Abstract: A polymer-micelle complex is disclosed. The polymer-micelle complex includes a micelle having a negative charge. The negatively charged micelle is bound electrostatically to a polymer bearing a positive charge. The complex can be in turn electrostatically bound to a siliceous material so that the complex is immobilized on the siliceous material. In addition, a composition comprising a negatively charged micelle, a positively charged polymer, and an aqueous carrier is disclosed. The aqueous carrier can exhibit salinity. In the composition, the micelle and polymer can electrostatically interact so as to form a polymer-micelle complex (which can either be soluble in the aqueous carrier or in the form of a precipitate or coacervate), or, alternatively, the polymer and micelle can remain separate such that a complex is not formed therebetween.

Abstract: Materials and methods for selectively adsorbing proteins are disclosed. Under the invention, controlled pore glass is treated with a polyelectrolyte layer which comprises at least one polymer having a cationic portion which is electrostatically attracted to the porous outer surface of the glass. The constituents of the polyelectrolyte are preferably selected to have an affinity for the predetermined protein to facilitate adsorption thereof on the polyelectrolyte treated glass. Advantageously, the materials of the present invention can be utilized to immobilize enzymes and also to separate proteins from other components in a medium.

Abstract: Described are unique preferred enzyme coacervate compositions and their use in catalyzing the reaction of substrates to which the enzyme is specific. Preferred coacervates of the invention are complex coacervates formed by complexing enzymes with polyelectrolytes.

Abstract: High molecular weight polyvinylamine hydrochloride for use as a flocculating agent in waste water systems is disclosed.
