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."

The Dimension FastScan Bio AFM from Bruker Nano Surfaces Division delivers fast scanning rates without loss of resolution or force control.
The system delivers the scanning speed required for high-resolution spatiotemporal studies. The fast scanning allows temporal investigation under physiological operating environments in fluid while exceeding the diffraction limits of optical microscopy.

With a new near-field scanning microwave microscope (NSMM) researchers from the National Institute of Standards and Technology (NIST) will improve the ability to determine the composition and physics of nanoscale materials and devices dramatically.
Few techniques can make measurements of equivalent resolution for such a wide range of samples, including semiconductors, semiconducting nanowire, materials for photovoltaic applications, magnetic materials, multiferroic materials, and even proteins and DNA.

IBM scientists have been able to differentiate the chemical bonds in individual molecules for the first time using a technique known as non-contact atomic force microscopy (AFM). The results push the exploration of using molecules and atoms at the smallest scale and could be important for studying graphene devices, which are currently being explored by both industry and academia for applications including high-bandwidth wireless communication and electronic displays.

With a five-year warranty on all its Atomic Force/Scanning Probe Microscopes, Asylum Research sets a higher standard in customer support.
The warranty covers parts and labor on Asylum's Cypher, MFP-3D Atomic Force Microscopes and MFP NanoIndenters. In the unlikely event of a breakdown during normal usage, Asylum will repair the system, or replace the broken part, at zero cost to the user.

When an oscillating AFM cantilever approaches a sample, the tip-sample interaction force influences the cantilever dynamics. The magnitude of the contact interaction force depends on the stiffness of the materials. Stiffness of the material affects sensitivity of different modes differently. This sensitivity controls the image contrast. Here, the effect of tip mass on the modal flexural sensitivity of AFM cantilever to the variations of surface stiffness and image contrast is investigated.

Bruker announced the signing of a purchase agreement to acquire Center for Tribology (CETR) for an undisclosed amount. CETR, a privately held corporation located in Silicon Valley in Campbell, CA, is projected to have calendar year 2011 revenue greater than US-$ 10 million and EBITDA greater than US-$ 2 million. The transaction is expected to close at the end of the third quarter of 2011, subject to customary closing conditions.
