Twisted light from semiconducting nanohelices could speed drug discovery – Physics World

Researchers in the UK and the US have discovered a novel photonic effect that could make it far easier for chemists to assess the chirality of new drug candidates. Led by Ventsislav Valev at the University of Bath, the team achieved the result after synthesizing semiconductor nanohelices that emit intense, twisted blue light along a single direction when illuminated with red light. Their findings could be key to maintaining the rapid pace of modern drug discovery.
