Advances in Carbon Dot-based Drug Carriers for Tumor Therapeutic Applications
Carbon dots are a new type of zero-dimensional carbon-based nanomaterials with many advantages,such as small size,low toxicity and easy surface functionalization.The emergence of carbon dots provides new ideas for targeted delivery of drugs to achieve cancer therapy.This review systematically describes the progress of the applica-tion of carbon dots as carriers for drug delivery.Firstly,the classification and synthesis methods of carbon dots are described.Secondly,the research progress of different kinds of drug delivery(chemotherapeutic drugs,photosensi-tizers,photothermal agents,etc.)based on carbon dots at home and abroad in recent years is summarized.Finally,the challenges and the application prospects are discussed,which is intended to provide some ideas for the research-ers who are engaged in the research of carbon dots in the field of drug delivery.
