Main Methods:

  • Utilized surface-enhanced Raman scattering (SERS) for molecular analysis.
  • Employed tip-enhanced Raman scattering (TERS) for high-resolution probing.
  • Investigated reactions under ambient conditions with controlled excitation wavelengths and atmospheric parameters.

Main Results:

  • Successfully monitored localized protonation of 4-MPY activated by light and silver nanoparticles.
  • Demonstrated that excitation wavelength and atmospheric conditions precisely control the protonation reaction.
  • Achieved site-specific control over the protonation process.

Conclusions:

  • Light-activated protonation of 4-MPY on silver nanoparticles can be precisely controlled.
