A method is presented to indirectly measure and shorten carbon nantoubes grown from the tips of atomic force microscope (AFM) probes. The measurement component exploits the nanotubes ability to elastically buckle and requires only those signals and actuators available on a standard AFM. The shortening operation is facilitated by electric arcing using a conducting niobium substrate. The shorteni...

The unfolding and folding of single protein molecules can be studied with an atomic force microscope (AFM). Many proteins with mechanical functions contain multiple, individually folded domains with similar structures. Protein engineering techniques have enabled the construction and expression of recombinant proteins that contain multiple copies of identical domains. Thus, the AFM in combinatio...

Non-contact atomic force microscopy (NC-AFM) is a powerful tool for the atomic level observation of various kinds of surfaces including even insulators, and it has been rapidly developed [1]. While the main observable value in the scanning tunneling microscope (STM) is a tunneling current between a tip and a surface, the main observable value in NC-AFM is a frequency shift of the cantilever osc...

Since its invention in 1986, the atomic force microscope (AFM) has become one of the most widely used near-field microscopes. Surfaces of hard samples are imaged routinely with atomic resolution. Soft biological samples, however, are still challenging. In this brief review, the AFM technique is introduced to the experimental biologist. We discuss recent data on imaging molecular structures of b...

We developed an in-plane Atomic Force Microscope (AFM) probe that is specifically tailored to the needs of biological applications. It features a variable stiffness, which makes the stiffness of the probe adjustable to the surface hardness of the sample [1]. The inherent capability of the in-plane AFM probe for building a massively parallel array is also an important feature that greatly affect...

Surface deformation and fracture processes of materials under external force are important for understanding and developing materials. Here, a combined horizontal universal mechanical testing machine (HUMTM)-atomic force microscope (AFM) system is developed by modifying UMTM to combine with AFM and designing a height-adjustable stabilizing apparatus. Then the combined HUMTM-AFM system is evalua...
