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。

由于微塑料的普遍存在及其对生态系统和人类健康的潜在风险，它们日益受到关注。由于其微小的尺寸、化学多样性以及与天然胶体的共存，对其进行全面分析变得困难。在这里，我们评估了两种新兴的单颗粒技术：单颗粒电感耦合等离子体质谱（SP ICP-MS）和光 ...

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 ...

与ICP-OES（电感耦合等离子体发射光谱仪）相比，ICP-MS具有检出限更低、线性动态范围更宽、干扰更少等优点。 ICP-MS，电感耦合等离子体质谱仪，一种分析仪器，以ICP（电感耦合等离子体）作为质谱的高温离子源，通过离子质荷比不同对被测样品进行测定分析。

Carbon is difficult to measure with ICP-MS due to its high ionization potential and its presence in both the argon used to generate the plasma and in reagents. Because of this, high backgrounds exist ...

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