Advancements in Nanomedicine: Carbon Quantum Dots for Drug Delivery

Carbon quantum dots (CQDs) are a unique family of fluorescent carbon nanoparticles and nanomaterials with remarkable properties, including feasible methods of manufacture, minimal toxicity, soluble in water, biological compatibility, and ecological friendliness. Over the past 10 years, these have garnered attention from all over the world and have been used in various sectors. The development of bio analysis and biosensors has recently advanced, and we have evaluated such developments in this paper with an emphasis on their synthesis techniques. CQDs are used in biomedicine for a variety of purposes, such as fluorescent tracers, drug carriers, and drug release regulators, thanks to their nontoxicity and biocompatibility. As an example, CQDs are used as photosensitizers in photodynamic treatment to kill cancer cells. Solvents containing CQDs can be injected into an active body to produce images in vivo for detection or diagnosis. Carbon quantum dots are generating a lot of research because of their strong and controlled fluorescence emission properties. These characteristics make applications in biology, catalysis, and sensing possible.
