DOI: 10.1002/smll.201700278
Abstract: Photodynamic therapy (PDT) typically involves oxygen (O2 ) consumption and therefore suffers from greatly limited anticancer therapeutic efficacy in tumor hypoxia. Here, it is reported for the first time that amine-terminated, PAMAM dendrimer-encapsulated gold nanoclusters… read more here.

DOI: 10.1007/s40843-020-1492-3
Abstract: Hypoxia is a hallmark of solid tumors, and it significantly impairs the overall anticancer efficacy, particularly photodynamic therapy (PDT). Herein, a catalase-like nanovesicle with near-infrared light-responsiveness, that is, platinum/gold nanoshell encapsulated chlorin e6 (Ce6)/resveratrol (Res)… read more here.

DOI: 10.3390/antiox8090414
Abstract: Activated neutrophils release myeloperoxidase that produces the potent oxidant hypochlorous acid (HOCl). Exposure of the oxygen transport protein horse heart myoglobin (hhMb) to HOCl inhibits Iron III (Fe(III))-heme reduction by cytochrome b5 to oxygen-binding Iron… read more here.
