Abstract

Formation of stable silver dispersions with a unimodal particle size distribution has been studied in aqueous solutions of oligochitosans with different molecular masses. The character of the interaction of oligochitosans with silver ions and nanoparticles has been revealed. Spectral studies have shown that hydroxyl and amino groups of oligochitosans are involved in the formation and stabilization of the aqueous dispersions containing metal nanoparticles with sizes of 45–90 nm. Such dispersions are promising for biomedical applications.

寡壳聚糖水溶液中银纳米颗粒的形成

摘要

已经研究了在具有不同分子量的低聚壳聚糖水溶液中形成具有单峰粒度分布的稳定的银分散体。寡聚壳聚糖与银离子和纳米粒子相互作用的特征已被揭示。光谱研究表明，低聚壳聚糖的羟基和氨基与包含45-90 nm大小的金属纳米颗粒的水分散体的形成和稳定有关。这种分散体有望用于生物医学应用。
