Researchers at the University of Basel have succeeded in building protein gates for artificial nano-vesicles that become transparent only under specific conditions. The gate responds to certain pH values, triggering a reaction and releasing active agents at the desired location. This is demonstrated in a study published in the journal Nano Letters.
Physicists from the University of Sydney, Australia, have devised a way to use diamonds to identify cancerous tumours before they become life threatening. Their findings, published today in Nature Communications, reveal how a nanoscale, synthetic version of the precious gem can light up early-stage cancers in non-toxic, non-invasive Magnetic Resonance Imaging (MRI) scans.
Lasers with a wavelength of two microns could move the boundaries of surgery and molecule detection. Researchers at EPFL have managed to generate such lasers using a simple and inexpensive method.
An accidental discovery of a 'quantum Etch-a-Sketch' may lead to the next generation of advanced computers and quantum microchips. The lab's fluorescent lights generated surprising effects with potentially important impacts -- a new way of using beams of light to draw and erase quantum-mechanical circuits.
While the cleaning of car exhausts is among the best known applications of catalytic processes, it is only the tip of the iceberg. Practically the entire chemical industry relies on catalytic reactions. Therefore, catalyst design plays a key role in improving these processes. An international team of scientists has now developed a concept, that elegantly correlates geometric and adsorption properties. They validated their approach by designing a new platinum-based catalyst for fuel cell applications.
For nearly nine years, researchers at Lund University have been working on developing implantable electrodes that can capture signals from single neurons in the brain over a long period of time -- without causing brain tissue damage. They are now one big step closer to reaching this goal, and the results are published in the scientific journal Frontiers in Neuroscience.
An exotic, swirling object with the sci-fi name of a 'magnetic skyrmion' could be the future of nanoelectronics and memory storage. Physicists at UC Davis and the National Institute of Standards and Technology have now succeeded in making magnetic skyrmions, formerly found at temperatures close to absolute zero, at room temperature.
A research team has created the exotic ring-shaped magnetic effects called skyrmions under ambient room conditions for the first time. The achievement brings skyrmions a step closer to use in real-world data storage as well as other novel magnetic and electronic technologies.
Dion Vlachos, who directs the Catalysis Center for Energy Innovation at the University of Delaware, uses computational techniques to predict how nanoscale materials will behave and recently made a surprising discovery about the structure of bimetallic catalysts. An imperfect surface may produce a better catalyst.
Researchers at the University of Arizona in Tucson have developed a prototype of a new microscope technology that could help surgeons work with a greater degree of accuracy in diagnosing cancer or performing brain surgery or other procedures. The new technology, call augmented microscopy, is reported today in the Journal of Biomedical Optics, published by SPIE, the international society for optics and photonics.
