Researchers develop technique for bacteria crowd control
May 2nd, 2007
A surprising technique to concentrate, manipulate, and separate a wide class of swimming bacteria has been identified through a collaboration between researchers at Argonne National Laboratory, Illinois Institute of technology, University of Arizona at Tucson, and Cambridge University, UK. This device could have enormous applications in biotechnology and biomedical engineering including use in miniaturized medical diagnostic kits and bioanalysis. 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...
