Ultrasensitive SERS detection
Ultrasensitive SERS detection is an analytical method that identifies molecules at extremely low concentrations, down to single-molecule events, by amplifying their Raman scattering on nanostructured metal surfaces.
Vibrational analysis
Vibrational analysis is a spectroscopy method that probes the vibrational modes of molecules by infrared absorption or Raman scattering, complementary techniques used to identify chemical bonds, functional groups, and molecular structure.
Vibrational microscopy
Vibrational microscopy is a family of label-free imaging techniques that maps molecular vibrations by infrared absorption or Raman scattering to reveal a sample's chemical composition.
Vibrational spectroscopy
Vibrational spectroscopy is a family of analytical techniques, mainly infrared absorption and Raman scattering, that identifies molecules from the characteristic frequencies of their vibrating bonds.
Vibrational Stark effect
The vibrational Stark effect (VSE) is the shift of a molecule's vibrational frequencies by an external electric field, underpinning spectroscopy that measures electric fields in proteins, solvents, and at electrodes.
Waveguide-enhanced Raman spectroscopy
Waveguide-enhanced Raman spectroscopy (WERS) is an analytical technique in which laser light guided along a waveguide enhances the Raman spectra of molecules on its surface, used for biochemical sensing.
