Matrix-free direct laser desorption ionization of analyte has been studied on different kinds of surfaces without real success because degradation of the sample is usually observed. However, good results were obtained with the method called surface-activated laser desorption ionization (SALDI) [43] which uses graphite as the surface. But the use of porous silicon as a new surface is more promising and has led to the development of a new method called desorption ionization on silicon (DIOS) [44], Unlike the other matrix-free laser desorption ionization methods, DIOS allows ion formation from analyte with little or no degradation. [Pg.38]

Desorption/ionization on silicon. Another matrix-free approach for the analysis of small molecules is to use modified porous silicon surfaces [61]. A separate name, desorption/ionization on silicon (DIOS), has been coined for this technique [62]. In this approach, the sample is dispensed directly onto a modified porous silicon surface (e.g., silylated porous silicon) and laser-desorbed from the surface. The silicon surface is prepared from flat crystalline silicon by galvanostatic etching. [Pg.43]
