Researchers at Jiangsu University in China have developed a new sensor for the ultra-sensitive detection of sulfadiazine in pork samples. The sensor, which incorporates nitrogen-doped carbon quantum dots, demonstrated a linear detection range of 0 to 30 mu mol/L and a low detection limit of 0.04 mu mol/L. Testing on actual pork samples showed high sensitivity and selectivity, with recovery rates between 95.10 and 108.30%. This advancement in sensor technology has the potential for broader applications in food safety monitoring. [Extracted from the article]

A report from Yangzhou University in Jiangsu, China discusses a novel approach to detecting DNA methylation in cancer research using molecularly imprinted polymers (MIPs). The study aims to enhance early diagnostic precision by utilizing MIPs, which offer improved specificity and sensitivity compared to current detection methods. The research suggests that the noninvasive early detection of tumor-released methylated DNA using MIPs is a promising avenue for cancer diagnostics. Financial support for this research came from the National Natural Science Foundation of China. [Extracted from the article]

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]
