2023年5月31日 · Used for process control applications in semiconductor manufacturing, SEMs help ensure high-yield production of functional, high-performance chips. A SEM uses a focused electron beam to image features as small as one nanometer, making it an important instrument for characterizing semiconductor device structures.

2022年5月10日 · ChIP指染色质免疫共沉淀技术（Chromatin Immunoprecipitation,ChIP），seq 指的是 二代测序 ，那么ChIP-seq实际上也就是染色质免疫共沉淀+二代测序的一个过程。ChIP用来确定蛋白质与DNA相互作用情况，所以目前的ChIP-Seq 研究主要包括两大类应用——TF ChIP …

A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that contain information about the surface topography and composition of the sample.

扫描电子显微镜 (sem)： 对于SEM成像，去除培养基并用1mL的PBS清洗在凹微孔中形成的神经球体3次。 然后通过在室温下用1mL的2.5% 戊二醛溶液 在PBS中孵育10分钟来固定神经球体。

From simple, general tasks to advanced failure analysis (FA) techniques that need extremely precise voltage-contrast measurements on complex devices, scanning electron microscopy (SEM) imaging can provide you with a large variety of critical …
