The conventional notion is that enzymes, natural and nanozymes, exhibit peak activity solely within defined psychrophilic or thermophilic conditions. This work challenges the by preparing a highly efficient oxidase-mimic of Ag-based metal–organic frameworks (MOFs) (referred to as UoZ-3; UoZ stands for University Zakho), which effectively in wide-range temperatures. breakthrough not only widens working temperature range but also overcomes instability problem hydrogen peroxide limited use peroxidase-based applications. UoZ-3 showed lower Michaelis–Menten constants compared silver nanoparticles ions. Surprisingly, cold/hot adapted nanozyme exhibited sensitivity both hydrogen-atom transfer single-electron reactions with reducing agents, encompassing all antioxidant species are relevant physiological contexts. Furthermore, visual-based platform integrated smartphone was established successfully applied total capacity detection various temperatures breast cancer patients. will open an avenue research

Nanozyme-based colorimetric sensors are promising approaches for environmental monitoring, food safety, and medical diagnostics. However, developing novel nanozymes that exhibit high catalytic activity, good dispersion in aqueous solution, sensitivity, selectivity, stability is challenging. In this study, the first time, single-atom iridium-doped carbon dot (SA Ir-CDs) synthesized via a simple situ pyrolysis process. Doping dots with iridium form of single atoms to achieve maximum atomic utilization not only enhances peroxidase (POD)-like activity 178.81 U mg-1 but also improves dispersibility solutions over 30 days. Hence, SA Ir-CD platform developed mercury ions (Hg2+) detection exhibited linear relationship from 0.01 10 µm limit 4.4 nm. Notably, changes color can be observed through naked eye smartphone, enabling convenient field onsite monitoring without need sophisticated analytical equipment. an approach fabricating metal-based POD-like developed, new effective easy-to-use sensor Hg2+ constructed.
