| Outline of Final Research Achievements |
Surface functionality of gold nanoparticles (AuNPs) with small organic compounds such as thiols and surfactants or biomolecules allows to control their surface properties. Thus, the surface functionalization and purification of the functionalized AuNPs form residual modification reagents are key processes in biological and therapeutic applications. Here, we devise a novel versatile methodology for surface functionalization of AuNPs through a purification of functionalized-AuNPs by using a gel filtration chromatography (GFC). We tested purification of a surface-functionalized AuNPs by bovine serum albumin (BSA)-and three different charged thiols (11-mercapto-1-undecanoic acid, 11-amino-1-undecane thiol and 1-undecane thiol), respectively. The surface-functionalized AuNPs were successfully separated with high recovery rates of more over than 90% for BSA and 85% for thiols.
