| Research Abstract |
In this project, I had carried out understanding of desorption/ionization mechanism of our new non-destructive laser desorption/ionization mass spectrometry with ultra high sensitivity by using surface plasmon excitation, and then succeeded in abstraction of main three effects related to the mechanism, which are electromagnetic enhancement effect, charge transfer effect and localized heat effect. Further, by using obtained many findings, I succeeded in improvement of our method with background free analysis.
