Mussel-inspired polydopamine (PDA) coatings have gained significant attention in various fields, including biomedicine, energy, detection, and UV protection, owing to their versatile promising properties. Among these properties, shielding stands out as a key feature of PDA coatings. Nevertheless, the current methods for tuning UV-shielding properties are quite limited, only rely on thickness adjustment, which might involve additional issues like color visible light transmittance coating layer. In this study, we propose facile modular approach enhance absorption by incorporating thiol-heterocycle (TH) derivatives. Both pre- post-modification strategies can effectively impede formation conjugated structures within PDA, leading enhanced layers. More importantly, improve while reducing absorption. Furthermore, method enabled efficient regulation altering ring type (benzene or pyridine ring) substituent (methoxyl group hydrogen atom). These with demonstrate great promise applications antibacterial activity, wound healing dye degradation.

Polydopamine (PDA) and poly(5,6-dihydroxyindole) (PDHI), both typical representatives of melanin-like polymers, are emerging as promising kinds photothermal functional materials with a similar polymeric structure. However, the chaos microstructure formed by free radical polymerization monomers still hinders efficient regulation their performances. Herein, we introduced condensation between aldehydes 5,6-dihydroxyindole (DHI) monomer during process to construct more D–A pairs, which can regulate energy structures reduce optical band gaps within macromolecules. In this way, series PDHI nanoparticles (NPs) enhanced light absorption visible properties were successfully prepared used for solar power generation water desalination 91.8% evaporation efficiency. It was believed that work could provide new opportunities structure–function tailoring bioinspired further expand applications high-efficiency utilization.

In the current years, polydopamine nanoparticles (PDA NPs) have been extensively investigated as an eumelanin mimic. However, unlike natural eumelanin, PDA NPs contain no 5,6-dihydroxyindole-2-carboxylic acid (DHICA)-derived units and may be limited in certain intrinsic properties; superior eumelanin-like nanomaterials are still actively being sought. Levodopa (l-DOPA) is a precursor expected to convert into DHICA further remain within final product through covalent or physical interactions. Herein, poly(levodopa) [P(l-DOPA) NPs] were synthesized with assistance of zinc oxide supplement synthetic eumelanin. This study found that P(l-DOPA) had ∼90% DHICA-derived subunits on their surface exhibited antioxidant activity compared due looser polymeric microstructure. Benefitting from stronger ROS scavenging ability, outperformed treating cellular oxidative stress acute inflammation. research opens up new possibilities for development application novel melanin-like materials.
