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.

Scanning Electron Microscopy: 3D SEM Metrology for 10 nm Structures

PML researchers have devised an idea for determining the three-dimensional shape of features as small as 10 nanometers wide. The model-based method compares data from scanning electron microscope (SEM) images with stored entries in a library of three dimensional (3D) shapes to find a match and to determine the shape of the sample. The work provides a powerful new way to characterize nanostructures.

Single-Particle Imaging: Bright Future for Protein Nanoprobes

The term a "brighter future" might be a cliché, but in the case of ultra-small probes for lighting up individual proteins, it is now most appropriate. Researchers at the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered surprising new rules for creating ultra-bright light-emitting crystals that are less than 10 nanometers in diameter. These ultra-tiny but ultra-bright nanoprobes should be a big asset for biological imaging, especially deep-tissue optical imaging of neurons in the brain. more

Exploring Nanoscale Viscoelastic Properties

Development of advanced materials relies on a detailed understanding of nanoscale morphology and mechanical properties. Atomic Force Microscopy (AFM) has become a key tool in material science by providing this information. Contact Resonance imaging has emerged as a powerful AFM technique for its ability to quantitatively characterize the viscoelastic response of materials, its applicability to a wide range of materials, and its ability to provide this information quickly and at high resolution.

Scanning Transmission Electron Microscopy: Improving Imaging at the Atomic Scale

When capturing images at the atomic scale, even tiny movements of the sample can result in skewed or distorted images - and those movements are virtually impossible to prevent. Now microscopy researchers at North Carolina State University have developed a new technique that accounts for that movement and eliminates the distortion from the finished product.

New Holographic Process Uses Image-Stabilized X-Ray Camera

New Holographic Process Uses Image-Stabilized X-Ray Camera

The efficiency of the new method is based on a X-ray focussing optics being firmly fixed to the object to be imaged. While this approach initially provides a blurry image, this can be focussed in the computer based on the hologram information. At the same time, the rigid connection between the object and the focussing optics elegantly solves the problem of vibration induced jitter that plays an enormous role at the nanometre scale.

Nanoscale Friction: High Energy Losses in the Vicinity of Charge Density Waves

Nanoscale Friction: High Energy Losses in the Vicinity of Charge Density Waves

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.
