| Research Abstract |
Development of surface assisted LDI (SALDI) system used for analyses of low molecular compounds has been carried out. Dealloy process with electrochemical etching could successfully provide nanoporous platinum plate. The structure of nanopores strongly varied with the alloy composition. These plates were applied as SALDI-MS sample plate, desorption/ionization of organic compounds could not be detected. On the other hand, aggregated sample plate of semiconductor nanoparticles effectively
