A team of Rice University researchers has built a technology that uses a $20 blood-glucose sensor to potentially automate dosing of practically any drug.

In a paper recently published in Nature, researchers in Caroline Ajo-Franklin’s lab shared that they were able to modify the inexpensive piece of equipment to detect afimoxifene, an estrogen inhibitor that is naturally produced by a patient’s body after taking the chemotherapy drug tamoxifen.

“The dream is to have technology similar to what’s available today for monitoring and treating variations in blood glucose, and have that be true for basically any drug,” said Ajo-Franklin, a bioscientist, cancer researcher and director of the Rice Synthetic Biology Institute in a press release from Rice University. “Millions of people use blood-glucose monitors every day. If we can use that same basic technology to monitor other drugs and biomarkers, we could move away from the one-size-fits-all dosing regimes that we’re stuck with today.”

The lead author of the study was postdoctoral research associate Rong Cai. She and the team tested more than 400 modified versions of the electron-releasing proteins (what creates the current that glucose monitors detect) until they found a version that reacted with afimoxifene. Essentially, they built an afimoxifene sensor that could reliably detect the presence of the drug.

According to Ajo-Franklin, her team is currently at work testing ways to identify drugs other than afimoxifene.

In a press release, Cai said, “The glucometer is the part that’s so well-developed. While our target is different, it’s just a matter of engineering and changing the protein on the inside. On the outside, everything will still be the same. You can still do the test with a strip or on your arm.”

Better still, she went on to say that because the signal is electrical, it can be sent to a phone or computer to be read and stored.

“That’s the part, that marriage between electricity and biology, that is very attractive,” Cai said.

4 Houston innovators to know this week

who's who

Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to four local innovators across industries — from digital health to research — recently making headlines in Houston innovation.

It's Tatiana Fofanova's goal to have Koda Health's platform — a B2B Enterprise SaaS solution that guides patients through the process of proactive healthcare planning and document authentication — active in all 50 states by the end of the first quarter of 2023. She's already halfway there.

The tech platform allows for patients and their providers to get on the same page for their care. Fofanova describes the platform as similar to TurboTax — users answer a series of questions and the program provides a care plan then shared with the patient's doctors. This greatly simplifies — and democratizes — the process for patients and providers both.

"The standard of care for advanced care planning has traditionally been left to patients to do on their own — with estate planning attorney or through a direct-to-consumer solution," Fofanova says on this week's episode of the Houston Innovators Podcast. Read more.

A team of researchers from Rice University have received a $2 million grant to develop a unique technology that speeds up the analysis of wastewater for viruses from hours to seconds. The team is based out of Rice’s George R. Brown School of Engineering and led by Rafael Verduzco, associate chair and a professor of chemical and biomolecular engineering and of materials science and nanoengineering. The four-year grant from the National Science Foundation will support the development of the technology, which includes wastewater-testing bioelectric sensors that deliver immediate notice of presence of viruses like SARS-CoV-2, which causes COVID-19, according to a news release from Rice.

“Monitoring wastewater for COVID has been pretty effective as a way to get an idea of where we are as a population,” says Verduzco in the release. “But the way it’s done is you have to sample it, you have to do a PCR test and there’s a delay. Our selling point was to get real-time, continuous monitoring to see just how much of this virus is in the wastewater.” Read more.

Houston research team snags $2M grant for virus sensing tech

money moves

A team of researchers from Rice University have received a $2 million grant to develop a unique technology that speeds up the analysis of wastewater for viruses from hours to seconds.

The team is based out of Rice’s George R. Brown School of Engineering and led by Rafael Verduzco, associate chair and a professor of chemical and biomolecular engineering and of materials science and nanoengineering. The four-year grant from the National Science Foundation will support the development of the technology, which includes wastewater-testing bioelectric sensors that deliver immediate notice of presence of viruses like SARS-CoV-2, which causes COVID-19, according to a news release from Rice.

The research project — with its partners at the Houston Health Department — have already developed water testing procedures and have analyzed samples from locations around the city. The current process includes taking samples and transferring them to Rice for analysis, but the new technology would be able to monitor systems onsite and instantly. The parties involved with this work are also collaborating with the Centers for Disease Control and Prevention Center of Excellence for wastewater epidemiology that was announced in August.

