Numerous research fields, including chemistry, electronics, and medical
sciences, have concentrated on the production and use of novel functional
nanomaterials. Carbon, a component of all organic life forms, is essential for the
creation of nanomaterials. The modern carbon-based family component known as
carbonaceous quantum dots (CQD) was unintentionally discovered in 2004 while
single-walled carbon nanotubes were being purified. Additionally, CQDs have
exceptional qualities like outstanding photoluminescence and minimal toxic effects.
Outstanding in vitro andin vivo biomedical implications of CQDs include drug/gene
delivery, biosensor biotherapy, and theragnostic evolution. Also, CQDs can pass
through specific body sites of endothelial inflammation (epithelium of the intestinal
tract, liver, for example), tumors or penetrate capillaries due to their small size. For the
same reason, nanoparticles are more suitable for intravenous administration than
microparticles and also prevent particle aggregation and bypass emboli or thrombi
formation. This chapter describes the most contemporary applications of CQDs in
diverse biomedical fields. We hope it will provide incalculable insights to inspire
discoveries on CQD and delineate a road map toward a broader range of bio
applications.
