Nano-imaging sheds light on how anti-cancer drug Taxol works

Through a combination of high-resolution cryo-electron microscopy (cryo-EM) and new methodology for image analysis and structure interpretation, researchers have produced images of microtubule assembly and disassembly at the unprecedented resolution of 5 angstroms. Among other insights, these observations provide the first explanation of Taxol's success as a cancer chemotherapy agent.

AFM systems take a tip from nanowires

In response to requests from the semiconductor industry, researchers have demonstrated that atomic force microscope (AFM) probe tips made from its near-perfect gallium nitride nanowires are superior in many respects to standard silicon or platinum tips in measurements of critical importance to microchip fabrication, nanobiotechnology, and other endeavors.

Flatland optics with graphene

Researchers introduced a platform technology based on optical antennas for trapping and controlling light with the one-atom-thick material graphene. The experiments show that the dramatically squeezed graphene-guided light can be focused and bent, following the fundamental principles of conventional optics.
