Photoluminescent nanomaterials--including carbon dots, gold nanodots, gold nanoclusters, silver nanoclusters, and copper nanoclusters--have emerged as sensitive sensing materials. Carbon dots and protein-templated gold nanoclusters are biocompatible and stable against salt and photoirradiation, both having great potential for cell imaging. Some of the photoluminescent nanomaterials possess biological activities; for example, carbon dots for the inhibition of growth of cancer cells, and gold and silver nanoclusters for antibacterial activity.
