Can you create a temporary bond in between an atom and a filter by electrically charging the filter? I want to be able to turn a filter on and off by electrically charging the filter so that it creates a temporary bond that blocks up the filter then, by discharging the filter, releasing the temporary bonds and allowing particles through again. Is this possible?
In a sense, you can increase and decrease flow through an osmotic filter with electricity. The process is called electro-osmosis. This can even be used to create a pressure differential in the electroosmotic pump.