“Monitoring wastewater for COVID has been pretty effective as a way to get an idea of where we are as a population,” says Verduzco in the release. “But the way it’s done is you have to sample it, you have to do a PCR test and there’s a delay. Our selling point was to get real-time, continuous monitoring to see just how much of this virus is in the wastewater.”

The grant's co-principal investigators include Jonathan Silberg, the Stewart Memorial Professor of BioSciences and director of the Systems, Synthetic and Physical Biology Ph.D. program, and Caroline Ajo-Franklin, a professor of biosciences. Co-investigators also include Lauren Stadler, an assistant professor of civil and environmental engineering, and Kirstin Matthews, a fellow at the Baker Institute for Public Policy.

“These are engineered microbes we’re putting into wastewater, and even though they’re encapsulated, we want to know if there are concerns from health authorities and the general population,” Verduzco said. “Kirstin’s role is to look at the policy side, and also gauge public reaction and educate people about what it means when we talk about engineered bacteria.”

Intuitive Machines lands $600M satellite deal, NASA ‘spacecraft bus’ contract

space deals

Houston-based space infrastructure company Intuitive Machines has scored two astronomical deals.

The deals add to the company’s soaring success. As of June 30, Intuitive Machines had a record-high $1.8 billion backlog of orders, a $1.5 billion increase from the end of last year. The current backlog includes orders for more than 80 spacecraft.

The company, which went public in 2023, expects this year’s revenue to total $900 million to $1 billion. In the first half of 2026, Intuitive Machines generated nearly $393 million in revenue.

Intuitive Machines estimates its total available market is valued at more than $150 billion.

$600 million-plus deal represents ‘important milestone’

On Monday, Intuitive Machines said it picked up a $600 million-plus deal to develop three commercial satellites for an undisclosed customer over the course of about two years.

Intuitive Machines says it will design, manufacture, set up and support several spacecraft “for a critical communications infrastructure mission.”

Steve Altemus, the company’s CEO, says the deal represents “an important milestone for Intuitive Machines and reflects the confidence our customers place in our ability to deliver high-performance spacecraft for a broad range of mission needs.”

Company nails down NASA deal for ‘spacecraft bus’

A day after announcing the $600 million-plus deal, Intuitive Machines said it secured a new contract with NASA.

Intuitive Machines says NASA’s Jet Propulsion Laboratory in Southern California will use the company’s IM 300 “spacecraft bus” for an EAGLE-VSWIR Earth observation mission. The mission is scheduled to launch in 2028.

Aside from supplying the IM 300 bus, Intuitive Machines will carry out mission support services.

The low-Earth-orbit mission will be equipped with Intuitive Machines’ hyperspectral visible to shortwave infrared (VSWIR) instrument. This technology sees colors and details that aren’t visible to the human eye.

The instrument is “designed to perform surface biology and geology observations from Earth orbit while demonstrating technologies that could support future lunar and Mars exploration missions,” Intuitive Machines says.

Intuitive Machines builds mission-critical spacecraft, systems, and infrastructure for business and government customers. To date, the company has produced more than 300 spacecraft, delivered over 575 pounds of payload to the moon and launched about 100 satellites.

9 Houston-based companies make Fortune Global 500 list in 2026

Worldwide Rankings

Nine Houston companies landed on the 2026 Fortune Global 500 list, which ranks the world's largest corporations by revenue for the 2025 fiscal year.

Houston's showing on the list was led by energy companies, with Spring’s ExxonMobil claiming the top local spot. Here’s what Houston-area companies made the list, and where they ranked:

  • No. 15 ExxonMobil
  • No. 36 Chevron
  • No. 61 Phillip 66
  • No. 159 Sysco
  • No. 243 ConocoPhillips
  • No. 292 Enterprise Products Partners
  • No. 343 Plains GP Holdings
  • No. 460 SLB
  • No. 481 Hewlett Packard Enterprise

After 12 years as No.1, Arkansas-based Walmart was replaced this year by Seattle-based Amazon in the top spot for 2026. Amazon achieved this by bringing in $700 billion in revenue in 2025, representing a 12 percent increase from the previous year.

