Method for separating charged biologically active substances from liquids and the recovery thereof

Abstract

The present invention relates to a method for the at least temporary retention of charged biologically active substances such as endotoxins, viruses, and proteins from liquids, and optional later release for better determination. The object is achieved by a method for the at least temporary separation and/or detection of charged biologically active substances in a liquid by means of electrosorption and/or electrofiltration, comprising the following steps: a. providing a polymer membrane with a flat and porous metal coating at least on a first side of the polymer membrane; b. providing a counterelectrode; c. applying a voltage between the metal coating of the polymer membrane and the counterelectrode; d. bringing the polymer membrane and the counterelectrode into contact with the liquid, with the contacting being performed such that the liquid generates at least one connection between the polymer membrane and the counterelectrode.
