Depending on whom you ask, nanoparticles are, potentially, either one of the most promising or the most perilous creations of science. These tiny objects can deliver drugs efficiently and enhance the properties of many materials, but what if they also are hazardous to your health in some way? Now, scientists at the National Institute of Standards and Technology (NIST) have found a way to manipulate nanoparticles so that questions like this can be answered.
Like an opera singer hitting a note that shatters a glass, a signal at a particular resonant frequency can concentrate energy in a material and change its properties. And as with 18th century "musical glasses," adding a little water can change the critical pitch. Echoing both phenomena, researchers at the National Institute of Standards and Technology (NIST) have demonstrated a unique fluid-tuned 'metasurface', a concept that may be useful in biomedical sensors and microwave-assisted chemistry.
A multidisciplinary research team within the Institute for Genomic Biology at the University of Illinois, Urbana-Champaign reports a FRET-based biosensor with defined sensitivity and dynamic range for imaging changes in the intracellular redox environment that appear to dictate cell fate. The FRET-based biosensors are a significant advance for routinely measuring oxidative stress in real-time. The sensor is most useful for monitoring intraorganellar glutathione potentials in the relatively high oxidative environments of ER, Golgi and lysosomes.
Graphene is the electronic miracle material of the 21st century. Until now, only sheets that were very small or of a somewhat inferior quality could be produced that were too small or not well suited for high-tech applications. Now, researchers have developed a process capable of producing a high-quality product with a single step.
The Belgian Presidency of the Council of the European Union organized a high level event on September 14, 2010, bringing together representatives of various associations, scientists, regulatory experts as well as national and European regulatory bodies, in order to review the legislative initiatives in progress with regard to nanomaterials and to establish an operational framework for the management of incidents in the short term and to achieve improved risk management in the long term.
The main objectives of this initiative are: To perform joint work or to be trained in the leading European industrial and academic research institutions; To enhance long-term collaborations within the ERA; To generate high-skilled personnel and to facilitate technology transfer.
Vacuum Expo provides a sizeable and comprehensive exhibition that involves industry leaders presenting new ideas. Delivered with a passion for vacuum technology, Vacuum Expo's remit is to provide a meeting place for users of vacuum technologies and to be a venue for education and training in the use and measurement of vacuum in general industry, in science and manufacturing.
