Faculty Receive Three NSF Rapid Grants For COVID-19 Testing

May 7, 2020

Three Nick Holonyak Jr., Micro and Nanotechnology Lab (HMNTL) and IGB faculty members have received NSF Rapid Response Research (RAPID) program grants, all of which aim to shorten the amount of time it takes to process a COVID-19 test. Current tests can take as long as five days for results to be returned to the patient. Although more rapid nucleic acid tests that can give a result within an hour have become available, there are reports of a high rate of false negatives among these tests.

Structurally designed 'DNA star' creates ultrasensitive test for dengue virus

December 2, 2019

By folding snippets of DNA into the shape of a five-pointed star using structural DNA nanotechnology, researchers have created a trap that captures dengue virus as it floats in the bloodstream. Once sprung, the trap – which is nontoxic and is naturally cleared from the body – lights up. It’s the most sensitive test yet for the mosquito-borne diseases.
