Using molecules of DNA like an architectural scaffold, scientists have developed a 3-D artificial enzyme cascade that mimics an important biochemical pathway that could prove important for future biomedical and energy applications.
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.
Researchers have succeeded in measuring a previously unknown but essential property - thermal conductivity - of an ultra-thin material that is expected to play a major role in the fast-emerging field of nanoelectronics.
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.
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.
Biologists and doctors rely heavily on incubators and microscopes. Now the Fraunhofer Institute for Biomedical Engineering IBMT has come up with a novel solution that combines the functions of both these tools in a compact and extremely small-scale system.
Yang Xiang, PhD, assistant professor of neurobiology, has received a three-year, $900,000 grant from the Human Frontiers Science Program to lead an international team of scientists in the development and implementation of a new optogenetic platform that can remotely activate neurons inside a free-moving organism.
Dr. Richard Berry of CelluForce has been named the first recipient of TAPPI's International Nanotechnology Division's Technical Award. This award recognizes outstanding accomplishments or contributions which have advanced the responsible and sustainable production and use of renewable nanomaterials
Researchers propose a configuration consisting of single plasmonic nanoshell and fluorescent emitters to achieve highly enhanced two-photon fluorescence by the dipolar and quadrupolar modes simultaneously. The hybrid nanocomposite would be a promising candidate as versatile TPF biolabels for imaging applications.
