纳米基质辅助激光解吸电离质谱技术以纳米材料为基质,将样品与基质混合成共结晶薄膜,激光照射时基质吸收能量使样品解吸附并电离,离子进入质量分析器检测。
其优势显著,纳米基质特殊性质增强激光与样品作用,提高电离效率与检测灵敏度,减少基质干扰以获更准质谱信息,具有高灵敏度、高分辨率,样品用量少、分析速度快且适用范围广等特点,在多领域都有着极为重要的应用价值。其中,基质材料在此技术中至关重要。它既能吸收激光能量并传递给样品分子以促进解吸电离,又能保护样品、分散样品、降低背景干扰,部分还可富集分析物。其种类多样,碳基纳米材料如碳纳米管、石墨烯等导电性好、比表面积大;硅基纳米材料像多孔硅有较大比表面积与光吸收性;金属基纳米材料如银、金纳米颗粒等可增强激光与样品作用;金属有机框架材料有高比表面积与活性位点;复合纳米材料则兼具多种材料优点,各类型基质材料在该质谱技术中均发挥独特且关键的作用。
