Stepwise Monitoring of Ligand Exchange on Gold Nanorods: From Cetyltrimethylammonium Bromide to Thiol-Functionalized Biocompatible Phosphorylcholine Using Matrix-Free LDI-TOF Mass Spectrometry
{{output}}
Gold nanorods (AuNRs) possess anisotropic optical and electronic properties, primarily determined by their aspect ratio and surface ligands, which make them attractive for applications in sensing, catalysis, and nanomedicine. While these nanorods are typically... ...
