Exposing ‘evil twins’

Researchers from the Cavendish Laboratory have designed a new type of sensing mechanism, combining a unique twisting property of light with frequency doubling to identify different chiral forms of molecules with extremely high sensitivity, which could be useful in the development of new drugs. The results are published in the journal Advanced Materials.

The sensing mechanism, designed by Dr Ventsislav Valev and Professor Jeremy Baumberg from the NanoPhotonics Group, in collaboration with colleagues from the UK and abroad, uses a nanopatterned gold surface in combination with powerful lasers.
