Abstract
This review focuses on the impact of numerous conditions on the fluorescence function of silver nanoclusters (AgNCs) as biomarkers. Factors such as particle size, structure and different ligand types are explored. First off, differential stability, sensitivity, cellular uptake, and biodistribution as well as red or blue shifts in absorption and emission wavelengths are caused by varied particle sizes. Furthermore, in the context of detecting microRNA using AgNC-based probes, the presence of a mismatched self-dimer structure is also crucial for achieving a significant red emission. In the final section, the considerable influence of ligandsdivided into primary and secondary ligandson the photoluminescence (PL) characteristics of atomically accurate AgNCs is examined with a focus on Ag29 nanoclusters.
