Abstract

The method for the stabilization of colloidal particles via the synthesis and adsorption of unnatural proteins was described. The positively charged alumina surface absorbed copolypeptides from an aqueous solution which generated a steric force and made the double layer force significant. Separation between the surface was found to be independent of salt concentration and was measured using atomic force microscopy. It was found that synthesis of fusion proteins containing useful natural proteins via recombinant DNA technology could produce a wide variety of polymer sequence.
