The atomic force microscope (AFM) was used to measure the surface free energy of streptavidin crystals. To this purpose, AFM force-distance curves were acquired employing a streptavidin-functionalized tip. The jump-off-contact minimum in the force-distance curves yielded an adhesion force of 240 pN between the tip and the protein crystal. The...
