摘要：

Creating hybrid nanostructures consisting of disparate nanoscale blocks is of interest for exploring new types of quantum device architectures. Here, we demonstrate the novel anchoring of monolayer-protected gold nanoclusters; of 1-3 nm diameter to sidewalls of carbon nanotubes (CNTs) via hydrophobic interactions between octanethiols capping the nanoclusters; and acetone-activated CNT surfaces. Such molecularly interlinked hybrid nanoblocks are attractive for building biocompatible nanodevices.
