Abstract

Functionalized magnetic nanoparticles (MNPs) have been characterized by laser desorption/ionization mass spectrometry (LDI-MS). Quantitative information about surface ligand composition and structure for monolayer and mixed monolayer protected Fe3O4 and FePt NPs can be obtained rapidly with very little sample consumption.

摘要

功能化磁性纳米粒子(MNPs)已通过激光解吸/电离质谱(LDI-MS)进行了表征。对于单层和混合单层保护的 Fe3O4 和 FePt NPs,可以快速获得有关表面配体组成和结构的定量信息,而样品消耗非常少。
