polycation वाक्य

The best known polycation of mercury is, in which mercury has a formal oxidation state of + 1.
It is found as a polycation at physiological pH . Spermine is associated with nucleic acids and is thought to stabilize helical structure, particularly in viruses.
Several groups have also investigated the use of chitosan which is a naturally derived polycation as a potential replacement for PLL to fabricate alginate-chitosan ( AC ) microcapsules for cell delivery applications.
When solutions of two oppositely charged polymers ( that is, a solution of "'polycation "'and one of "'polyanion "') are mixed, a bulk complex ( precipitate ) is usually formed.
However, a better understanding of the mechanisms by which DNA can escape from endolysosomal pathway, i . e . proton sponge effect, has triggered new polymer synthesis strategies such as incorporation of protonable residues in polymer backbone and has revitalized research on polycation-based systems.
