摘要：
In the absence of a chemical reductant and other protective reagents, noble metal gold hybrid nanoparticles are successfully prepared by Co-60 gamma-ray irradiation using fifth-generation poly(amidoamine) dendrimer with surface amine-terminated group as polymeric template. The zerovalent gold is of spherical structure and the particle size is on nanometer scale range of 3-12 nm. The size distribution of gold nanoparticles displays multidispersity. The results of FTIR show that interactions between dendrimer template and gold nanoparticle exist in intra-molecule and intermolecule of fifth-generation poly(amidoamine) dendrimer.
