Laser desorption and ionization mass spectrometry using plasmonic substrates

Abstract

This chapter describes the use of plasmonic substrates for the laser desorption/ionization in mass spectrometry. Interesting phenomenon such as polarization and wavelength dependence has been observed for the laser desorption/ionization of molecules from gold-coated porous silicon, gold nanorod arrays, and nanoparticles, and these results suggest the presence of near-field effects on the desorption/ionization process.
