Pau Gorostiza and the IRB’s Ernest Giralt and their teams synthesized two peptides which change shape upon irradiation with light, so allowing or preventing specific protein-protein interactions. “Photo-sensitive peptides act like traffic lights – they can be made to give a green or red light for cell endocytosis,” says Pau. “They allow the use of focalized light to control and study biological processes.”
