Abstract
Tapping mode atomic force microscopy operated in the phase shift mode is used to directly visualize the surface charge on biological macromolecules under solution. A simple theory is presented which is qualitatively consistent with experimental observations, although a more complicated theoretical analysis is required for a quantitative comparison.
