A Novel Drug Delivery System Through Quantum Dots in Pharmaceutical Applications -A Review

Abstract

Owing to their small size and quantum confinement effects, semiconductor nanoparticles called quantum dots (QDs) exhibit unique electrical and optical capabilities. QDs have been studied for drug delivery, bioimaging, and sensing for pharmaceutical applications. QDs may be used in customized medicine in the future. Targeting disease biomarkers with QDs improves diagnosis and treatment. QDs can also be employed with other nanoparticles in multifunctional drug delivery and imaging systems. Targeted drug delivery systems can be prepared by coating the QDs with biocompatible polymers. Due to their intense fluorescence, QDs can also be utilized as contrast agents in bioimaging. They are promising for various applications, including biomedicine, because of their narrow emission spectra, high brightness, and long-term photostability. Dots have enormous medicinal potential owing to their unique features. Their use in drug delivery, bioimaging, and sensing has been extensively studied, and their future application in personalized medicine is promising. Further research is needed to address concerns about their toxicity and investigate alternative ingredients for their synthesis.
