Abstract
A process for making nanoparticles of biocompatible materials is described, wherein an aqueous reaction mixture comprising cerous ion, an α-amino acid, an oxidant and water is provided along with temperature conditions to effectively form nanoparticles. These biocompatible nanoparticles may be further conjugated to biologically active agents, such as plasmid DNA, siRNA or proteins, such that a cell transfection agent is formed.
