We found that the expression of autophagic typical protein, LC3-II, in DCs cocultured with a negative charged polymer was much faster than that of positive charged polymer.
Multilayer films, containing the enzyme and nitrogen doped graphene (NG) dispersed in the biocompatible positively-charged polymer chitosan {chit+ NG + GOx }, together with the negatively charged polymer poly styrene sulfonate), PSS−, were assembled.
Terada, A. et al. Bacterial adhesion to and viability on positively charged polymer surfaces.
Using capillary electrophoresis, we showed that the stereociliary glycocalyx acts as a negatively charged polymer brush.
She dips it into a water solution of a positively charged polymer, then into one of a negatively charged polymer; the process is repeated until many layers are built up.
Power dissipation is observed when an electrical current is passed through the charged polymer matrix.
But previously, researchers using the method layered a positively charged polymer with negatively charged nanotubes, resulting in films that were only half nanotubes.
Heparin, a highly charged polymer and an allosteric activator of the serpin, is associated with major adverse effects.
The hybrid approach presented here might enable preparation of mechanically strong nanocomposite hydrogels consisting of strongly or weakly charged polymer chains of different architecture.
In this work, we fabricate four PIC hydrogels using four positively charged trimethyl-ammonium monomers with slightly different chemical moieties and a same negatively charged polymer.
In contrast, BSA and 3T3 cells significantly adsorbed on and adhered to positively or negatively charged polymer brushes fabricated by the same procedure.
