We review recent experiments on the interaction of proteins with anionic polyelectrolytes in aqueous solution. Data from the literature demonstrate that proteins can form soluble complexes with linear polyelectrolytes even on the "wrong side" of the isoelectric point, that is, for pH values above the isoelectric point of the proteins under which the polyelectrolytes and the proteins are like-ch...

The formation of complexes between nanoparticles and polyelectrolytes is a key process for the control of the reactivity of manufactured nanoparticles and rational design of core shell nanostructures. In this work, we investigate the influence of the nanoparticle dielectric constant on the adsorption of a linear charged polymer (polyelectrolyte) at the surface of a neutral nanoparticle. The pol...

In this study the formation of water-soluble and water-insoluble complexes between bovine serum albumin (BSA) and biocompatible poly(N-vinyl-2-pyrrolidone-co-acrylic acid) (P(VP-co-AA); 2:1), anionic polymer, was studied at different protein, polymer concentrations and pH values. BSAP(VP-co-AA) complexes were studied by turbidimetric, gravimetric and chromatographic methods. Stability of the pr...
