Tripeptide-dopamine fluorescent hybrids: a coassembly-inspired antioxidative strategy

Abstract

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 that the coassembly method can effectively resist the oxidation of dopamine molecules, thus inhibiting their melanin pathway.
