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

Red-emitting metal-organic frameworks (MOFs) are still mostly based on the use of lanthanides or functionalization with red fluorophores. However, production transition-metal-based MOFs red-emitting is scarce. This work reports synthesis a novel dual-state Zn-based MOF (denoted as UoZ-7) capability to detect target molecules in dual state, solution, and solid paper. UoZ-7 gives strong emission when excited solution state 365 nm ultraviolet (UV) lamp irradiation. Coordination-induced mechanism for enhancement restriction intramolecular rotation occurred ligand within framework structure. was successfully used tetracycline (TC) using dual-mode detection, fluorescence-based ratiometry, color tonality, TC adsorb surface, yellow-greenish emerges due aggregation-induced between UoZ-7.
