Photoluminescent sensing systems using gold (Au) and carbon nanomaterials (NMs) are presented. Strategies for preparation of Au nanodots, Au nanoclusters, and carbon dots (C dots) are briefly described. Based on analyte induced fluorescence quenching, gold nanodots have been used for quantitation of various important analytes such as platelet-derived growth factor (PDGF) and phospholipase C. Carbon dots are stable against salt and photoirradiation, which have become suitable materials in cell imaging. Like conventional liposomes, C-dot liposomes can be used as an efficient carrier for drugs to inhibit the growth of malignant tumors. In addition, C-dot liposomes possessing photoswitching properties hold great potential for cell labeling. When compared to conventional organic dyes, they are brighter, and more stable, biocompatible, and efficient.
