The silver bandaid works on this principle.
One layer of Silver thread and a layer of Aluminum thread with body fluid
as the electrolyte.
Silver Ions get stripped and head for the Aluminum, getting lost in the
wound and sterilizing it.
It's the same process as removing tarnish from Silver with Aluminum foil
and salt water or vinegar or baking soda water.

Dave,
Is there any way to use silver and an anodic metal so that they would
release silver into a passive system (no conventional battery) such as
for purifying drinking water etc? Similar to the effort of the potters
for peace silver impregnated water filter, but using the galvanic
potential of metals?
If so, how exactly would it have to be hooked up? Ode and Marshall (I
think it was) implied that it was possible, but from your description,
it appears to be working backwards.
