摘要

We report a bioinspired, facile strategy for synthesizing melanin-like nanoparticles via highly selective room-temperature polymerization of levodopa (L-DOPA), a native eumelanin precursor, using benzoyl peroxide. This method overcomes traditional synthesis limitations, yielding poly(L-DOPA) with covalently incorporated benzoyl fragments, and demonstrates significantly enhanced ultraviolet absorption for advanced photoprotective applications.
