采用一羟基（1-巯基-11-基）四甘醇作为新型封盖剂，制备了两种不同尺寸范围（2-4 nm和5-8 nm）的配体稳定水溶性金纳米颗粒。这些纳米颗粒与烷基硫醇覆盖的单层保护簇（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。
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.