"Across global business, we see again and again that the leaders who are winning are those who embrace change,” Alyson Shontell, Fortune's editor in chief and chief content officer, said in a news release. "Amazon has topped the Fortune Global 500, knocking Walmart off its pedestal. The company has continually reinvented itself across new businesses and bold bets—including a $200 billion capital commitment, largely to building its capacity for AI and cloud computing, in this year alone."

The U.S. has 141 companies on the 2026 Fortune Global 500 list, which is the most of any country. Companies in America generated $15.5 trillion in aggregate revenues, a 6 percent increase from the previous year.

The number of women CEOs at Fortune Global 500 companies reached a record of 34 top leaders, who represented 6.8 percent of CEOs of companies on the list.

Technology was the standout growth industry on this year’s list, with 38 companies earning revenues that grew 20 percent to about $4 trillion in 2025, with profits climbing 36 percent to $835 billion. The financial sector accounted for the largest share of companies on the list again, with 123 companies in that sector. The energy sector claimed the No. 2 industry spot with 77 companies making the list.

In June, the Fortune 500 list was released, and Texas led the United States with 57 Fortune 500 companies headquartered in the state, generating $2.8 trillion in combined revenue.

Fast-growing Houston real estate startup surges to No. 7 on Inc. 5000

growth report

Houston-based Epique Realty has ridden the AI wave to rank among the Inc. 5000’s 10 fastest-growing private companies.

With three-year revenue growth of 23,210 percent, the AI-powered real estate brokerage appears at No. 7 on this year’s Inc. 5000 list. The 2026 list ranks private companies based on percentage revenue growth from 2022 to 2025.

Epique, founded in 2021, also ranks as the No. 1 fastest-growing company in Houston, No. 1 fastest-growing real estate company in the U.S., and No. 2 fastest-growing company in Texas.

Epique’s annual revenue surpasses $91 million

Between 2022 and 2025, the company’s annual revenue skyrocketed from $391,654 to more than $91.2 million. In 2025, the brokerage closed more than 23,000 deals and surpassed $7 billion in total sales, elevating Epique to the country’s 14th-largest real estate brokerage as measured by volume.

Epique’s network has more than 4,000 agents.

“To debut in the top 10 of the Inc. 5000 is absolute proof that when you relentlessly put agents first, exponential growth takes care of itself,” co-founder and CEO Joshua Miller said in a news release.

“We didn’t achieve this by following the industry playbook; we achieved this by burning it,” Miller added. “By fully funding our agents’ success through free health care, proprietary AI, and world-class leads, we’ve built a company where agents can finally thrive.”

The company’s other co-founders are Chris Miller, chief operating officer and vice president of expansion, and Janice Delci, chief financial officer.

Epique expands business to Canada, Mexico, Australia

The Millers and Delci have guided the company’s rapid expansion.

“Scaling our corporate support team to match [our] hyper-growth while seamlessly expanding across all 50 states and internationally to Canada, Australia, and Mexico takes an incomparable operational infrastructure,” Miller said.

“We have built an enterprise-grade technology ecosystem that allows us to absorb overhead and empower our agents at lightning speed,” he added. “This ranking validates that our disruptive model is working, and it is completely redefining the global industry standard.”

Epique launched its platform in 2023, touting itself as the industry’s first AI-powered brokerage. The startup’s platform provides AI tools for real estate agents to improve their marketing, streamline content creation, and boost engagement with clients and prospects.

Among Epique’s AI tools are:

  • ChatGPT for generation of property descriptions
  • AI-assisted creation of blog posts and agents’ bios
  • Production of Instagram quotes for social media marketing

“When we started Epique, we wanted to build a company that genuinely cared for its agents’ financial and physical well-being,” Delci says. “To see that vision translate into this level of historic record-breaking growth is a beautiful testament to the true power of radical generosity.”

Epique and fellow honorees will be recognized Oct. 14-16 at the 2026 Inc. 5000 Conference & Gala in Dallas.
