Colorimetric assay for tetracyclines based on europium ion-induced aggregation of gold nanoparticles

Green and rapid synthesis of biomass carbon dot-based fluorescence sensing for the sensitive determination of oxytetracycline

“…Fluorescence sensing holds the merits of rapid response, cost-effectiveness, and simplicity, and consequently, it has been widely applied in OTC detection in recent years. 6 In particular, some fluorescence methods that exhibit enticing performance by incorporating fluorescent nanomaterials, such as Au nanoclusters, 7 Ag nanoparticles, 8 CdTe quantum dots, 9 and carbon dots (CDs), 10 have drawn great attention. In particular, CDs, as a carbon-based fluorescent nanomaterial, have the advantages of biocompatibility, low toxicity, and tunable photoluminescence.…”
