Characterization of surface ligands on functionalized magnetic nanoparticles using laser desorption/ionization mass spectrometry (LDI-MS)

Nanoscale. 2013 Jun 7;5(11):5063-6. doi: 10.1039/c3nr01384g. Epub 2013 May 2.

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.
