Abstract
The use of quantum technology to deliver drugs has the potential to increase the efficacy
of many rare disease treatments. Semiconductor nanoparticles are a new type of treatment for
life-threatening disorders. The term "quantum dots" refers to semiconductor nanoparticles. These
quantum dots have a one-of-a-kind shape, size, fluorescence characteristics, and shape-dependent
optoelectronic capacities. As a result, we believe that quantum dots (QDs) has the potential to be
destined as medication carriers, biosensors, etc. Due to improvements in research, medicinal, and
clinical domains, an in-depth examination of quantum dots is now possible. Quantum dots are also
classed as carbon-based quantum dots, graphene-based quantum dots, and cadmium-based quantum
dots, with variations in their main structure, leading to the discovery of more comparable and
diversified quantum dots. Semiconductor quantum dots, or QDs, have also made tremendous progress
in the field of fluorescence bioimaging research. After examining their in vitro and in vivo
applications, we may currently use QDs as agents for gene transport, medication delivery, and enhancing
the biocompatibility of other medications. This article discusses the significant breakthroughs
and challenges in the field of quantum dots as biosensors for bioimaging, surface changes,
quantum dots in the treatment of numerous diseases, and future features of quantum dots and
their improvements in biomedical applications.
