Abstract

Carbonaceous quantum dots (CQDs) is defined as a subclass of carbon nanoparticles, which offer a size of around 10 nm, and have unique characteristics and a wide range of applications in diverse fields. CQDs have attained widespread attention due to their excellent abilities in several domains, including sensing, nanomedicine and environmental remediation. The mode of synthesis for CQDs is quite simple and inexpensive via methods such as microwave pyrolysis, arc-discharge, etc. CQDs are entitled to diverse physical, chemical and biological properties. Besides this, CQDs have various functional groups present on their surface that improve the properties, specifically the catalytic performance by a phenomenon called charge transfer. The physical, optical, electrical, and biological features of CQDs are explored in this chapter.
