Carbon Quantum Dot and Application: A Review

Non-toxic, fluorescent carbon nanoparticles or carbon quantum dots or carbon dots, a brand new category of carbon material, had high interest due to its optical and fluorescence properties with advantages of eco-friendly, low coast and simple way of synthesis. Their physical – chemical properties also depend to on functionalization and surface passivation. From the discovery of non – toxic caron nano materials, CQDs had numerous applications in different areas like sensing, biological sensing, vivo and vitro imaging, nano drug, drug carrier, drug delivery, energy, food industry, agriculture, photocatalysis and electrocatalysis etc. Here, we described here, the methods of synthesis and functionalization of carbon quantum dots, properties and applications with future prospects.
