title: Smart hydrogels from laterally-grafted peptide assembly.
abstract: Small peptides carrying laterally-grafted azobenzene units self-assemble into photo-responsive hydrogels which are applied as a smart matrix for controlling the dye molecules release. We demonstrate that a delicate balance among peptides interactions plays a pivotal role in the photo-responsive gel-sol transition.
