介绍了在设计的聚合物配体存在下，通过金盐还原合成荧光水溶性金纳米粒子，粒子的大小和荧光由聚合物与金的比例控制，最具荧光的纳米材料具有3%的量子产率，1.1 nm的金核和6.9 nm的流体动力学半径。
The synthesis of fluorescent water-soluble gold nanoparticles by the reduction of a gold salt in the presence of a designed polymer ligand is described, the size and fluorescence of the particles being controlled by the polymer to gold ratio; the most fluorescent nanomaterial has a 3% quantum yield, a 1.1 nm gold core and a 6.9 nm hydrodynamic radius.
