Abstract

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.

超小型金纳米颗粒与液晶 DNA 微颗粒的相互作用：破坏与稳定

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。

期刊介绍： Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
