, they were able to 'see' the intended letter shapes and could correctly identify different letters," says Dr. Daniel Yoshor, professor and chair of neurosurgery in a press release. "They described seeing glowing spots or lines forming the letters, like skywriting."

Through a study supported by the National Eye Institute with both sighted and blind people using implanted devices, the investigators determined that the process was promising. According to the release, the researchers identified several obstacles must be overcome before this technology could be implemented in clinical practice.

"The primary visual cortex, where the electrodes were implanted, contains half a billion neurons. In this study we stimulated only a small fraction of these neurons with a handful of electrodes," says said Dr. Michael Beauchamp, professor and in neurosurgery, in the release.

"An important next step will be to work with neuroengineers to develop electrode arrays with thousands of electrodes, allowing us to stimulate more precisely. Together with new hardware, improved stimulation algorithms will help realize the dream of delivering useful visual information to blind people."

3 health technologies developed in Houston that are changing the industry

Game changers

There's a huge opportunity for breakthrough medical technology in Houston thanks in large part to major universities, the Texas Medical Center, and other resources within health care startups.

From a new tiny implant that can deliver medicine into the patient remotely to printable human tissue, here are three health technologies coming out of Houston innovators to look out for.

Houston Methodist nanomedicine researchers have developed an implant the size of a grape that can deliver medicine via a remote control. The device has applications in arthritis, diabetes, and heart disease treatment.

The battery-powered nanochannel deliver system uses Bluetooth technology and can dole out continuous, predetermined dosages for up to a year without refills. A proof-of-concept for the device published in Lab on a Chip.

"We see this universal drug implant as part of the future of health care innovation," says Alessandro Grattoni, chair of the nanomedicine department at Houston Methodist. "Some chronic disease drugs have the greatest benefit of delivery during overnight hours when it's inconvenient for patients to take oral medication. This device could vastly improve their disease management and prevent them from missing doses, simply with a medical professional overseeing their treatment remotely."

The devices can be programed for different dosage sizes and different release settings, which affect the voltage for the medicine delivery.

NurseDash's resourceful scheduling tool

Filling open nursing shifts has always been a challenge for hospitals and medical centers, and they've been forced to rely on outsourced companies to coordinate nurses to fill the shifts. NurseDash puts the power back in the hands of freelance nurses and the medical institutions that want to hire them.

Andy Chen, former CFO for Nobilis Health Corporation and co-founder of NurseDash, says the standard practice is hiring these agencies to fill shifts, and, while they promise to send someone, they don't even know who they'll be sending for a shift just hours away. This antiquated system prioritizes who comes in first, rather than a nurse's specialties or qualifications.

Since its debut, NurseDash, which is based in Houston's Galleria Area, has attracted 40 facilities in Houston, including hospitals, surgery centers, and senior living, and about 400 nurses. Chen says he isn't sure just what to call his technology yet, but compares it to the ride hailing of Uber or Lyft and calls it "a virtual bulletin board."

The company has already expanded beyond Houston to northeast Ohio, which the founders say has a similar competitive dynamic to the Houston market. The next goal is to hit the rest of the top 10 largest cities in the United States. To read more about the app and startup, click here.

Volumetric's human tissue-printing technology

In a world where organ transplants means an incredible amount of time, money, and patience, there might soon be another option on the operating table. Volumetric is a startup that came out of a human tissue-printing technology developed at Rice University.

Jordan Millar developed the 3D printer in his lab at Rice, and still has ongoing research within the technologies. However, Miller says he very strategically chose to launch a for-profit company in 2018 — mainly, to provide access.

"If we want to do translational research, commercialization is important," reasons Miller. "We need to build the market to get that technology into the world."

Right now, the device is printing scaled down organs, and a contraption that looks a bit like a futuristic beehive, graced the cover of the May 3 issue of the journal Science. It's a working air sac complete with blood vessels, the beginnings of a technology that is perhaps only a decade from being implanted in humans. To read more about Volumetric, click here.

New manufacturing facility breaks ground at NASA’s Johnson Space Center

making space

HITT Contracting has broken ground on NASA’s Applied Spaceflight Fabrication Facility (ASFF) at Johnson Space Center, the Washington, D.C.-based construction firm announced late last month.

The project, known as Building 70, will house a high-bay machine shop to support component production for future NASA space missions, according to HITT. The 37,625-square-foot building is the first part of a larger goal to create an engineering complex that unites assembly space, lab capabilities and manufacturing at JSC. It will consolidate machining equipment and operations that are currently spread across multiple campus buildings into one location.

The project broke ground in October at JSC’s Historic District. The Houston Business Journal reports construction is expected to wrap in August of 2028.

