Unimacromolecule exchange between bimodal micelles self-assembled by polystyrene-block-poly(acrylic acid) and Polystyrene-block-poly-(amino propylene-glycol methacrylate) in water

Article Abstract:

The unimacromolecule exchange between the bimodal micelles self-assembled by polystyrene-block-poly(acrylic acid) [PS(sub 24)-b-PAA(sub 116)] and polystyrene-block-poly(amino propylene-glycol methacrylate) [PS(sub 51)-b-PAPMA(sub 140)] in water by LLS is investigated. The unimacromolecule exchange between the bimodal micelles results in the formation of the hybrid micelles with special structure.

Protein binging to like-charge polyelectrolyte brushes by counterion evaporation

Article Abstract:

A report on a planar poly(acrylic acid) (PAA) brush as a new kind of materials coating showing a variable protein resistance that can be controlled by the ionic strength of the protein solution is presented. With the help of neutron reflectometry it was found that a silicon wafer covered with a PAA brush strongly binds bovine serum albumin (BSA) under electrostatic repulsion.
