We report that sodium alginate and its graft-copolymers with (2-dimethylaminoethyl) methacrylate may attach to the surface of colloidal CdS-thioglycerol quantum dots (QDs) via a ligand exchange process and result in water-soluble and highly stable QD supramolecules. Optical properties of modified QDs in water showed that the emission intensity of QDs was still high after surface passivation.
我们报告称，海藻酸钠及其与（2-二甲氨基乙基）甲基丙烯酸酯的接枝共聚物可以通过配体交换过程附着在胶体 CdS-硫代甘油量子点（QD）的表面上，从而形成水溶性和高度稳定的 QD 超分子。在水中修饰后的 QD 的光学性质表明，表面钝化后 QD 的发射强度仍然很高。
