Plasmonic metal nanostructures have been used as effective materials for enhancing the laser desorption ionization (LDI) efficiency in mass spectrometry analysis. But the ionization mechanism and the origin of initial charges have not been fully understood yet. Here we provided experimental evidence showing that the hot electron transfer in localized surface plasmon resonance (LSPR) plays a key role in ionizing molecules during the LDI process.

热电子转移促进等离子体金属纳米结构辅助的激光解吸电离质谱中的离子产生†

等离子体金属纳米结构已被用作在质谱分析中提高激光解吸电离（LDI）效率的有效材料。但是，尚未完全了解电离机理和初始电荷的起源。在这里，我们提供的实验证据表明，在局部表面等离振子共振（LSPR）中的热电子转移在LDI过程中的电离分子中起着关键作用。
