質量分析によるゼラチン中の金ナノ粒子から脱離する金イオンの高感度検出
Desorption/ionization of gold ions from gold nanoparticle in a gelatin section was quantitatively evaluated by using Mass Spectrometry. Counts of gold ions were linear to the nanorod concentrations, when those were smaller than 5 nM (gold nanorods) in gelatin solutions. Limit of the detection was estimated to be 10 pM (gold nanorods) that corresponded to 60,000 (particle numbers)/mm3 in a gelatin section.
