Influence of Ag Nanoparticles Incorporated into Silica Film on Ion Yield in UV Laser Desorption/Ionization Mass Spectrometry
The efficiency of UV laser desorption/ionization from the surface of mesoporous silica films containing Ag nanoparticles of various sizes has been examined using methylene blue as a probe molecule. It has been shown that a rise in both AgNPs concentration and their size to 5–12 nm intensifies the na...

| description | The efficiency of UV laser desorption/ionization from the surface of mesoporous silica films containing Ag nanoparticles of various sizes has been examined using methylene blue as a probe molecule. It has been shown that a rise in both AgNPs concentration and their size to 5–12 nm intensifies the nanoparticles stimulating effect on methylene blue desorption/ionization. The increase in Ag concentration in the silica host matrix from 3 to 10% raises fivefold the methylene blue cation peak intensity. The ion yield increase observed is discussed based on the phenomenon of local heating and local surface plasmon resonance under UV laser irradiation. |
