This NSF Small Business Innovation Research Phase II project is to synthesize cadmium-free, water-soluble, and multicolor quantum dots (QDs) by chemical doping. The project will focus on the synthesis of high quality doped ZnSe QDs using a newly developed phosphine-free approach. From these cadmium free doped derivatives with high quality blue, green, and red emissione will be produced. Then the doped core/shell QDs will be processed to make them water-soluble and biocompatible through proprietary methods for biomedicalapplications.Successful development of the proposed techniques will result in a new generation of biolabels and make significant advances in biomedical applications of such cadmium-free doped QDs. The "green" nature of the production methods, mineral precursors, natural surfactants, non-toxic and nonvolatile solvents and cadmium free QDs, will assist to maintain a sustainable environment, in addition to delivering high performance end products to the public.

这个NSF小企业创新研究第二阶段项目是通过化学掺杂合成无镉，水溶性和可降解的量子点（QD）。该项目将专注于使用新开发的无膦方法合成高质量的掺杂ZnSe量子点。从这些无镉掺杂衍生物中将产生高质量的蓝色、绿色和红色发射。该技术的成功开发将产生新一代的生物标记物，并使这种无镉掺杂的量子点在生物医学应用方面取得重大进展.生产方法的“绿色”性质、矿物前体、天然表面活性剂、无毒和非挥发性溶剂以及无镉量子点，除了向公众提供高性能的最终产品外，还将有助于维护可持续发展的环境。