“This project will modernize facilities that support America’s space missions,” PJ Ross, chief financial officer at HITT, said in a LinkedIn post. “Proud of our team and partners as we begin construction that will advance aerospace testing and innovation.”

HITT Contracting is one of seven companies awarded infrastructure contracts by NASA earlier this year for work at JSC. According to NASA, the construction contracts “[support] up to $300 million in upgrades to mission‑support facilities, utilities, and equipment across the NASA Johnson campus.”

Construction Drive reports that HITT will also renovate Building 13 South on the JSC campus as part of the $300 million initiative.

“Building for precision manufacturing starts with understanding how the space needs to perform,” Todd Hudson, vice president at HITT Contracting, added in the release. “Our team brings the technical expertise and collaborative approach to deliver a facility that meets the Johnson Space Center’s needs today and supports the next generation of spaceflight innovation. We’re proud to continue our partnership with NASA.”

NASA also recently announced awards as part of its expanded Moon Base exploration, science and infrastructure capabilities. Houston-based Intuitive Machines and seven other spacetech companies, including SpaceX, Blue Origin and Firefly Aerospace, were selected to receive funding.

The awards are part of the next phase of NASA’s CLPS (Commercial Lunar Payload Services) initiative, which will grant the companies a combined total of up to $10 billion over 10 years.

Intuitive Machines and Webster-based MEI Technologies were also awarded contracts this past summer from NASA to develop robots for exploring the surface of Mars. Read more here.

meet the finalists

Houston’s thriving startup ecosystem is supported by a network of experienced leaders who work behind the scenes, investing their time and knowledge to help the next generation of entrepreneurs succeed.

As part of the 2026 Houston Innovation Awards, the Mentor of the Year category will honor an individual who dedicates their time and expertise to guide and support budding entrepreneurs. They support promising startups in the medical tech, digital health, clean energy, hardware sectors and more.

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Al Danto, Rice University

Al Danto is a senior lecturer in entrepreneurship at Rice University. He mentors undergraduate and graduate students at Rice and through the university's Liu Idea Lab for Innovation and Entrepreneurship (Lillie). He's also involved in the Houston Entrepreneurs Organization and Rice Veterans' Business Battle.

"[Mentoring] is very rewarding and fulfilling," Danto says. "[It] helps to me to pay back full circle over the incredible mentors I have had."

Eric Rubenstein, New Climate Ventures

Eric Rubenstein is managing partner at New Climate Ventures. He mentors startups through the clean energy-focused early-stage VC firm and also through the Breakthrough Energy Fellowship, Activate, Greentown Labs and Yale Ventures. Rubenstein has worked with numerous startups and Innovation Awards finalists, including Solidec, Rheom Materials, Bairitone Health, Pattern Materials and many others.

"Being a mentor is an important part of an innovation ecosystem," Rubenstein says. "Seeing founders succeed is rewarding, particularly if what they are building will meaningfully contribute to society. It is a way to give back that also builds community, as mentorship often involves introducing founders to other mentors, to potential investors and to potential customers. Just like the adage 'it takes a village' is used in reference to raising a child, the same adage applies to building a startup. That’s why we say 'let’s build.' Let’s build is inclusive because we do it together, as a community, even if the founders need to execute on a daily basis to make their vision a reality."

Jeremy Pitts, Activate

Jeremy Pitts serves as managing director of Activate Houston, which launched in Houston in 2024. He was one of the founders of Greentown Labs in the Boston area and served in a leadership role for the organization between 2011 and 2015. Through Activate, he has mentored numerous impactful startups and Innovation Awards finalists, including Solidec, Coflux Purification, Bairitone Health, Newfound Materials, Deep Anchor Solutions and others.

"Mentorship to me is all about selflessly supporting a person," Pitts says. "The person comes first--if you're not supporting the person, then their business needs don't matter. I'm there not to answer questions for people, but to help them gain the confidence and the capability to solve problems on their own. I am successful when my mentees are successful and happy, regardless of what their personal definition of success might look like."

Joe Alapat, Liongard

Joe Alapat founded and serves as chief strategy officer at Houston software company Liongard. He founded Startup Circle Houston and co-hosts Cybersecurity Circle, which both meet regularly at The Ion. He participates in Mercury Fund Day and has also mentored through Impact Hub Houston. He's worked with founders of FlowCare, Unytag, STEAM OnDemand, Lokum and many other early-stage startups.

"I compare being a mentor for startup founders to the Montessori method. ... Mentoring should not involve telling a founder what to do," Alapat says. "I see it as a founder whisperer approach that seeks to challenge the founder to think through their journey through different lenses and go on a journey of self-discovery while discovering the true market pain they are seeking to solve. The cherry on top is that the mentor gains as much as the mentee, so learning is happening for both. Ultimately, the meter of achievement with mentoring is seeing visible progress with the maturity of the founder and the degree of traction for their startup."

