Abstract

Thiolate-mPEG ligand-protected gold nanoparticles (AuNPs) are shown to encapsulate the water-soluble vitamins C (ascorbic acid), B3 (nicotinic acid), B6 (pyridoxine), and B9 (folic acid) in a hydrophobic medium, i.e., between 1000 and 3000 vitamin molecules per 6-nm-core AuNP (overall size: 19.2 ± 2 nm) in dichloromethane solution.
