Preparation of monoisotopic silver-109 nanoparticles (AgNPs) by pulsed fiber laser (PFL) ablation synthesis in solution (LASiS) with the use of a 2D galvoscanner (2D GS) is described. The procedure of covering of custom-made stainless-steel MALDI targets containing studied objects via nebulization is also presented. Examples of application of the new method (PFL-2D GS LASiS and nebulization) in mass spectrometry (MS) analyses and MS imaging (MSI) are shown. These include tests with a nonionic nucleoside and saccharide, ionic amino acids, and also a low-molecular-weight polymer. Fingerprint MS imaging is shown as an example of a fast and simple MSI procedure.
描述了使用二维振镜（2D GS）通过溶液中的脉冲光纤激光（PFL）烧蚀合成（LASiS）制备单同位素银-109纳米颗粒（AgNPs）的方法。还介绍了通过雾化覆盖包含研究对象的定制不锈钢基质辅助激光解吸电离（MALDI）靶标的过程。展示了新方法（PFL-2D GS LASiS和雾化）在质谱（MS）分析和质谱成像（MSI）中的应用实例。这些实例包括对非离子核苷和糖类、离子氨基酸以及低分子量聚合物的测试。指纹质谱成像作为一种快速简单的MSI程序示例被展示。
