Electrochemical production of protein-containing polypyrrole colloids

Conducting polymer colloids containing a protein (HSA) have been produced u sing electrochemical polymerisation under hydrodynamically controlled condi tions. The effect of buffer, supporting electrolyte, pH and steric stabilis er on the colloid formation process has been evaluated. Absence of the ster ic stabiliser results in a colloid with an increased protein content. The p rotein remains active after incorporation into the colloid. (C) 1999 Elsevi er Science BN.
