The incorporation of unnatural amino acids represents a unique mechanism for the modulation of protein function. This approach has been utilized to generate photoswitchable GFP mutants, capable of demonstrating modulated fluorescence upon exposure to UV irradiation. Overall these photosensitive GFP mutants can be employed in various biosensing and diagnostic techniques to better understand protein function and processing. (C) 2014 Elsevier Ltd.

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.
