Abstract

Nanotechnology is indisputably a scientific technique that offers the prospect of new therapies, and hope, for the treatment of malignant illnesses. It is a novel technology that offers new approaches for the diagnosis and management of diverse diseases. Although the discovery of Quantum dots (QD) nano-transporters has already led to a few positive developments, QD nano-transporters are still at their initial stage, though have yet proven valuable to society. The excertion of QD indicates conversion in natural imaging along with photograph have established incredible suitability in bio-imaging, new drug development, targeted gene deliverance, biosensing, photodynamic treatment as well as diagnosis. The present review aimed to confer the significance of QD in diagnosis as well as in management of cancer. This review aims to impart fundamental insight as well as conception of QD its merits, properties, utilization as well as mode of action. This review highlight of different designing schemes of QD like hydrothermal, drop-casting, ultrasonic, solvothermal, spin-coating, atomic layer desorption, layer by layer, polymethylmethacrylate aided-transfer, electrochemical, ion beam sputtering deposition. Moreover, we have elaborated on the diverse researches related to cytotoxic examination to reveal that QDs are harmless. Concisely, the present review summarizes the fabrication schemes, current research and utilization of QD in cancer treatment.

Highlights

  • The nanoparticle is a fast-growing sector of nanotechnology that offers new possibilities for disease detection and therapy

  • Waterexquisite complexes cannot be incorporated because these exploit an aqueous approach, normal solvents can be employed with water, which is a cautious course for preparing the constantly scattered Quantum dots (QD) at the outer surface of graphene through nucleation (Wang et al, 2020)

  • TAT peptides (TATNGs) that target the nucleus were incorporated to aminefunctionalized graphene quantum dots (GQDs), which were subsequently grafted with cancer-cell-targeting folic acid (FA) modified PEG through disulfide linkage (FAPEG-TNGs)
