Findings from Jiangsu University Provides New Data about Quantum Dots (Dual-emission Ratiometric Fluorescence Sensors Based On Silica, Molecularly Imprinted Polymers and Carbon Quantum Dots for High-sensitivity and High-selectivity Detection of...).

Researchers from Jiangsu University in China have developed a dual-emission ratiometric fluorescence sensor for the detection of the drug sulfadiazine (SDZ). The sensor utilizes carbon quantum dots (CQD) and sulfhydryl-modified cadmium telluride quantum dots as fluorescence signals, along with a molecularly imprinted polymer. The sensor demonstrated excellent performance with a low detection limit and a wide linear range. This research provides potential for the detection of other sulfonamide antibiotics and offers insights for other molecular imprinting technologies. [Extracted from the article]
