Peptide-mineral interaction images created

U.S. scientists say they have created images with the resolution of a single molecule of the interaction between peptides and a mineral surface. The scientists from the Lawrence Livermore National Lab, the Molecular Foundry at the Lawrence Berkeley National Laboratory, the University of California-Davis and the University of Alabama said they were able to create images of individual atomic layers of a mineral interacting with peptides -- protein fragments -- by improving the performance of an atomic force microscope.
