Investigation on desorption/ionization mechanism of surface-assisted laser desorption/ionization with titanium oxide nanoparticles
In this study, we investigated the correlation of the amount of desorbed neutral molecules with that of desorbed and ionized molecules in titanium oxide nanoparticle assisted laser desorption/ionization mass spectrometry. Two laser- (desorption laser and ionization laser) systems were applied to observe the amount of desorbed neutral molecules. Comparing with SALDI intensity, it is strongly suggested that the intensity has a strong relationship with the amount of neutral molecules.
