Carbon Quantum Dots, Chitosan, NanomaterialsAbstract
Carbon dots are a new class of fluorescent nanomaterials, with properties such as photoluminescence, high solubility, low toxicity, and favorable biocompatibility. They are useful for applications in biomedicine, sensors, solar cells, and photocatalysis, among others. The synthesis of quantum dots using chitosan as a starting source becomes the focus of interest for researchers due to the low cost and large-scale availability of this material. Another positive aspect of using chitosan is the possibility of reusing natural resources with the potential to reduce pollutants and their environmental impacts. As regards the synthesis methods, the hydrothermal method stands out, as it is a simple and low-cost methodology, which uses moderate temperature conditions and relatively low synthesis time. Among the main applications of chitosan-based quantum dots, applications of bioimaging and biosensors are the most reported in the literature.
