SERS biochemical testing has made phased progress to provide new ideas for liquid biopsy analysis and other technologies
SERS biochemical testing has made phased progress to provide new ideas for liquid biopsy analysis and other technologiesSERS refers to surface-enhanced Raman, which overcomes the shortcomings of low sensitivity of Raman spectroscopy, and can obtain structural information that is not easily obtained by conventional Raman spectroscopy.
SERS can effectively analyze the adsorption orientation of compounds on the interface, the change of adsorption state, and the interface information, so it is widely used in surface research, adsorption interface surface state research, interface orientation and configuration of biological large and small molecules, conformation research, and structure analysis.

Researcher Chen Dapeng’s research team from the Integrated Circuit Leading Technology Research and Development Center of the Institute of Microelectronics and Professor Xiong Jijun from North University of China proposed an open SERS droplet sensor , which breaks the complex manufacturing process problems required by traditional substrate-based SERS devices.
The porosity and fragility of the gray nanochain structure form a SERS active droplet with abundant three-dimensional "hot spots" on the substrate in a rolling manner, thereby greatly enhancing the Raman detection performance of the droplet.
The design and development of the SERS droplet sensor provides a new detection concept for liquid biopsy analysis and other technologies.

Qingdao Energy Institute developed the second-generation Raman activated cell ejection coupled sequencing technology
Qingdao Energy Institute developed the second-generation Raman activated cell ejection coupled sequencing technology Raman activated cell ejection coupled sequencing (RACE-Seq) is one of the methods of single cell analysis of the microbiome, but its genome coverage is usually no more than 10%, and the success rate of nucleic acid amplification is low, which limits its application.
