Force Volume

Force Volume experiment: a biotynilated SiO2 particle previously attached to a tipless cantilever has been brought in contact with a mica surface functionalizated with a streptavidin layer.
256 force-distance curves were analyzed; the resulting occurrence of detaching forces is show in dark-green. After that, both the surface and the cantilever were rinsed with a surfactant solution, then rinsed in PBS.
