Abstract:
The invention relates to biocompatible, soft, magneto-active polymers (MAP), the elasto-mechanical properties of which can be adjusted by a magnetic field. The invention further relates to special magnetic field systems for locally controlling the MAP and moving, separating, controlling, and influencing biological cells on the surface of the MAP material.
Abstract:
Semi-interpenetrating polymeric networks are described. More specifically, the semi-interpenetrating polymeric networks include at least two polymers that are closely associated. The first polymer is an ionic polymer that is not crosslinked. The second polymer is a cross-linked polymer that can be either another ionic polymer or a non-ionic polymer. Methods of making the semi-interpenetrating polymeric networks, articles containing the semi-interpenetrating polymeric networks, and methods of using the semi-interpenetrating polymeric networks are also described. The semi-interpenetrating polymeric networks can function as ion exchange resins.

The compositions are useful for preparing ion exchange membranes.
Abstract:
The present invention relates to a method for isolating proteins from a solution containing the proteins. The invention also relates to a method for the chromatographic separation of proteins. The present invention also relates to crosslinked hydroxylic polymer particles functionalized with temperature-responsive copolymer, and to methods of preparing such particles.
Abstract:
Process for manufacturing a composite membrane comprising a porous support and a polymeric separation layer having acidic or basic groups comprising the steps of: (i)applying a composition to a porous support; and (ii)curing the composition to form the polymeric separation layer thereon; wherein the composition comprises the components(a) a compound having one ethylenically unsaturated group; and (b) a crosslinking agent having an acrylamide group; and wherein the curing is achieved by irradiating the composition for less than 30 seconds. The membranes are useful in reverse electrodialysis e.g. for generating blue energy and have good resistance to deterioration, even under hot and high pH conditions.
