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