Synthesis of a Large Water-Soluble Gold Cluster (Au32-36) and its Properties as a Potential Label in Electron Microscopy


Large water-soluble gold clusters are used for the labelling of biological material to visualize the posi­ tion of reactive sites by electron microscopy [1]. In most investigations of this type a commercial prod­ uct was used, for which little chemical information has been published (for review see [9]). Large gold clusters can be prepared using phosphines… (More)
