SP-ICP-MS检测黄曲霉毒素B1的方法研究|摘要：本研究开发了一种基于MNAzyme和AuNP元素标记的SP-ICP-MS同位素分析方法，用于高灵敏检测黄曲霉毒素B1。方法通过aptamer特异性结合AFB1释放引物，激活MNAzyme切割连接链，改变AuNP聚集状态，通过监测Au信号强度实现定量检测。

本研究针对单颗粒电感耦合等离子体质谱（SP-ICP-MS）中传统信号处理方法的局限性，首次系统评估了峰高作为分析信号的潜力。研究人员开发了一种基于三次多项式拟合的峰高计算新方法，在50–200 μs驻留时间范围内实现了峰高与粒径平方的线性响应。结果表明 ...

The environmental impact of engineered nanoparticles (ENPs) used in consumer products is a concern that needs to be addressed. To assess the environmental impact and risks through the use of ENPs in ...

In semiconductor manufacturing, a process called chemical mechanical planarization (CMP) is used for polishing wafer surfaces. CMP uses a slurry that contains both functional chemicals and ...

Microplastics screening has become an increasingly important part of environmental analysis, necessitating reliable analytical processes. ICP-MS has traditionally been unsuitable for measuring carbon ...
