Quantum Dots Based Composites for Diagnostics

In recent years, quantum dots (QDs) have emerged as a promising nanomaterial with the potential to revolutionize diagnostic applications due to their unique optical and electrical capabilities. In this setting, there has been a lot of interest in incorporating QDs into composite structures to create cutting-edge diagnostic tools and methods. This summary summarizes the present status of diagnostic composites based on Quantum Dots. It describes the fundamentals of QDs and how their fluorescence can be tuned and their properties vary depending on their size, making them promising candidates for sensitive and multiplexed detection. The synthesis, functionalization, and applications of QDs-based composites across multiple diagnostic platforms are all covered in this article. Their importance in improving the efficiency of in vitro and in vivo diagnostic techniques, such as biosensing, immunoassays, cellular imaging, and targeted drug delivery, is highlighted in particular. The difficulties and factors related to QDs-based composites' biocompatibility, toxicity, and clinical translation are also discussed in the abstract. Overall, this chapter highlights the revolutionary potential of Quantum Dots based composites in diagnostics, allowing for more precise, efficient, and individual monitoring of disease.