Kyle Judah, Rice University's Liu Idea Lab for Innovation & Entrepreneurship

Kyle Judah is the executive director of Lilie, where he mentors pre-seed student startups. He also mentors through organizations like TEX-E, Greentown Labs, Activate and previously with MassChallenge. Some of the startups he's mentored include Helix Earth Technologies, Tierra Climate, Solidec, HexaSpec, SteerBio and many others.

"[Being a mentor] means helping to ensure that the most people possible have the best shot possible at making their company a successful reality," Judah says. "It means, at its root, opening the aperture for what is possible for people, by believing in them before anyone else even understands what their ambitions are. Because belief is the most infectious thing in the world. And before digging into the work in the trenches, most times founders need to kickstart their journey by having someone from the outside believe in them, when there's no real evidence to support that belief. So I guess, mentorship is a pure form of entrepreneurial faith."

Rachel Bickham, Bickham Services Unlimited LLC

Rachel Bickham is CEO of Bickham Services Unlimited, through which she mentors founders across a range of business stages and industries. She founded the organization in 2017. Bickham also mentors through The Affirmed Entrepreneur, a mentorship platform that she also launched. In 2024, she also began mentoring through the Goldman Sachs One Million Black Women: Black in Business program. Some of the startups she has worked with included Elaine Transportation, Nakira's World and NP Skills Made Easy, among others.

"Being a mentor means helping someone see what is possible while being honest about what it will take to get there," Bickham says. "It is not about giving generic advice or telling entrepreneurs what they want to hear. Sometimes mentorship means offering encouragement, and sometimes it means asking difficult questions that help someone avoid an expensive mistake. In both situations, my responsibility is to listen, share what I have learned, and help the entrepreneur make an informed decision. ... Being a mentor also means opening doors when I can—making introductions, inviting entrepreneurs into rooms they may not have entered on their own, and helping them build relationships that can change the direction of their businesses. It also means holding them accountable for what they said they wanted to accomplish. I do not measure successful mentorship by how often someone returns to me for an answer. I measure it by whether they become more confident, more strategic, and better equipped to make decisions on their own."

Activate

Hard tech incubator Activate supports scientists in "the outset of their entrepreneurial journey." The Houston hub was introduced in 2024, and joins others in Boston, New York, and Berkley, California—where Activate is headquartered. It named its third Houston cohort this summer.

The two-year program graduated its first class of Houston fellows in 2026 and saw its first alumni IPO from Houston-based Fervo Energy, which previously participated in a Berkley cohort. Nationally, it has supported 346 fellows and 276 companies since 2015. Those companies have raised more than $6 billion in follow-on funding, according to Activate. In Houston, it has supported Houston startups like Solidec, FlowCellutions and Orbital Arc. Activate Houston is led by managing director Jeremy Pitts, who co-founded Greentown Labs in Boston. It is based out of the Ion.

Impact Hub Houston

Impact Hub Houston supports early-stage ventures at various stages of development through innovative programs that address pressing societal issues. The nonprofit organization supports social impact startups through mentorship, connections and training opportunities.

There are more than 110 Impact Hubs globally with members spanning 72 countries. Launched in 2018, Impact Hub Houston says its membership tripled by the beginning of 2026. This year brought major milestones for the community, including the launch of its Ideas to Impact Accelerator, which supported 11 founders across the health, education, food systems, civic technology and workforce development sectors. It also received funding from more than 20 international Impact Hubs to develop SYNC, a collaboration platform that 25 Impact Hubs across five continents have committed to pilot. The organization has worked with local startups including Myoviva Health, The Change Lab and INNERVERSE Inc.

MarMo Innovation

Galveston-based business incubator MarMo Innovation is focused on removing barriers to entrepreneurship. It aims to provide affordable space, education, mentorship, market access, connections and real-world opportunities that help entrepreneurs move from idea to launch to sustainable growth. The "industry-agnostic" incubator was founded in 2022 and is led by Executive Director Erica Delgadillo.

This year, the organization moved from primarily serving as a coworking and community space into a more comprehensive entrepreneurial incubator by expanding its MarMo Market, MarMo Market Jr. and Lunch LineUp programs. A major focus for MarMo is food entrepreneurship. It is developing an Incubator Kitchen, which MarMo says will support programs like its Cottage to Commercial Bootcamp and Food Biz 101. The organization also expanded its board this year and says it is diversifying its revenue through memberships, events, markets, equipment and space rentals, sponsorships, grants and new entrepreneurial programming.
