The overuse of antibiotics has led to the severe contamination of water bodies, posing a considerable hazard to human health. Therefore, the development of an accurate and rapid point-of-care testing (POCT) platform for the quantitative detection of antibiotics is necessary. In this study, Cerium oxide (CeO) and Ferrosoferric oxide (FeO) nanoparticles were simultaneously encapsulated into N-doped nanofibrous carbon microspheres to form of a novel nanozyme (CeFe-NCMzyme) with a porous structure, high surface area, and N-doped carbon material properties, leading to a considerable enhancement of the peroxidase (POD)-like activity compared with that of the CeO or FeO nanoparticles alone.

The colorimetric sensor for volatile amines (VA) detection can realize non-destructive monitoring of shrimp quality. However, its sensing performance still needs to be improved. In this study, we proposed an aerogel-type colorimetric sensor to improve VA sensing performance and realize early detection of shrimp spoilage.

Background: Ferroptosis is an iron-dependent regulatory cell death, which plays an essential role in bone loss. This study investigated whether the mechanism of risperidone (RIS)-induced bone loss is related to ferroptosis.
Methods: The schizophrenia mice were induced by administering MK-801.

Catechins in tea, as promoters of human health, have attracted widespread attention. Herein, a dual-signal mode (colorimetric and fluorescence) sensor array for catechin species fingerprinting was built based on PtNi bunched nanoparticle (PtNi-BNP)--phenylenediamine (OPD)-HO system. PtNi-BNPs catalyze the reaction between OPD and HO to produce oxidized OPD (oxOPD) with both colorimetric (yellow) and fluorescent properties.
