Process of Semiconductor photolithography
I. selection of photoresist. There are two basic types of photoresist: positive lithography and negative lithography, the difference is as follows II. Lithography process steps. 1. Clean silicon wafer. Remove contaminants, impurities and particles by chemical cleaning, rinsing and drying to reduce pinholes and other defects to provide photoresist adhesion. 2. Pre-drying and bottom film [...]

Progress in separation and analysis of tumor extracellular vesicles assisted by novel microfluidic
Recently, Sun Jiashu, a researcher at the National Nanoscience Center of the Chinese Academy of Sciences, and Zhang Shaohua, a professor at the Fifth Medical Center of the Chinese people's Liberation Army General Hospital, have developed a new microfluidic pulse filtration technology and a highly sensitive thermal swimming detection platform to achieve efficient separation and [...]
Rapid sorting of single cell growth phenotype of microorganisms assisted by droplet microfluidic
The screening of microbial growth phenotype is a rate-limiting step in the fields of industrial breeding, enzyme directed evolution and synthetic biology. Accurate measurement of single cell growth phenotype is the key to break through the above bottlenecks. Recently, the single-cell center of Qingdao Institute of Biological Energy and process of the Chinese Academy of Sciences has [...]
What is the speed of the micro-injection pump without continuing the pump?
As a new type of instrument with small size, simple operation and easy to use, microinjection pump (injection pump for short) has been widely used in laboratory sample injection. It can make the liquid more accurate, trace, uniform and continuous into the target instrument, and can adjust the concentration and speed of the liquid at any [...]
