World-Leading Graphene Research Facility Purchases Multiple Bruker AFMs
BILLERICA, Mass. – April 6, 2015 – Bruker Corporation (NASDAQ: BRKR) today announced an official partnership with the University of Manchester’s National Graphene Institute (NGI), joining a select list of industrial collaborators. This partnership follows NGI’s purchase of two additional atomic force microscopes (AFMs) from Bruker, a Dimension FastScan® and a Dimension Icon®. These systems join five other Bruker AFMs at the facility for research into the nanofabrication and nanoscale properties of graphene. As part of this partnership, Bruker will partially sponsor a Ph.D. student working on novel scanning probe microscopy (SPM) techniques to characterize graphene and 2D materials.
Graphene, the world’s thinnest, strongest and most conductive material, was first isolated and characterized at The University of Manchester by Sir Andre Geim and Sir Kostya Novoselov, who were awarded the Nobel Prize for Physics in 2010 for their research. This transparent, one-atom thick flat sheet of carbon has the potential to revolutionize technology, from smartphones and ultrafast broadband to drug delivery and computer chips. AFMs have demonstrated spatial resolution of less than a nanometer, and enable scientists developing materials such as graphene to understand critical mechanical, electrical, and chemical properties at the atomic scale.
“Our Bruker AFMs are anticipated to provide important new insights into nanoscale variations of graphene conductivity and work function,” said Nobel Prize winner Professor Novoselov. “Coupled with simultaneous quantitative mapping of mechanical properties, enabled by Bruker’s exclusive PeakForce Tapping®, NGI researchers hope to uncover new information that will ultimately optimize the performance of graphene-based materials and devices.”
“We are pleased that the National Graphene Institute continues to rely on our proprietary technology for its new world-class research facility, bringing their total now to seven Bruker systems,” added Paul Scagnetti, Ph.D., President of Bruker’s Nano Surfaces Division. He continued: “We are also gratified to be a part of the UK-wide Centre for Doctoral Training, where our unique AFM technologies will enable the sponsored Ph.D. student to learn even more about the physical and electrical properties of 2D materials under Professor Novoselov.”

BioScope Resolve Users Publish Results
SANTA BARBARA, California, September 30, 2014 – In a just released article in the Journal of Molecular Recognition, Dr. Hermann Schillers et al. report the first visualization of individual microvilli on living cells with atomic force microscopy. Microvilli are soft, microscopic cellular membrane protrusions present on epithelial cells that act to increase available surface area, enhance transmembrane transport, and serve as mechanosensors. Changes in their density and morphology are associated with diseases, such as celiac disease. As noted by Dr. Schillers, direct observation of microvilli on live cells had long eluded the AFM community.
“It was previously impossible to resolve the finest structures of a live cell like microvilli, but now with the BioScope Resolve, I can image them easily in one hour,” noted Dr. Schillers, lead author of the article. “This opens up exciting opportunities for new studies. Observing the structural and therefore functional integrity of microvilli on living cells will help to understand the development of microvilli-dependent diseases.”
Conventional AFMs subject live cells to high normal and lateral forces, yielding images that are dominated by the structure of the harder, underlying cytoskeleton and thus limiting their ability to track any changes in situ on the membrane of live cells. Bruker’s BioScope Resolve™ overcomes this challenge by probing the cell membrane at lower forces and with less spatial averaging from the extended probe structure and its movement through the viscous medium, bringing soft cell membrane structures into clear view for the first time.
About BioScope Resolve BioScope
Resolve is an AFM designed specifically for the highest resolution imaging of all biological samples while on the inverted optical microscope. BioScope Resolve is the only AFM to resolve individual microvilli on live cells. It provides the most complete range of capabilities for cell mechanics and molecular force spectroscopy.

