The Center for Biofilm Engineering at Montana State University maintains a 2,000 sq. ft. Prokaryotic Imaging Facility centered around our two state-of-the-art Confocal Scanning Laser microscopes, a 2,500 sq. ft. Surface Analysis Facility centered around our TOF-SIMS equipment, and a 2,000 sq. ft. Biofilm Systems Training lab. These facilities are extensively used by our 21 Industrial Associates, workshops to train industrial colleagues are well attended, and a very large proportion of the "antibacterial" biomaterials that have been produced for use in medical devices are tested using our facilities. Several companies that are not Industrial Associates (e.g. Proctor and Gamble) make very extensive use of our facilities, on a contract research basis with higher overhead charges, and one company has used CBE technologies to construct a large (100 X 30 X 20 ft.) field test cell in which ground water flow is carefully controlled.
