Natural enzyme cascades, including the same and different kinds of enzymes, have been widely used in biosensing. However, it is still a challenge for nanozymes, mimics natural to achieve biosensing with types enzyme-like activities based on cascade reactions, such as hydrolase oxidoreductase. Considering characteristics multienzyme-like activity some proof concept, this study demonstrates Cu/Ce-MOF-808 nanozyme self-cascade catalyst hydrolase-like catechol oxidase-like activities. Taking organophosphorus pesticides an example, we constructed catalytic reaction one-step colorimetric detection isocarbophos. Specifically, can hydrolyze isocarbophos produce colorless isopropyl salicylate, which further oxidized by complexed 4-aminoantipyrine (4-AAP) red quinoneimine under neutral conditions illumination. Thus, strategy sensitive analysis developed, linear range 0.90-400.00 μg·mL-1 limit 0.42 μg·mL-1. This research presents new approach design synthesis nanozymes has great application potential field

A low collision frequency and an insufficient number of free radicals are the main problems leading to electroluminescence (ECL) efficiency luminol its derivatives. In order solve above issues, this work used nanoconfinement combined with nanozyme catalysis significantly enhance ECL efficiency. We assembled isoluminol (ILu) into hydrogen-bonded organic framework HOF-14 prepared a novel emitter ILu/HOF-14 for first time. Surprisingly, compared ILu/H2O2 system, signal ILu/HOF-14/H2O2 was increased by 33 times. This because porous structure effectively limited movement their frequency. Therefore, reaction rate between improved achieve amplification. To further increase radicals, we introduced hybrid Zn SAC@CuO2 NPs superior peroxidase (POD)-like activity. It could catalyze coreactant H2O2 produce large amount ROS (OH• O2•-), accelerating ILu improving signal. Based on research, dual-mode biosensing imaging platform constructed detect microcystin-LR (MC-LR). nonspecific trans-cleavage activity CRISPR-Cas12a system dynamic continuity amplification capability platform, detection sensitivity broadening avenues molecular diagnostic strategies.
