Recent Biomedical Applications of Carbon Quantum Dots in Cancer Treatment

Abstract

Carbon-based quantum dots (CQDs) have been around for a few decades. Low cell toxicity, good water solubility, excellent and tunable fluorescence properties, and the ability to dope and modify the surfaces of these CQDs make them an incredible choice for the visualization and treatment of various cancers. This Perspective analyzes some recent progress on size-color correlation, modification, and cancer treatment applications of CQDs. Synthesis and modification of CQDs to make them more efficient and biocompatible are essential to their bioapplications.
