Abstract Detection of colorimetric signals is commonly used in various analytical methods and for testing non‐laboratory resource‐limited settings. The performance assays largely based on nanoparticles their unique optical properties. Multifunctional combining enzyme‐like catalytic properties—known as nanozymes—hold great promise applications signal‐generating labels. However, the extensive focus properties leaves overlooked. In this article, use nanozymes reviewed relying inherent nanozymes, detection a catalytically‐formed product, changes caused by product. impact extinction coefficient reaction products, well kinetic parameters sensitivity limit assays, are quantitatively evaluated. Finally, existing limitations prospects biosensors summarized.

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
