چکیده
Physics, Moscow, RussiaWe consider cholesteric liquid-crystalline DNA dispersions, and show thatpolymeric (Dau-Cu) complexes, the so-called bridges, between pairs of DNA molecules may generate a super liquid-crystalline structure (BR-phase), charachterized by a soliton lattice of the spatial distribution of theorder parameter. The BR-phase could have a layered spatial structure andan abnormal optical activity that could have a bearing upon the intenseCD-band observed in DNA-dispersions.

Nanoconstructions based on double-stranded nucleic acids.
We describe the formation and properties of nanoconstruction that consists of the double-stranded DNA molecules located at distance of 35-50 A in the spatial structure of particles of their cholesteric liquid-crystalline dispersions and cross-linked by artificial nanobridges. The resulting nanostructures possess the peculiar spatial and optical properties.
متن کاملNanotechnology and Nucleic Acids
The peculiarities of two approaches in the nanodesign based on the double-stranded nucleic acid molecules are considered. Main attention is devoted to the formation and properties of nanoconstructions based on the double-stranded DNA molecules and the complexes with chitosan, fixed in the spatial structure of particles of their cholesteric liquidcrystalline dispersions, and cross-linked by arti...
متن کاملGold Nanoparticle Clusters in Quasinematic Layers of Liquid-Crystalline Dispersion Particles of Double-Stranded Nucleic Acids
The interaction between gold nanoparticles and particles of cholesteric liquid-crystalline dispersions formed by double-stranded DNA and poly(I)×poly(C) molecules is considered. It is shown that small-sized (~ 2 nm) gold nanoparticles induce two different structural processes. First, they facilitate the reorganization of the spatial cholesteric structure of the particles into a nematic one. Thi...
متن کاملThermoplastic microfluidic device for on-chip purification of nucleic acids for disposable diagnostics.
A polymeric microfluidic device for solid-phase extraction (SPE)-based isolation of nucleic acids is demonstrated. The plastic chip can function as a disposable sample preparation system for different biological and diagnostic applications. The chip was fabricated in a cyclic polyolefin by hot-embossing with a master mold. The solid phase consisted of a porous monolithic polymer column impregna...
متن کاملDefect textures in polygonal arrangements of cylindrical inclusions in cholesteric liquid crystal matrices
A systematic, computational and scaling analysis of defect textures in polygonal arrangement of cylindrical particles embedded in a cholesteric (Ch) liquid crystal matrix is performed using the Landau–de Gennes model for chiral self-assembly, with strong anchoring at the particles’ surface. The defect textures and LC phases observed are investigated as a function of chirality, elastic anisotrop...
