摘要

研究了Duff法合成的超小金纳米粒子(GNPs)与不同浓度NaCl和聚乙二醇形成的DNA光活性液晶分散体(lcd)的相互作用特性。研究结果表明,GNPs对正、负向异常圆二色性(CD)信号的影响是不同的。显然,这在一定程度上是由于DNA分子的不同构象形成了相应的分散颗粒。本文还讨论了GNPs与DNA液晶显示器相互作用的动力学方面以及将超分散金“加载”到液晶显示器颗粒中的特点。

On Some Features of the Interaction of Ultrasmall Gold Nanoparticles with Liquid-Crystalline DNA Microparticles

The features of the interaction of ultrasmall gold nanoparticles (GNPs) synthesized via Duff method with particles of optically active liquid-crystalline dispersions (LCDs) of DNA formed at varying concentrations of NaCl and polyethylene glycol were studied. It was shown that the GNPs have different effects on the LCDs with positive and negative orientation of anomalous circular dichroism (CD) signal. Apparently, this is in a measure due to the various conformation of the DNA molecules that form the corresponding dispersed particles. The kinetic aspects of the interaction of GNPs with DNA LCDs and the features of “loading” ultradispersed gold into the LCD particles are also discussed.

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.
