Aluminum plasmonic photocatalysis [PDF]

Scientific Reports, 2015
AbstractThe effectiveness of photocatalytic processes is dictated largely by plasmonic materials with the capability to enhance light absorption as well as the energy conversion efficiency. Herein, we demonstrate how to improve the plasmonic photocatalytic properties of TiO2/Al nano-void arrays by overlapping the localized surface plasmon resonance ...

Conjugated Porphyrin Polymer With Superior Charge Transfer for Photodynamic‐Immunomodulatory Prevention of CIED Infection in Diabetes

Advanced Healthcare Materials, EarlyView.
Under NIR irradiation, PTCPP generates ROS to eliminate MRSA biofilms and promote M1 macrophage polarization for phagocytosis. After bacterial clearance, the material is phagocytosed by macrophages, shifting their polarization to M2 phenotype via metabolic reprogramming, which synergistically enhances anti‐infection therapy and wound healing.
