Due to its polyionic character the DNA double helix is stable and biologically active only in salty aqueous media where its charge is compensated by solvent counterions. Monovalent metal ions are ubiquitous in DNA environment and they are usually considered as the possible driving force of sequence-dependent modulations of DNA structure that make it recognizable by proteins. In an effort to dir...

We report on a novel method to utilize genetically engineered M13 phages as functional nano building blocks that can form structurally aligned film and fiber matrices for tissue engineering scaffolds. Twoand three-dimensional directionally aligned long range ordered structures were constructed using shearing and polyionic complexation with cationic polymers. Further we have demonstrated that al...

Abstract In this study, the influence of direct electric current on a microcapsule was investigated. The consisted core from calcium ion and sodium alginate (SA) complex membrane formed by polyionic complexation poly(methylene-co-guanidine) (PMCG) cellulose sulfate (CS). Microcapsules showed swelling decreasing mechanical properties under applied current, anisotropic electrode side. effect is a...
