Abstract
The correlation between the time of preliminary storage of ultrasmall gold nanoparticles (GNPs) synthesized according to the Duff method and the structural aspects of their interaction with the particles of cholesteric liquid-crystalline dispersions (CLCDs) of DNA were studied. It has been established that the “age” of GNPs significantly affects the magnitude of their destructive action on the ordered organization of the DNA CLCD particles. The observed effect may be caused by both the gradual perfecting of the crystal lattice of the studied GNPs (i.e., their metallization) and the change in the chemistry of their surface over time.
研究了按照达夫方法合成的超小型金纳米粒子（GNPs）的初步储存时间与它们与 DNA 胆甾液晶分散体（CLCDs）粒子相互作用的结构方面之间的相关性。研究证实，GNPs 的 "年龄 "会显著影响其对 DNA 胆甾液晶分散体颗粒有序组织的破坏作用的大小。所观察到的影响可能是由于所研究的 GNPs 的晶格逐渐完善（即金属化）以及随着时间的推移其表面的化学性质发生了变化。
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.
