Abstract
The present invention relates to a continuous method for producing products with molecules or macromolecules attached thereto and apparatus for carrying out this method. The method comprises the steps of: (a) placing the object on or in the proximity of a surface; (b) controlling the electrical potential of the surface with respect to its surroundings; (c) activating the object by exposing it to an electrical discharge; (d) contacting the object with the molecule or macromolecule to be attached. Such macromolecules include bacteriophage. Thus products of methods of the invention are for prevention and amelioration of bacterial contamination of the product of methods of the invention or materials in contact with said products.

A continuous method for attaching bacteriophage to an object comprising the steps of:
- placing the object on or in the proximity of a moving surface;
- controlling the electrical potential of the surface with respect to its surroundings;
- activating the object by exposing it to an electrical discharge;
- and
- contacting the object with the bacteriophage to be attached.
An apparatus for treating an object by attaching bacteriophage thereto by a continuous process comprising:
- a moving surface for supporting the object being treated;
- an electrical discharge device capable of generating an electrical discharge positioned to activate the object being treated comprising a first electrode for generating an electrical discharge and a second electrode for controlling the electrical potential of the moving surface with respect to its surroundings;
- and
- means for contacting the object being treated with the bacteriophage.
An electrode assembly for exposing an object supported on a moving surface to an electrical discharge comprising:
- an electrical discharge device capable of generating an electrical discharge, further comprising an electrode having an electrical discharge generating surface capable of generating an electrical discharge originating from an active portion of the surface, wherein the surface is movable in order to allow generation of an electrical discharge from a different portion of the surface;
- a barrier located in closely spaced separation to an inactive area of the electrode wherein the barrier separates the active portion of the electrode from an inactive portion of the electrode;
- and
- means for cooling the inactive portion of the electrode.
