On-site detection of tobramycin using low-cost and ultrasensitive ratiometric fluorescence sensing platforms based on S,N-co-doped dual emission carbon quantum dots.
BACKGROUND Tobramycin (TOB) is widely used in livestock and aquaculture, but its excessive use leads to residues in animal-derived foods and the environment, threatening human health. Rapid on-site detection methods are urgently needed to ensure food safety and environmental surveillance. RESULTS We synthesized sulfu...
