Optical methods for label-free detection of bacteria

HIGHLIGHTS

  • who: Pengcheng Wang et al. from the Jiangsu Province Key Laboratory of Anesthesiology, Xuzhou Medical University, Xuzhou, China have published the article: Optical Methods for Label-Free Detection of Bacteria, in the Journal: Biosensors 2022, 1171 of /2022/
  • what: This study showed that the adsorption of wild-type and mutant bacteria and the concentration of bacteria in bacterial suspension could be distinguished by physical adsorption. In this experiment, propanethiol, 3-mercaptopropionic acid, and cysteamine were modified on the surface of gold nanoparticles to improve the preferential dropped on the SERS substrate, and the SERS spectrum . . .
