UMass Amherst chemists develop molecular switch for on-demand cargo release

(University of Massachusetts at Amherst) In an unexpected finding, chemist Sankaran 'Thai' Thayumanavan and colleagues at the University of Massachusetts Amherst show for the first time how movement of a single chemical bond can compromise a membrane made up of more than 500 chemical bonds. Their system uses light as a switch to create a reversible, on-demand molecular control mechanism.
