In the preparation and storage of gold nanoparticles (Au-NPs) in colloidal form, the stability of the colloid is of utmost importance. We report a novel strategy for the synthesis of the phosphonic acid-functionalized gold nanoparticles (Au-NPs) with the high colloid stability by using ethylenediamine-tetramethylene phosphonic acid (EDTMP) as the reducing agent and its oxidation product as the stabilizing agent. The resultant phosphonic acid-functionalized Au-NPs show a remarkable colloidal stability, which likely arises from strong electrostatic effect of negatively charged phosphonate groups and the extremely hydrophilic property of phosphonate groups. Through the present method, the scope of reducing and stabilizing agents for preparation of phosphonic acid-functionalized Au-NPs extend from the -PO(3)H(2)-terminated thiols to the aminopolyphosphonates.
在胶体形式的金纳米粒子（Au-NPs）的制备和储存中，胶体的稳定性至关重要。我们报告了一种通过使用乙二胺四亚甲基膦酸（EDTMP）作为还原剂及其氧化产物作为稳定剂，合成具有高胶体稳定性的膦酸功能化金纳米粒子（Au-NPs）的新策略。所得的膦酸功能化 Au-NPs 表现出显著的胶体稳定性，这可能源于带负电荷的膦酸根基团的强静电效应和膦酸根基团的极强亲水性。通过本方法，用于制备膦酸功能化 Au-NPs 的还原剂和稳定剂的范围从 -PO(3)H(2)- 端基硫醇扩展到氨基多膦酸盐。
