|Bacteriorhodopsin imaged with the Cypher AFM in AC mode using a short cantilever. In the original AFM image (top) missing sub-units are easily resolved (white circle) and its power spectrum shows spots outside of the 10 Angstrom circle, demonstrating sub-nanometer resolution. The lower right image is a correlation average of the original image.|
Asylum Research, the technology leader in scanning probe/atomic force microscopy (SPM/AFM), is initiating its 2012 Webinar Series on February 22. The first webinar will focus on ultra- high resolution imaging. AFM pioneer, inventor and Asylum Research co-founder, Dr. Jason Cleveland, will present "Smaller and Quieter: Ultra-high Resolution AFM Imaging."
Miniaturization of cantilevers for Atomic Force Microscopy has increased their resonant frequencies and decreased their thermal noise, allowing faster, lower noise measurements. When used in the extremely low noise CypherTM AFM, these levers have enabled significant improvements in imaging resolution in air and especially in liquids. On crystals, individual atomic point defects can now be routinely resolved, and this higher resolution also extends to biological samples. Examples to be shown include the movement of individual point defects in bacteriorhodopsin, atomic point defects in calcite, and resolution of the double-helix structure of DNA in solution.
"Recent advances in cantilever and AFM system design have enabled imaging and measurements that were previously not possible. I'll talk about these advances and show some of our latest achievements and capabilities, which I think will be of substantial interest to the full spectrum of AFM users, from beginners to the most experienced," said Dr. Cleveland.
To register, please go to www3.gotomeeting.com/register/982536366. Attendance will be limited, so early registration is recommended.
Additional Asylum Research Webinars in the coming months will include topics such as fast imaging and nanomechanical analysis tools. Details can be found at the www.AsylumResearch.com.
About Asylum Research
See what our users are saying about Asylum Research at:
Asylum Research is the technology leader in atomic force and scanning probe microscopy (AFM/SPM) for both materials and bioscience applications. Founded in 1999, we are an employee owned company dedicated to innovative instrumentation for nanoscience and nanotechnology, with over 300 years combined AFM/SPM experience among our staff. Our instruments are used for a variety of nanoscience applications in material science, physics, polymers, chemistry, biomaterials, and bioscience, including single molecule mechanical experiments on DNA, protein unfolding and polymer elasticity, as well as force measurements for biomaterials, chemical sensing, polymers, colloidal forces, adhesion, and more. Asylum’s product line offers imaging and measurement capabilities for a wide range of samples, including advanced techniques such as electrical characterization (CAFM, SKPM, EFM), high voltage piezoresponse force microscopy (PFM), thermal analysis, quantitative nanoindenting, and a wide range of environmental accessories and application-ready modules.
Asylum’s MFP-3D set the standard for AFM technology, with unprecedented precision and flexibility. The MFP-3D is the first AFM with true independent piezo positioning in all three axes, combined with low noise closed-loop feedback sensor technology. The MFP-3D offers both top and bottom sample viewing and easy integration with most commercially-available inverted optical microscopes.
Asylum’s new Cypher AFM is the world’s first new small sample AFM/SPM in over a decade, and sets the new standard as the world’s fastest and highest resolution AFM. Cypher provides low-drift closed loop atomic resolution for the most accurate images and measurements possible today, >20X faster AC imaging for images in minutes instead of minutes or hours, Spot-OnTM automated laser and photodetector alignment for easy setup, integrated thermal, acoustic and vibration control, and broad support for all major AFM/SPM scanning modes and capabilities.
Asylum Research offers the lowest cost of ownership of any AFM company. Ask us about our industry-best 2-year warranty, our legendary product and applications support, and our exclusive 6-month money-back satisfaction guarantee. We are dedicated to providing the most technically advanced AFMs for researchers who want to take their experiments to the next level. Asylum Research also distributes third party cantilevers from Olympus, Nanoworld/Nanosensors, and our own MFM and iDriveTM tips.
