Photo-responsive Self-assembled Coordination Architectures and Their Applications

Abstract

Development of nanomaterials that mimic enzyme-like catalytic activities (nanozymes) has drawn special attention in recent time. Nanozymes possess exclusive advantages over natural enzymes like high stability, large-scale preparation etc., and hence employed in numerous fields like biosensing, immunoassays, tissue engineering and therapeutic applications. Till now, many peroxidase mimetic nanozymes have been reported, whereas design of specifically oxidase mimicking nanomaterials got paramount importance to avoid H2O2 in these oxidase reaction systems, which show great implication in biomedical applications. In addition, oxidase-like nanozymes have shown great potential to catalyze the formation of reactive oxygen species (ROS) which can be used for many applications. External regulation of nanozymes’ activity can have additional advantages and in this regard, light is the most intrigued one. However, most of the reported nanozymes are metal/metal-oxide nanoparticles or water-insoluble extended polymeric materials. Therefore, development of discrete nano-architectures for possible use as nanozymes in aqueous medium has high potential to be explored.
