Tripeptide-Dopamine Fluorescent Hybrids: A Coassembly-Inspired Antioxidative Strategy

Unmodified tripeptides and dopamine molecules can coassemble into fluorescent hybrid nanostructures, which break the intrinsic emission limit of both dopamines and peptides with an over-50-nm red shift. We demonstrate the coassembly method can effectively resist the oxidation of dopamine molecules, thus inhibits their melanin pathway.
