Web16 Sep 2024 · More efficient catalytic systems need to be developed to address the existing issues of limited substrate generality, insufficient enantio-induction in certain cases, and lack of ability to construct all-carbon quaternary and heteroatom stereocenters. Summary WebSurface-enhanced Raman scattering (SERS) is a powerful technique for detection and characterization because of its extremely high sensitivity and the rich structural information that it can offer. However, most SERS substrates are composed of Au, Ag, or Cu, and a lack of substrate generality has greatly limited the breadth of the use of SERS.
