The GetReal Automated Probe Calibration feature from Asylum Research enables the user with just one click to fully calibrate the atomic force microscope (AFM) probe sensitivity and spring constant, enabling more consistent, more accurate results.
It also protects the probe from damage that often occurs with conventional calibration methods.
The feature is included at no extra charge exclusively with Asylum Research MFP-3D and Cypher family AFMs.

The Atomic Force Microscope (AFM), which uses a fine-tipped probe to scan surfaces at the atomic scale, will soon be augmented with a chemical sensor. This involves the use of a hollow AFM cantilever, through which a liquid - in this case mercury - is passed under pressure. The droplet of mercury at the tip acts as a sensor. This microscopic fountain pen was developed by researchers at the University of Twente's MESA+ Institute for Nanotechnology. Details of the "fountain pen's" mechanism of action were recently published in Analytical Chemistry.

Membrane proteins are the "gatekeepers" that allow information and molecules to pass into and out of a cell. Until recently, the microscopic study of these complex proteins has been restricted due to limitations of "atomic force microscopes" that are available to researchers and the one-dimensional results these microscopes reveal. Now, researchers at the University of Missouri have developed a three-dimensional microscope that will yield unparalleled study of membrane proteins and how they interact on the cellular level. These microscopes could help pharmaceutical companies bring drugs to market faster.

In collaboration with the University of Basel, an international team of researchers has observed a strong energy loss caused by frictional effects in the vicinity of charge density waves. The researchers vibrated the nanometer-sized tip of an atomic force microscope above the surface of a layered structure of niobium and selenium atoms. This may have practical significance in the control of nanoscale friction. The results have been published in the scientific journal Nature Materials.

A new state-of-the-art atomic force microscope is expected to help University of Guelph researchers find ways to fight bacterial infections and discover unique biological materials for a variety of uses. Prof. John Dutcher, Department of Physics, will use a $ 163,143 grant from the Canada Foundation for Innovation to purchase the new microscope.

These images might resemble a planetary surface but actually show a different kind of alien environment: a microscopic view across a damaged laser lens, down to the nanometre level - a millionth of a millimetre, smaller than most individual bacteria. The European Space Agency's (ESA) optics laboratory uses a powerful technique, white-light interferometric microscopy, to zoom in on tiny areas, mapping each one in a few seconds.

The world's first low cost Atomic Force Microscope (AFM) has been developed in Beijing by a group of PhD students from University College London (UCL), Tsinghua University and Peking University - using Lego. In the first event of its kind, Lego2Nano brought together students, experienced makers and scientists to take on the challenge of building a cheap and effective AFM, a device able to probe objects only a millionth of a millimeter in size - far smaller than anything an optical microscope can observe.

A high-power atomic force microscope that could revolutionize the study of materials at high temperatures and pressures is coming into focus in a Wright State University lab. Steven Higgins and his team are building a new version of the hydrothermal atomic force microscope, an instrument that could unlock scientific mysteries and be used in the study of oil production, hydrofracturing of rock layers, storage of radioactive waste and the capture and storage of atmospheric carbon dioxide.

When Felix Fischer of the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) set out to develop nanostructures made of graphene using a new, controlled approach to chemical reactions, the first result was a surprise: spectacular images of individual carbon atoms and the bonds between them.

Researchers have married two biological imaging technologies, creating a new way to learn how good cells go bad. "Let's say you have a large population of cells," said Corey Neu, an assistant professor in Purdue University's Weldon School of Biomedical Engineering. "Just one of them might metastasize or proliferate, forming a cancerous tumor. We need to understand what it is that gives rise to that one bad cell."
