Force spectroscopy. (Instruments).The Digital Instruments PicoForce scanning probe microscope control system is available for demanding nanoscience and materials research. The PicoForce system, combined with powerful software developed specifically for force spectroscopy Force spectroscopy is a dynamic analytical technique that allows the study of the mechanical properties of polymer molecules and/or chemical bonds. Since this is a single-molecule technique, i.e. it allows a researcher much finer control over the molecule under study. , is said to enable accurate force measurements and manipulation of material samples at the pico-Newton level. The MultiMode PicoForce utilizes an atomic force microscope atomic force microscope (AFM), device that uses a spring-mounted probe to image individual atoms on the surface of a material. Unlike the scanning tunneling microscope, which is also a scanning probe microscope, the AFM can be used on materials that do not conduct , a scanner with closed-loop control of the z-axis that is said to accurately control tip-sample separation and new software developed specifically for force spectroscopy.
