Singlet oxygen generation in hybrid porphyrin/DOPA-melanin coatings

Melanin-like coatings derived from the spontaneous oxidation of catecholamines represent an attractive and versatile platform for surface functionalization strategies. However, the intrinsic broadband absorption of melanin-like polymers and their scavenging behavior toward reactive oxygen species often limit their use in applications requiring efficient photochemical outputs. Herein, we report a practical strategy for obtaining a photodynamically active hybrid coating through the self-polymeriza
