Nanoscale Topography May Help Advance High-Speed Graphene Electronics

By fabricating graphene structures atop nanometer-scale "steps" etched into silicon carbide, researchers have for the first time created a substantial electronic bandgap in the material suitable for room-temperature electronics.

Researchers Use Atomic Force Microscopy to Study Amyloid Fibrils

Researchers at ETH Zürich, EPF Lausanne and at the University of Fribourg have evidenced a basic general mechanism describing how filamentous proteins assemble into ribbon like structures, the so-called Amyloid fibrils. Combining experiments and theory, they could explain how denatured milk proteins assemble into ribbon like structures composed of up to five filaments. These findings are shining a surprisingly new light on the assembly of these proteins.

Graphite Demonstrates Negative Coefficient of Friction at Nanoscale

If you ease up on a pencil, does it slide more easily? Sure. But maybe not if the tip is sharpened down to nanoscale dimensions. A team of researchers at the National Institute of Standards and Technology (NIST) has discovered that if graphite (the material in pencil "lead") is sticky enough, as measured by a nanoscale probe, it actually becomes harder to slide a tip across the material's surface as you decrease pressure—the exact opposite of our everyday experience.

New Technique to Assemble Proteins with Nanometer Accuracy

A research team headed by LMU physicist Professor Hermann Gaub has developed a technique called Single-Molecule Cut & Paste (SMC&P) wherein an atomic force microscope (AFM)’s super sharp tip enables the pickup and deposition of single biomolecules at the designated site with nano-scale accuracy.
