Researchers at the University of Houston are using glow-in-the-dark materials to enhance the sensitivity of rapid COVID-19 home diagnostics.

The widely used lateral flow assay provides rapid results for diagnostics such as at-home COVID-19 or pregnancy tests. They also offer low costs and ease of operation. Test results on LFA diagnostics come through in 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,” said Richard Willson, who’s leading the University of Houston team. 

Willson is the Huffington-Woestemeyer professor of chemical and biomolecular engineering at the UH Drug Discovery Institute and a professor of biochemic…
