Preparation of carbon quantum dots by glutathione formamide and its characterization
ABSTRACT
Carbon quantum dots are spherical carbon particles with a size less than 10 nanometers. As a new type of fluorescent material, carbon quantum dots have attracted widespread attention due to their low biological toxicity, low cost, high stability, and good water solubility. It is used in the fields of biosensors, drug carriers, cell imaging, fluorescent probes, and photocatalysis. Carbon quantum dots are mainly composed of two types of amorphous carbon nuclei and graphene oxides. The main methods for synthesizing carbon quantum dots are: top-down method and bottom-up method. Top-down methods include arc discharge, hydrothermal cutting, electrochemical oxidation, laser etching, and chemical oxidation. The bottom-up rules include pyrolysis, combustion, microwave and solution chemistry. This article reviews the properties, preparation methods and applications of carbon quantum dots, and prospects their development trends.
