Abstract
A method for desorption and ionization of an analyte from a porous, light absorbing, semiconductor is disclosed that can be used to replace conventional mass-assisted laser desorption/ionization (MALDI) in the mass spectrometry of proteins and biomolecules. The process uses the semiconductor to trap an analyte on the semiconductor. The semiconductor is illuminated by a light source and absorbs the light energy. The semiconductor then uses the light energy is to desorbed and ionize the analyte. The analyte so desorbed and ionized is suitable for detection by mass analyzers.
