Target-inhibited MCOF-Apt-AuNPs self-assembly for multicolor colorimetric detection of Salmonella Typhimurium

Pathogens detection is a crucial measure in the prevention of foodborne diseases. This study developed a novel multicolor colorimetric assay to visually detect Salmonella Typhimurium (S. Typhimurium), by utilizing the etching process of gold nanorods (AuNRs) with TMB
