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.

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.”

Houston airports poised for 1.3 million travelers on Memorial Day weekend

Taking Off

George Bush Intercontinental Airport (IAH) and William P. Hobby Airport (HOU) are estimated to see 1.3 million travelers during the Memorial Day period (May 20 - May 28). Despite large crowds, the airports say they have prepared with multiple new improvements designed to slow traffic and make check-ins easier.

“Air travel drives jobs, business and tourism — and this summer, Houston Airports is powering that growth,” said Jim Szczesniak, director of aviation for Houston Airports.

“From streamlined security to a smarter website to new flights and fresh amenities, we’re delivering improvements that support Mayor Whitmire’s call for a more user-friendly Houston. These upgrades aren’t just about moving people — they’re about moving our economy forward.”

IAH in particular has seen remarkable drops in wait times thanks to the new IAH International Arrivals Curb. Part of the $1.458 billion IAH Terminal Redevelopment Program (ITRP), it reduced airport traffic during the Christmas holidays by a whopping 99 percent, with the average wait time reaching only two minutes. Other improvements include TSA Precheck enrollment pods at both airports and the agility for international travelers to recheck bags without leaving the terminal after they have passed through customs.

The amount of travelers expected for Memorial Day is slightly below 2024 numbers, but Houston Airports expects record-breaking travel over the summer. Current estimates show 19.5 million people moving through both airports through Labor Day, a 250,000 increase over last year. Part of this can be attributed to IAH's increasing status as the gateway to Mexico, Central America, and South America, running nonstop flights to new tourist hot spots like Puerto Escondido.

In additions to streamlining the flight processes, Houston Airports are expanding concession and shop offerings. Hobby recently opened The Rustic, Chick-fil-A, Pei Wei, and Throughgood Bistro. Bush added Hip & Humble, a boutique gift and souvenir seller focused on the items for women travelers and those looking for a little luxury when they return home. And, as always, Houston Airports have some of the finest art in the country. All of it together makes traveling to and from the city much less stressful than the big crowds would portend.

"We’re ready to welcome millions with efficiency and a warm Houston spirit,” said Szczesniak. “This summer, travelers will see and feel the difference we’ve made.”

Houston e-commerce unicorn reaches $1.6B valuation with $50M fundraising round

fresh funding

Houston-based Cart.com, a provider of fulfillment and logistics services for B2C and B2B brands, has raised $50 million in venture capital, pushing its valuation to $1.6 billion. Since it was founded in 2020, Cart.com has raised $475 million.

Cart.com earned “unicorn” status in 2023 after securing a $60 million Series C round of funding. In the startup universe, “unicorn” refers to a private company that’s valued at $1 billion or more. Last year, Cart.com nailed down $130 million in debt funding, lifting its valuation to $1.2 billion.

Technically, Cart.com no longer qualifies as a startup. Rather, it’s now in “scaleup” territory. This term refers to a startup that has notched substantial growth and has maintained a stable workforce, among other positive achievements. Notable brands that have graduated from startup to scaleup include Airbnb, Peloton and Uber.

The $50 million round includes money from funds and accounts managed by BlackRock and Neuberger Berman, and new investors such as eGateway Capital, along with several unidentified venture capital firms, investors and family offices.

The company said it will use the fresh capital to fuel its global expansion through investments in infrastructure, technology, and M&A.

“Cart.com is continuing our strong growth trajectory across all operating metrics, and we intend to utilize this additional capital to accelerate the expansion of our platform and bring our customers new capabilities to enable their growth,” Omair Tariq, founder and CEO of Cart.com, said in a news release. Tariq added that his company is “well on our way to building the largest and most comprehensive platform in our space.”

Over the past 12 months, Cart.com completed its acquisition of OceanX, the fulfillment operation of direct marketing company Guthy-Renker, and Amify, an Amazon marketplace optimization and advertising platform. Bill Guthy, founder of Guthy-Renker, now sits on Cart.com’s board of directors
