An Experimental Study of Carbon Dust
Abstract: Carbon quantum dots (CQDs) are a replacement class of carbon-based nano material and CQD are small carbon nano particles smaller than 10 nm comprising distinctive properties due to their diverse physicochemical properties and favorable attributes like good biocompatibility, unique optical properties, low cost, ecofriendliness, high stability, CQDs have the specified advantages of low toxicity, environmental friendliness low cost and straightforward synthetic routes. Moreover, surface passivation and functionalization of CQDs leave the control of their physicochemical properties. Since their discovery, CQDs have found many applications within the fields of chemical sensing, biosensing, bioimaging, nanomedicine, photocatalysis and electrocatalysis. this text reviews the progress within the research and development of CQDs with a stress on their synthesis, the target of this work was to consolidate the present literature on the synthesis, characterization techniques, and biomedical natural resources applications of CQD. Using electrochemical oxidation, combustion/thermal, chemical change, microwave heating, arc-discharge, and laser ablation procedures from various natural resources, the paper shows recent developments in the synthesis, functionalization, and technical applications of carbon quantum dots. Natural carbon sources are used to make CQDs because they are inexpensive, environmentally friendly, and readily available.
