Imperial's Regius Professor Chris Toumazou led a team focused on innovative research in preventative healthcare and early detection, helping clinicians to rapidly diagnose, monitor, and treat diseases with confidence at low cost by applying microchip technology to medical devices. Through his startup company DnaNudge, Professor Toumazou, of the Department of Electrical and Electronic Engineering, applied his innovations to COVID-19, creating a highly accurate, lab-free PCR test that delivers results in around an hour.

The “CovidNudge” test is now in use in numerous NHS hospitals – including across London – and in healthcare settings worldwide. The tests were also used by arts organisations including the Royal Opera House and the Royal Ballet, where DnaNudge delivered regular testing on-site to performers and staff, and the London Symphony Orchestra.
