AFM-based Virtual Nanohand Proposed for Stable Nanomanipulation

Atomic force microscopy (AFM) has become a promising tool for manipulating nano-objects to fabricate nano-structures or nano-devices. However, there are still some challenges facing the development of an AFM based robotic nanomanipulation system, such as the uncertainties associated with AFM tip and nanoparticles, the single point force and interaction between the tip and nanoparticles, and the parameter calibration of models being used. This work was published in IEEE Nanotechnology Magazine.

Atomic Force Microscopy: Short, Flexible, Reusable AFM Probe

Atomic Force Microscopy: Short, Flexible, Reusable AFM Probe

An AFM probe is a cantilever, shaped like a tiny diving board with a small, atomic-scale point on the free end. To measure forces at the molecular scale in a liquid, the probe attaches its tip to a molecule such as a protein and pulls; the resulting deflection of the cantilever is measured. The forces are in the realm of piconewtons, or trillionths of a newton. One newton is roughly the weight of a small apple. The new probe design, described in ACS Nano, is the JILA research group's third recent advance in AFM technology. more

Traumatic Brain Injury

Even the mildest form of a traumatic brain injury, better known as a concussion, can deal permanent, irreparable damage. Now, an interdisciplinary team of researchers at the University of Pennsylvania is using mathematical modeling to better understand the mechanisms at play in this kind of injury, with an eye toward protecting the brain from its long-term consequences. more
Thermal Imaging of Bacterial Cells

Thermal Imaging of Bacterial Cells

Since its invention Atomic Force Microscopy has established itself as a versatile tool for imaging material systems & associated dynamic processes. In the early 90s the technique was further developed to incorporate the use of heated probes as means of scanning the sample surface. In this study E.coli bacterial cells were used in an attempt to not only further develop and optimize the use of thermal AFM, but also to try and gain further insight into their interactions with pharmaceutical materials. more

Pulling Polymers with a Tip of an Atomic Force Microscope

In collaboration with colleagues from Berlin and Madrid, researchers at the Department of Physics at the University of Basel have pulled up isolated molecular chains from a gold surface, using the tip of an atomic force microscope (AFM). The observed signal provides insight into the detachment force and binding energy of molecules. The results have been published in the journal PNAS.

AFM-Based Force-Clamp Indentation

AFM-Based Force-Clamp Indentation

The lipid bilayer rupture was here explored by means of AFM-based force clamp. For the first time to our knowledge, this technique has been used to evaluate how lipid membranes respond when compressed under an external constant force in the range of nN. We were able to directly quantify the kinetics of the membrane rupture event and the associated energy barriers, in distinction to the classic studies performed at constant velocity.
