Diagnosis Rate

Quantum dots(QDs) usually refers to nanocrystalline materials whose diameter is smaller than the exciton Bohr radius. These materials have quantum size effect,the most significant manifestation is their optical properties change with particle size.The unique optical properties make quantum dots to be Ideal markers for tumor cell tracking and targeting,such as mammary cancer, liver cancer, and melanoma.There are broad prospects in tapping the potential of this highly sensitive technology in serum and other body fluids, so as to increase the early diagnosis rate of tumors.

Graphene quantum dots (GQDs) are considerably a new member of the carbon family and shine amongst other members, thanks to their superior electrochemical, optical, and structural properties as well as biocompatibility features that enable us to engage them in various bioengineering purposes. Especially, the quantum confinement and edge effects are giving GQDs their tremendous character, while their heteroatom doping attributes enable us to specifically and meritoriously tune their prospective characteristics for innumerable operations. Considering the substantial role offered by GQDs in the area of biomedicine and nanoscience, through this review paper, we primarily focus on their applications in bio-imaging, micro-supercapacitors, as well as in therapy development. The size-dependent aspects, functionalization, and particular utilization of the GQDs are discussed in detail with respect to their distinct nano-bio-technological applications.
