Carbon dots are emerging as a valuable method for bioimaging, therapeutics, and sensing due to their high degree of biocompatibility and reduced toxicity compared to traditional quantum dots. When modified, carbon dots have widespread medical applications, solving high-interest issues in healthcare. Carbon dots provide superior bioimaging capabilities and high resolution results. They have been used in therapeutics to deliver drugs and as photothermal agents. Carbon dots can detect the presence of ions or the change of pH, and their therapeutic and imaging potentials are frequently combined in theranostic approaches.
