ABSTRACT:
Method for inhibiting live cells including eukaryotic and prokaryotic cells on an item utilized outside the human or animal body. The method includes the step of providing on the item a biologically inhibiting material including an anode material and a cathode material. Both the anode material and the cathode material have a positive galvanic potential, and the potential of the cathode material is higher than the potential of the anode material. The anode material and the cathode material each include exposed active surfaces. The exposed active surfaces include at least one of a plurality of separated areas of anode material and a plurality of separated areas of cathode material. A distance between any point on the active surface and both the adjacent cathode material and the adjacent anode material does not exceed 200 μm for inhibiting live cells including eukaryotic and prokaryotic cells on the item utilized outside the human or animal body.
