Lower, S. K., Beveridge, T. J., and Hochella, M. F., Jr. "Bacterial recognition of mineral surfaces: Nanoscale interactions between Shewanella and α-FeOOH." Science 292: 1360-1363. (2001)


Description:

The desire to understand the way in which microbes (or biomolecules) interact with other surfaces is a fundamental matter that permeates environmental and medical sciences.  Composite SEM images showing biological force microscopy. A cantilever is used to translate a living microorganism (green) towards and away from another surface (blue background) with nanometer precision. Attractive or repulsive forces of interaction can be measured by monitoring the deflection of the cantilever with a laser (red). In so doing, nanoscale forces can be measured in real time between a living cell and another material in solution.
