Gold Micro-patterns for Surface-assisted Laser Desorption / Ionization Mass Spectrometry

制备了用于表面辅助激光解吸电离质谱仪(SALDI-MS)的金微纳米结构。我们成功地使用微接触印刷方法在ITO版上制备了亚微米级的金图案；然而，亚微米级图案并没有显示出有效的Saldi效率。将金纳米粒子(纳米棒)沉积在平板上以获得可达亚微米级的聚集体，然后评估这些聚集体的Saldi效率。Saldi工艺的最佳纳米结构是包含不到10个纳米棒的小聚集体。

Gold micro/nano structures were prepared to be used for surface assisted Laser desorption/ionization mass spectrometry (SALDI-MS). We succeeded in preparing sub-micron-scale patterns of gold on an ITO plate using a micro-contact printing method; however, the sub-micron-patterns did not show efficient SALDI efficiencies. Gold nanoparticles (nanorods) were deposited on a plate to obtain aggregates up-to sub-micron scales, and then the SALDI efficiencies of those were evaluated. The best nanostructures for the SALDI processes were found to be small aggregates which contained less than 10 nanorods.
