Ligand-stabilised, water-soluble gold nanoparticles of two different size ranges (2-4 and 5-8 nm) are readily prepared using monohydroxy (1-mercaptoundec-11-yl) tetraethylene glycol as a novel capping agent. These nanoparticles are as stable as alkylthiol-capped monolayer protected clusters (MPCs) and do not aggregate from aqueous solution under a wide range of stringent conditions. It is expected that this new material will be useful for a number of bio-analytical applications.
使用单羟基（1-巯基十一烷基）四甘醇作为新型封端剂，可以轻松制备出两种不同尺寸范围（2 - 4纳米和5 - 8纳米）的配体稳定的水溶性金纳米颗粒。这些纳米颗粒与烷基硫醇封端的单层保护簇（MPC）一样稳定，并且在广泛的严格条件下不会从水溶液中聚集。预计这种新材料将用于许多生物分析应用。
