摘要

摘要研究了用达夫法合成的超小金纳米粒子（GNPs）对 DNA 液晶分散体（LCDs）颗粒内部结构的破坏作用和稳定作用之间的相互联系，这取决于它们的有序化程度。结果表明，颗粒有序结构的 "稳定 "实际上是其 "破坏 "的结果。一种或另一种效应的主导地位取决于液晶分散体颗粒内相邻 DNA 分子之间的距离（由渗透条件决定），以及 GNPs 进入这些颗粒的效率。

Interaction of Ultrasmall Gold Nanoparticles with Liquid-Crystalline DNA Microparticles: Destruction vs Stabilization

The interconnection between the destructive and stabilizing effects of ultrasmall gold nanoparticles (GNPs) synthesized by the Duff method in relation to the internal structure of the particles of DNA liquid-crystalline dispersions (LCDs), depending on the degree of their ordering, was studied. It is shown that “stabilization” of the particles’ ordered structure is, in fact, a consequence of its “destruction.” The dominance of one or another effect depends in a complex way on the distance between neighboring DNA molecules within the particles of its LCD, determined by osmotic conditions, and the efficiency of penetration of GNPs into these particles.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
