Gold Nanoclusters and Graphene Nanocomposites for Drug Delivery and Imaging of Cancer Cells

摘要

Gold nanoclusters (GNCs) have attracted wide attention owing to their outstanding surface and physical properties (for example, near-infrared photoluminescence, optical chirality, and ferromagnetism ), which has led to a wide range of applications, such as for single-molecule photonics, sensing, and biological labeling. In contrast to organic dyes and quantum dots, GNCs do not contain chemical functions and toxic heavy metals. Their near-infrared range of emission avoids interference from many biological moieties, making GNCs ideal for biological assays and cell imaging so that they may become a powerful alternative to usual fluorescence labels.
