Metal-Loaded Synthetic Melanin via Oxidative Polymerization of Neurotransmitter Norepinephrine Exhibiting High Photothermal Conversion

Nano Letters, Journal Year: 2024, Volume and Issue: 24(21), P. 6353 - 6361

Published: May 17, 2024

Polydopamine (PDA)-derived melanin-like materials exhibit significant photothermal conversion owing to their broad-spectrum light absorption. However, low near-infrared (NIR) absorption and inadequate hydrophilicity compromise utilization of solar energy. Herein, we developed metal-loaded poly(norepinephrine) nanoparticles (PNE NPs) by predoping metal ions (Fe

Melanin Upcycling: Creation of Polymeric Materials from Melanin Decomposition Products

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(18), P. 7115 - 7125

Published: April 19, 2024

Melanin is a widely occurring biopolymer and has been the subject of much research, especially in dermatology. However, from resource perspective, melanin still an unutilized biomass because its complex three-dimensional cross-linked structure, which makes it challenging to handle. Here, we demonstrate upcycling by decomposing preparing polymeric materials products. A detailed study chemical decomposition products artificial melanin, i.e., polydopamine, reveals that are mainly oligomeric pyrrole derivatives containing carboxylic acids. Furthermore, experiments using natural extracted cuttlefish ink revealed composition almost identical regardless source. We proposed mechanism demonstrated preparation biobased polymer films particles The use as building blocks for material expected lead development new biodegradable polymers biomass.
