An overview on metal-doped carbon dots uses for biomedical applications

Metal-based drugs are of capital relevance for the modern medical chemistry. Nonetheless, their use has faced several issues related to toxicity and scarce biocompatibility. Metal-doped carbon dots can represent an interesting and promising solution for simultaneously exploiting the properties of metal-based drugs together with the superior biocompatibility, solubility, and photoluminescent properties of pristine carbon dots. In this concise review, we discussed the utilization of metal-doped carbon dots in biomedical applications with a focus on chemotherapy and diagnostic uses.
