To eliminate the need for invasive biopsy, and to improve upon the diagnostic sensitivity of biopsy, researchers have been working to develop non-invasive imaging techniques to identify tumor-bearing sentinel lymph nodes.
Scientists have developed a dual-purpose nanoparticle that only enters cells coated with two proteins that tumor cells use to invade healthy tissue. Once the nanoparticles accumulate in tumor cells, they become readily visible using either MRI or a standard fluorescence microscope.
Interest in 'green' innovation means not just thinking big but also very, very, very small. At least that's the way Omowunmi Sadik, director of Binghamton University's Center for Advanced Sensors and Environmental Systems, sees it. She is working to develop sensors that would detect and identify engineered nanoparticles.
There is little information, for instance, on whether pregnant women exposed to these minute particles pass them on to their unborn babies. Scientists from Empa and the University Hospital Zurich now show first results.
SNNI's 5th annual conference, GN10: Reducing principles to practice on June 16-18, 2010 in Portland, Oregon, will feature the latest developments in the design and production of greener nanomaterials, discuss and debate how to move the technology forward while developing environmentally sound products and processes, and focus on a few critical developments that will determine whether the U.S. will be a leader or a follower in this critical field.
EU-funded researchers have created the first three-dimensional (3D) invisibility cloak and used it to successfully hide a small bump on a gold surface. The findings represent a major advance in the field of transformation optics, which uses a special type of materials called 'metamaterials' that can guide and control light in new ways.
This Strategy, launched on March 18, sets out how UK Government will take action to ensure that everyone in the UK can safely benefit from the societal and economic opportunities that these technologies offer, whilst addressing the challenges that they might present.
Biozentrum researchers have now discovered that Escherichia coli bacteria harness a sophisticated chemosensory and signal transduction machinery that allows them to accurately control motor rotation, thereby adjusting their swimming velocity in response to changing environments.
These boots are made for walking ... and for powering up your cell phone? It could happen, according to a team of Princeton and Caltech scientists. They report that they have developed an innovative rubber chip that has the ability to harvest energy from motions such as walking, running, and breathing and convert it into a power source.
