Researchers develop technique to concentrate, manipulate and separate a wide class of swimming bacteria

The technique is based on the transmission of tiny electric current in a very thin film sample cell containing a colony of bacteria. The current produces electrolysis that changes the local pH level in the vicinity of the electrodes.
