摘　　要：Atomically precise gold nanoclusters (Au NCs) are an emerging class of quantum-sized nanomaterials. The intrinsic discrete electronic energy levels endowed them with fascinating electronic and optical properties [1]. However,the prepared Au NCs are often protected with hydrophobic ligands and are not dispersible in aqueous solutions, which restricts their biological applications. To overcome this limitation, some phase transfer agents have been devoted to transferring hydrophobic Au NCs into the aqueous solution[2]. However, the resulting Au NCs are generally heterogeneous and aggregated, which makes their subsequent biofunctionalization difficult to control.
