Abstract

In contemporary times, nanotechnology has emerged as a notably sophisticated technological discipline. It possesses an interdisciplinary and multidisciplinary nature, spanning a wide array of domains including medical science, engineering, biology, physics, materials science, and chemistry. Utilization of nanotechnology offers a significant advantage by enabling precise manipulation and control of properties to effectively address specific challenges in various applications. In the fields of science and biomedicine, there has been extensive exploration into the use of functional nanomaterials, emerging as rapidly advancing and captivating areas of research. Diverse types of nanomaterials, including silicon nanowires, quantum dots, carbon nanotubes, and gold/silver nanoparticles, which have found extensive application in the realm of biology. Nanomedicine presents a multitude of benefits in terms of tailored drug delivery and therapeutic interventions. These advantages encompass safeguarding drugs from degradation, enhancing drug stability, prolonging circulation within the body, minimizing adverse effects, and improving targeted distribution within tissues. The current review article study aims to encompass the light-related characteristics, preparation techniques, surface modifications, biological interactions, analysis, durability, and impact on cell viability of quantum dots (QDs). This study is primarily concentrates on the use of QDs in the biomedical field for the purposes of diagnosing and treating cancer.
