Copper element is one of the oldest metals in terms of its use. Copper (Cu) element is an essential micronutrient element that is involved in the metabolism of living forms and must be taken regularly into the body due to its ability to catalyze oxidation-reduction reactions. Copper is used due to its biological importance and positive properties such as high solubility in water, high biocompatibility, low cost and easy availability. With the development of nanotechnology, Cu nanoclusters (Cu NCs) synthesized with both cheap and biocompatible methods are being studied for their use as sensors by taking advantage of their strong fluorescence properties. It has been determined that Cu NCs can be used in the determination of toxic materials such as pesticides, cancer drugs, and heavy metals with high sensitivity and high precision. The study draws attention to both the importance of environmentally friendly synthesis strategies and the potential of Cu nanoclusters in biosensor technology. This study demonstrates that Cu NCs obtained by green synthesis can be produced in accordance with the sustainability principle and can be used as a reliable fluorescent probe in chemical-biological sensing systems. Thus, both the production of environmentally friendly nanomaterials is encouraged and a contribution is made to advanced analysis technologies.
