This study presents a biomimetic strategy for efficiently synthesizing polylevodopa (poly(
L
-DOPA)) nanoparticles using benzoyl peroxide
yielding materials with tailored electronic structures and significantly enhanced UV-shielding performance for advanced protective coatings.
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.