PeakForce sMIM Mode Provides Enhanced Nanoscale Mapping of Permittivity and Conductivity
SANTA BARBARA, California – May 17, 2016 – Bruker’s Nano Surfaces Division today announced the release of scanning microwave impedance microscopy (sMIM) capability for its Dimension Icon® atomic force microscope (AFM) platform. The innovative sMIM technique works by reflecting a microwave signal from a nano-probe and sample interface to reveal the electrodynamic properties of the sample surface and sub-surface. The detection and processing of microwave reflectance is done in real time, allowing direct access to the permittivity and conductivity of materials. When integrated with Bruker’s unique PeakForce Tapping®, sMIM greatly expands its applications to simultaneous characterization of electrical and mechanical properties. In addition, Bruker’s new PeakForce sMIM mode enables characterization of previously challenging measurements on fragile samples, such as nanotubes, nanowires, biological samples and is ideal for electrical characterization of 2D materials.
“We greatly expanded the nano-electrical characterization capabilities for researchers in the semiconductor industries by bringing Bruker’s exclusive PeakForce Tapping to the exciting sMIM technology developed by PrimeNano Inc.” said Marco Tortonese, Ph.D., Vice President and General Manager of Bruker’s AFM Instrumentation Business. “Researchers can now benefit from the most sensitive and complete permittivity and conductivity data on even the most delicate of materials, all at the nanoscale.”
“Our sMIM technique is already changing the way nanoelectric research is being done, and we are gratified that the electronics and proprietary probes we have developed are benefitting the entire AFM community,” added Dr. Stuart Friedman, CEO of PrimeNano, Inc. “PrimeNano’s enabling sMIM technology being utilized with Bruker’s well-known Icon system, particularly in conjunction with their PeakForce Tapping mode, is another huge step in this endeavor.”
About PeakForce sMIM
The AFM-based sMIM technique accesses the reflected microwave signal from the tip-sample interface to reveal electrodynamic property data of the sample surface underneath the tip. Since it is based on the capacitive coupling between the tip and the sample, sMIM does not require making electrical contact between the sample and the substrate. This frees researchers and engineers from the tedious work of wiring and soldering that might alter the sample electrical properties and be impossible for nanoscale materials. As a near-field method, the resolution of sMIM is only limited by the tip radius of the probe, and it can easily achieve a lateral resolution of <20 nm for electrical mapping. Sub-aF sensitivity and high S/N ratios are realized by using waveguide tips with coaxial shielding. Having these unique capabilities, sMIM is superior to other AFM-based electrical modes for a broad range of applications. The versatility of PeakForce sMIM leveraging Dimension Icon and PeakForce Tapping will empower material researchers and device engineers to explore basic principles underlying functionality and perform more advanced and complete materials characterization and device failure analysis.

Dimension FastScan Bio Provides Advantages over Conventional AFMs
SANTA BARBARA, California – November 1, 2016 – Bruker’s Nano Surfaces Division reports on the groundbreaking use of a Dimension FastScan Bio™ AFM system at the University of Leeds, UK, to investigate biological and biomolecular systems at the highest resolution. Neil Thomson’s group, associated with the University’s Astbury Centre for Structural Molecular Biology, has utilized the system’s high-speed scanning, exceptional force control and high-resolution performance to characterize DNA systems, such as DNA-protein interactions and DNA origami structures, in ways that were not previously possible with other instrumentation. Furthermore, Simon Connell’s team in the School of Physics and Astronomy, where the instrument is based, has characterized the temperature-dependent dynamic behavior of critical biomimetic lipid membranes.
“The FastScan Bio AFM has improved performance over conventional AFMs, as we have achieved resolution close to the helical repeat of the DNA strands that make up the origami nanotiles,” explained Professor Neil Thomson. “The smaller FastScan probes and high stability of this AFM platform are key to obtaining high-resolution imaging under liquid. This improved resolution is helping us answer questions about the formation and stability of DNA origami for future nanomaterials applications.”
“The higher speed and stability of the FastScan Bio gives us the first direct insight into membrane nano-domain dynamics,” added Dr. Simon Connell. “The movies we capture of motion in model cell membranes under increasing temperature let us quantify domain line tensions and observe the breakdown of large lipid domains into much smaller nanoscale fluctuations. We can now directly correlate domain lifetime with size at and above the critical temperature.”
“Bruker has spent considerable effort to bring the performance and speed benefits of our FastScan platform to life science applications,” explained Marco Tortonese, Ph.D., Vice President and General Manager of Bruker’s AFM Instrumentation Business. “The FastScan Bio’s combination of resolution and productivity enables more groups like those at the University of Leeds to observe biological functions at AFM spatial resolution, ultimately increasing the pace of biological discovery.”
