Target-inhibited MCOF-Apt-AuNPs self-assembly for multicolor colorimetric detection of *Salmonella Typhimurium*
H. Li, H. Xu, et al.
Discover a groundbreaking multicolor colorimetric assay for the visual detection of *Salmonella Typhimurium*, developed by researchers Hang Li, Hui Xu, Shuo Yao, Shengnan Wei, Yi Liu, Xuening Shi, Wei Zhao, and Chao Zhao. This innovative method utilizes magnetic covalent organic frameworks and aptamer-conjugated gold nanoparticles to create a nanozyme that detects *S. Typhimurium* at impressively low concentrations in various food samples.
