Figure 1. (a) Schematic diagram of the optical trapping-enhanced SERS optofluidic detection system; (b) effect of the single-beam optical trap module switch state on AgNPs aggregation; (c1) and (c2) ...
Surface-enhanced Raman spectroscopy is a highly sensitive molecule characterization method, significantly more sensitive than ordinary Raman spectroscopy due to the excitation of Raman modes matching ...
This fundamental limitation severely constrains the detection sensitivity. Developing single-molecule Raman spectroscopy (SM-RS) to achieve Raman signal intensity comparable to fluorescence signals ...
The medical field is a new frontier for Raman spectroscopy. Raman has already been employed in dentistry and cancer investigations, and it is now expanding into Point-of-Care (POC) applications. This ...
