ATOMIC-FORCE MICROSCOPY OF BIOMOLECULES

Biological atomic force microscopy (also known as scanning force micro scopy) has advanced in many areas. Some of the new applications of ato mic force microscopy to DNA and protein research are outlined, Advance s have occurred in both imaging and nonimaging uses of atomic farce mi croscopy. Advances in atomic force microscopy imaging have been seen b oth in the imaging of immobile samples and in the imaging of motion an d processes. Advances in nonimaging atomic force microscopy include th e use of force curves to measure intermolecular forces, force mapping, and measurements of protein motion. (C) 1996 American Vacuum Society.
