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.
Health and safety concerns associated with the use of nanomaterials warrant precautionary measures, but few state agencies are equipped with the knowledge needed for oversight and regulation of the use nanomaterials, minute particles of matter considerably smaller than the width of a human hair, according to a Southeastern Louisiana University occupational health and safety specialist.
Scientists from Singapore's Institute of Materials Research and Engineering (IMRE) and National University of Singapore (NUS) have created a new chemical method that enables the development of a variety of tiny light conducting metal-semiconductor contacts. These light-sensitive nano-sized components could help create bioimaging labels as well as better photocatalysts used in fuel cells.
Neutron analysis of the atomic dynamics behind thermal conductivity is helping scientists at the Department of Energy's Oak Ridge National Laboratory gain a deeper understanding of how thermoelectric materials work. The analysis could spur the development of a broader range of products with the capability to transform heat to electricity.
