![]() Within days Willson and his team of students and postdocs was creating a test with glowing nanoparticles made of phosphors, which would make the particles even more detectable and the tests more accurate. One night while he was putting her to sleep, he peered at the glow-in-the-dark star and his mind began to wander, applying its principles to science. The first idea for glow-in-the-dark technology sprang from a star pasted on the ceiling of Willson's young daughter's bedroom. “We are making those lines glow-in-the-dark so that they are more detectable, so the sensitivity of the test is be tter,” said Richard Willson, Huffington-Woestemeyer Professor of chemical and biomolecular engineering and professor of biochemical and biophysical sciences, who previously created a COVID smartphone-based app and test kit based on the technology underlying home pregnancy tests. When you read test results, you see colored lines. If you’ve taken an at-home COVID-19 or pregnancy test, then you’ve taken what is scientifically called a lateral flow assay (LFA) test, a diagnostic tool widely used because of its rapid results, low cost and ease of operation. Researchers at the University of Houston are using glow-in-the-dark materials to enhance and improve rapid COVID-19 home tests. ![]() ![]() Richard Willson, Huffington-Woestemeyer Professor of chemical and biomolecular engineering and professor of biochemical and biophysical sciences.
