A Houston-based research team is tapping glow-in-the-dark materials to upgrade at-home rapid COVID-19 testing.

Researchers at the University of Houston have been rethinking the lateral flow assay (LFA) test used for at-home COVID-19 diagnostics. The traditional method indicates the sample's results with colored lines.

“We are making those lines glow-in-the-dark so that they are more detectable, so the sensitivity of the test is better,” says Richard Willson, a professor at the University of Houston, in a UH news release. He previously created a smartphone-based diagnostics app.

Willson's inspiration came from a familiar and nostalgic method — the glow-in-the-dark stars in a child's bedroom. In Willson's case, it was his daughter's bedroom, and within a few days his team of students and postdocs was designing a test featuring glowing nanoparticles made of phosphors.

The team evolved into a spin-off company called Clip Health, originally founded as Luminostics by two of the researchers. The operation is again evolving with new glowing applications.

“In this new development, there are two tricks. First, we use enzymes, proteins that catalyze reactions, to drive reactions that emit light, like a firefly. Second, we attached those light-emitting enzymes onto harmless virus particles, along with antibodies that bind to COVID proteins,” says Willson in the Royal Society of Chemistry’s journal Analyst.

The test now also can be read with a smartphone app. The group is also entertaining additional tests for other diseases.

“This technology can be used for detecting all kinds of other things, including flu and HIV, but also Ebola and biodefense agents, and maybe toxins and environmental contaminants and pesticides in food,” says Willson.

In addition to Willson, the original technology was explained in a paper with co-authors:

  • Katerina Kourentzi, University of Houston research associate professor of chemical and biomolecular engineering
  • Jacinta Conrad, Frank M. Tiller Associate Professor of Chemical and Biomolecular Engineering,
  • UH researchers Maede Chabi, Binh Vu, Kristen Brosamer, Maxwell Smith, and Dimple Chavan

4 trailblazing Houston innovators to know right now

Featured Innovators

Editor's note: Houston innovators are blazing new trails with medical breakthroughs and more. Here are four innovators to know, who have been featured on InnovationMap this month.

Dr. Ron Moses, creator of NanoEar

Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist is the creator of NanoEar, which he calls “the world’s smallest hearing aid.”

NanoEar is an implantable device that combines the invisibility of a micro-sized tympanostomy tube with more power — and a superior hearing experience — than the best behind-the-ear hearing aid.

Moses initially patented a version of the invention in 2000, but says that it took finding the right team to incorporate as NanoEar. Today, NanoEar has nine active patents. The NanoEar concept has done proof-of-concept testing on both cadavers at the University of Antwerp and on chinchillas, which are excellent models for human hearing, at Tulane University.

Thus far, NanoEar has raised about $900,000 to get its nine patents and perform its proof-of-concept experiments. The next step is to build the prototype, but completing it will take $2.75 million of seed funding. Read more.

Dr. Fong Lam, Baylor College of Medicine, and Sergey Shevkoplyas, UH

A team of Houston researchers has developed a new microfluidic device aimed at making treatments safer for children with hyperleukocytosis, a life-threatening hematologic emergency often seen in patients with leukemia.

Dr. Fong Lam, associate professor of pediatrics at Baylor College of Medicine and a pediatric intensive care physician at Texas Children’s Hospital, partnered with Sergey Shevkoplyas, a professor of biomedical engineering at UH, on the device that uses a large number of tiny channels to quickly separate blood cells by size in a process called controlled incremental filtration.

They tested whether performing cell separation with a high-throughput microfluidic device could alleviate the limitations of traditional conventional blood-filtering machines, which pose risks for pediatric patients due to their large extracorporeal volume (ECV), high flow rates and tendency to cause significant platelet loss in the patient.

“Continuously and efficiently separating leukocytes from recirculating undiluted whole blood — without device clogging and cell activation or damage — has long been a major challenge in microfluidic cell separation,” Shevkoplyas said. “Our study is the first to solve this problem.” Read more.

Elizabeth Gore, "The Big Idea with Elizabeth Gore"

Elizabeth Gore, co-founder and president of Houston's Hello Alice, debuted the first episode of her new video podcast series with Yahoo Finance on April 24.

The weekly series, known as "The Big Idea with Elizabeth Gore," will focus on providing information and resources to small business owners and sharing stories of entrepreneurship.

“Entrepreneurs and small business owners drive our country’s economy forward. With a record number of small businesses launching in our communities, my goal is to help every citizen live the American Dream. On the Big Idea, we will break down barriers for entrepreneurs and lift up opportunities for every person wanting to be their own boss,” Gore said. Read more.

Rice University student-founded companies took home a total of $100,000 in equity-free funding at the annual Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge.

Known as the NRLC, the venture competition features Rice University's top student-founded startups. The competition is open to undergraduate, graduate, and MBA students at Rice.

Five finalists were named earlier this year to pitch their five-minute pitch before the Rice entrepreneurship community on April 22. Each startup walked away with equity-free investment.

Veloci Running took home the first-place prize and $50,000. The company was founded by Tyler Strothman, a former track and field athlete and senior at Rice majoring in sport management.

Inspired by the foot pain he suffered due to the narrow toe boxes in his running shoes, Strothman decided to create a naturally shaped shoe designed to relieve lower leg tightness and absorb impact.

SteerBio took home second place and $25,000. The startup has a patented single-surgery hydrogel solution for lymphedema. It was founded by Mor Sela Golan, Martha Fowler and Alvaro Moreno Lozano. Lozano was recently named to the 2025 Rice Innovation Fellows cohort and Golan was named a Commercialization Fellow.

Third place, and $15,000, went to Labshare, which is an AI-powered web app that streamlines lab inventory and resource sharing. It was founded by Julian Figueroa Jr, John Tian, Mingyo Kang, Arnan Bawa and Daniel Kuo.
