Could detecting cancer one day be as easy as taking a blood test? Wei-Chuan Shih, a University of Houston researcher and Cullen College of Engineering professor of electrical and computer engineering, has reported a 98.7-percent rate of accuracy for a method pioneered by his lab to identify cancers at their earliest stages.

The technology combines Shih’s own PANORAMA (PlAsmonic NanO-apeRture lAbel-free iMAging) with fluorescent imaging to view nanometer-sized membrane sacs, called extracellular vesicles or EVs. EVs carry different types of cargo, including proteins, nucleic acids and metabolites, throughout the bloodstream.

“We observed differences in small EV numbers and cargo in samples taken from healthy people versus people with cancer and are able to differentiate these two populations based on our analysis of the small EVs,” reports Shih, in Nature Communications Medicine. “The findings came from combining two imaging methods – our previously developed method PANORAMA and imaging of fluorescence emitted by small EVs—to visualize and count small EVs, determine their size and analyze their cargo.”

Shih introduced PANORAMA in 2020. The technology uses a glass side covered with gold nano discs that allows users to monitor changes in the transmission of light as well as determine the characteristics of nanoparticles as small as 25 nanometers in diameter. For the new publication, Shih and his team just had to count the number of small EVs in order to detect cancer.

“Using a cutoff of 70 normalized small EV counts, all cancer samples from 205 patients were above this threshold except for one sample, and for healthy samples, from 106 healthy individuals, all but three were above this cutoff, giving a cancer detection sensitivity of 99.5% and specificity of 97.3%,” says Shih.

The team was able to report 100-percent accuracy with further testing that analyzed two independent sets of samples from stage I-IV or recurrent leiomyosarcoma/gastrointestinal stromal tumors and early-and-late-stage cholangiocarcinoma combined with healthy samples.

Shih and collaborator Steven H. Lin have founded Seek Diagnostics with the goal of commercializing the technology that they’ve innovated. In 2022, the duo joined the Texas Medical Center Innovation's cancer-focused accelerator.

Houston researchers develop dissolvable implant for targeted cancer drug delivery

cancer research

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."

New Houston platform Same Day Reels launches for on-demand content creation

In The Moment

If an event doesn't happen on Instagram, did it even really happen? In today's social media-driven age of branding and audience engagement, the answer increasingly is no.

Houston entrepreneur Karen De Amat is looking to fill the online content creation needs of companies with her new venture, Same Day Reels, which launched in early August. It will serve as a platform to connect companies and brands with talent that can help turn an event into a viral moment as it is happening.

"Events move quickly, and social media moves even faster,” said De Amat. “Same Day Reels was built to help brands capture the moment while it still matters. We are creating a more efficient way for businesses and creators to work together. Brands need content faster, and creators need more opportunities to turn their talent into real work. Same Day Reels brings those needs together.”

The company is focused on adding livestreams and concurrent short video content to "activations, launches, fundraisers, grand openings, conferences, hospitality experiences, and private celebrations." Such content can significantly increase the visibility of a product or brand according to digital marketing brands like Wyzowl, whose data found 63 percent of people in 2026 prefer to learn about new products via short video.

Packages offered by Same Day Reels will include filming, editing, and publishing content within hours of the targeted event.

De Amat says that her content creation platform will be a way to preserve the excitement of events and launches by enshrining them with immediate social media-driven memories.

“Event content is no longer just something you post after the fact,” De Amat said. “It is part of how people experience, remember and share the moment.”

Previously, De Amat is also the founder and CEO of Social Behavior, an influencer marketing company she launched from her home in 2014. It quickly garnered an array of clients and thrust De Amat into the spotlight, including numerous appearances on Fox 26's The Isiah Factor. Influencer Marketing Hub named her one of the top CEOs of influencer marketing companies in Houston in 2025.

Bristol Myers Squibb to build $2.3B Houston pharma manufacturing campus

coming soon

New Jersey-based pharmaceutical giant Bristol Myers Squibb Co. has officially named Houston as the home of its new state-of-the-art manufacturing site.

The 60,000-square-foot facility represents a $2.3 billion investment, according to a news release. It is expected to create 500 skilled jobs and will be located in Houston's Generation Park.

BMS first announced that it was considering Houston among 16 other cities for the facility in May. The new hub will manufacture small molecule, biologic and antibody-drug conjugates and is part of a $40 billion commitment to invest in the United States over five years. Construction is slated to begin next year, with the facility coming online in 2030.

"We're building the domestic manufacturing capabilities needed to deliver the next generation of medicines and support future scientific breakthroughs. Houston and the state of Texas offer the talent, infrastructure, and partnership needed to help bring that vision to life," Christopher Boerner, CEO and board chair of BMS, said in the release.

The new facility will feature a modular, multi-modal design, which will allow the company to reconfigure and add to its manufacturing capabilities over time. BMS says it expects the facility to "(grow) in scale and capability well beyond its opening configuration."

"Our decision to build this state-of-the-art manufacturing campus in Houston, Texas, reflects our confidence in the region’s ability to support a world-class, digitally advanced supply operation,” Karin Shanahan, EVP and chief supply chain and operations officer of BMS, added in the release. “This facility is designed to deliver the speed, quality, and reliability that patients depend on, combining flexible, modular manufacturing with advanced digital capabilities to ensure consistent supply across multiple modalities. It strengthens our ability to operate with resilience and positions us to reliably deliver medicines to patients today while adapting future demands.”

Texas Gov. Greg Abbott shared that the state has granted BMS a $4.89 million Texas Enterprise Fund (TEF) grant for the project. TEF grants, administered by the Texas Economic Development & Tourism Office, support business relocation or expansion projects that create "new, good-paying jobs in the community and attract significant new capital investment to the state." The development is also a qualified project under the Texas Jobs, Energy, Technology, and Innovation (JETI) program.

“Texas is a global hub for life sciences, where today’s innovations shape the future of healthcare,” Abbott said in a news release. “This $2.3 billion investment by Bristol Myers Squibb in the dynamic biotech ecosystem in Houston is a testament to the depth of our skilled workforce and the pipeline of talent coming through our nation-leading technical colleges and research universities. With lower operating costs and easy access to markets across the U.S. and the world, Texas drives affordability for consumers.”

"Bristol Myers Squibb’s announcement is a tremendous win for Texas and the Houston region, further reinforcing our position as a premier destination for life sciences and advanced manufacturing,” added Greater Houston Partnership President and CEO Steve Kean.

Last fall, Eli Lilly and Co. selected Generation Park, a 4,300-acre, master-planned commercial district near Lake Houston, for its $6.5 billion manufacturing plant. More than 300 locations in the U.S. competed for the factory. Read more here.
