Charged polymers are macromolecules with ionizable groups. These polymeric systems
demonstrate unique properties that are qualitatively different from their neutral counterparts …

Compaction is the process in which a large DNA molecule undergoes a transition between
an elongated conformation and a very compact form. In nature, DNA compaction occurs to …

Gemini surfactants provide a significant opportunity in the development of new non-viral
delivery systems designed for gene therapy applications. This review summarizes the wide …

The compaction of long duplex DNA by cationic nanoparticles (NP) used as a primary model
of histone core particles has been investigated. We have systematically studied the effect of …

We have developed a necklace model of polyelectrolyte chain in which the necklace
structure appears as a result of the counterion condensation on the polyelectrolyte …

Motivated by recent experimental observations of a rapid spontaneous DNA coil–globule
transition on freestanding cationic lipid bilayers, we propose simple theoretical models for …

The interactions between a star-shaped hexameric cationic quaternary ammonium
surfactant PAHB and calf thymus DNA and induced DNA condensation were investigated by …

The modern state of SFM research on polymer nano‐objects including single chains is
discussed in comparison with other similar high‐resolution microscopy techniques. The …

Compaction of DNA by cationic gemini surfactant hexamethylene-1, 6-bis-(
dodecyldimethylammoniumbromide)(C12C6C12Br2) and the subsequent decompaction of …

This paper reviews recent achievements in atomic force microscopy of single polyelectrolyte
molecules adsorbed on solid surfaces. Three parts of the review refer to the visualization of …
