These excellent properties have resulted in their use in a broad range of applications, including the sensing of ions (heavy metal ions, anions), biomolecules (proteins, DNA, miRNA, and enzymes), biological cells, diagnosis, and therapy. This article presents an introduction to metal quantum clusters, including a brief history of research in this system and an overview of the existing theories to understand their properties. We also discuss the synthesis methods, the various properties of quantum clusters and present a broad and updated overview of the applications of metal quantum clusters in biology.1 aKhandelwal, Puneet1 aPoddar, Pankaj  uhttps://library.ncl.res.in/content/fluorescent-metal-quantum-clusters-updated-overview-synthesis-properties-and-biological
