Electron Beam Lithography is a technique used for the patterning of optical masks for semiconductor integrated electronic circuits as well as for writing high-resolution patterns on substrates. This training session will provide an introduction to Electron Beam Nanolithography.
The intersection of nanotechnology with the field of life sciences - including its growing impact on health care through improved diagnosis, treatment and prevention of disease - was the theme of a national conference held at the University of Albany's College of Nanoscale Science and Engineering on March 19.
Researchers in London have found that nanometer size diamonds can be attached to a wide range of substrates and that they can promote the growth of neurons without the need for the complex layers of proteins normally required.
Using a system of nanofluidic channels and multicolor fluorescence microscopy, a team of investigators at Cornell University has developed a method that analyzes the binding of DNA and DNA-binding proteins known as histones at specific locations along individual DNA molecules.
Using nanoparticles designed to recognize specific sugar-binding molecules on the surfaces of cells, a team of investigators at Michigan State University has developed a process that uses magnetic resonance imaging (MRI) to unlock the sugar-based code that identifies different types of cancer and normal cells.
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.
