Enzyme mimic nanomaterials as nanozymes with catalytic attributes

Nanozymes are super-efficient nanomaterials with enzyme-like characteristics, as the name suggests. In the last decade, efforts have been made to develop “artificial enzymes,” which are alternatives to natural enzymes. As nanoscience and nanotechnology advance, nanozymes, which are catalytic nanomaterials having enzyme-like properties, have fascinated researchers' attention. Nanozymes with unique physicochemical properties and nanomaterials that mimic catalytic activity have gained a special interest in the industrial sectors. However, several constraints have hampered their effective deployment in industrial processes, including denaturation, time-consuming manufacturing, overall high cost-ratio, and reutilization challenges. After a brief overview of nanozyme research, an analysis of the similarities and differences between nanozymes and natural and synthetic enzymes is presented. Because of their distinct properties, nanozymes stand out in this comparison. Nanozymes have exhibited a variety of applications leveraging the physiochemical properties of nanomaterials, ranging from in vitro detection to enzyme substitution in biological systems. In addition, nanozymes have introduced a new field called nanozymology, which blends nanotechnology with enzymology. © 2022 The Authors. Published by Elsevier B.V.
