AbstractScanning tunneling microscopy (STM) and atomic force microscopy (AFM) are capable of providing atomic‐scale images, as well as insights into functional characteristics, of surfaces. Biological materials can be studied by depositing them on appropriate substrates, and samples have been imaged with varying degrees of resolution.

Accurate Positioning of AFM Probe for AFM Based Robotic Nanomanipulation System
2006 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2006For AFM based robotic nanomanipulation system without displacement sensor, one of the key technical problems is to realize high accurate positioning of the AFM probe. To solve the problem, based on the hysteresis and nonlinear characteristics analysis of AFM PZT actuator, a new actuating method called "actuating method based on reappearing the scanning

Combination STM/AFM and AFM Images of Magnetic Domains
AIP Conference Proceedings, 1991By employing a cantilevered tip in a scanning tunneling microscope, one obtains images that show an enhancement of features associated with forces whose derivatives vary along the direction of scanning. The theory of this process is described together with experimental results showing magnetic domains on a gold coated floppy disk. Also shown are atomic

Frequency Modulation AFM (FM-AFM) is commonly operated in ultra-high vacuum, though its inception in liquids for biological samples is relatively new. Here, we highlight the ability of FM-AFM to perform molecular resolution imaging of biomembrane surfaces and to detect individual layers of structured water at similar membrane interfaces.

The AFM tweezers: integration of a tweezers function with an AFM probe
The 13th International Conference on Solid-State Sensors, Actuators and Microsystems, 2005. Digest of Technical Papers. TRANSDUCERS '05., 2005A prototype of AFM (atomic force microscope) tweezers is presented. In order to combine the function of nano objects manipulation with AFM observation, we have developed a tweezers-type AFM probe device using micromachining technology. The device has two thin wedge-type arms shaped by anisotropic etching and local oxidation of silicon techniques; one ...
