Mussel-Inspired Plasmonic Nanohybrids for Light Harvesting

Abstract

Core-shell plasmonic nanohybrids are synthesized through a simple solution-based process utilizing mussel-inspired polydopamine (PDA). The multi-purpose PDA not only facilitates plasmonic metal formation, but also serves as a scaffold to incorporate photosensitizers around the metal cores, as well as an adhesive between the nanohybrids and the substrate. The resulting plasmonic assembly exhibits highly enhanced light absorption in photo catalytic systems to augment artificial photosynthesis.
