Synthesis Strategies and Applications of Non-toxic Quantum Dots

This review provides an in-depth analysis of the latest non-toxic quantum dot (QD) synthesis strategies and their applications in optoelectronics and biomedical engineering. In addition, this review presents the development of synthetic approaches for non-heavy metal QDs that retain the desirable photophysical properties of their traditional counterparts while reducing their potential toxicity. We highlight the pivotal role of non-toxic QDs in advancing display technologies, focusing on their contribution to improving color purity and brightness in next-generation screens. In the biomedical field, applications of non-toxic QDs in bio-imaging, bio-sensing, and targeted drug delivery have been elaborated, emphasizing their enhanced biocompatibility and utility in precise diagnostics and therapeutics. The authors present insights and challenges underlining the transformative potential of non-toxic QDs for high-resolution display devices and advanced biomedical solutions to improve their functional attributes and safety for practical use.
