Vielversprechende nanotechnologische Ansaetze aus NRW, ob in der Forschung oder auf unternehmerischer Ebene, werden in der heute erschienenen Sonderbeilage 'Nanotechnologie - Die Zukunft erfinden- in der Sueddeutschen Zeitung vorgestellt.
DNA is found in linear and closed-circular forms in cells, and as such they can serve as component for the assembly of nanostructures of technological interest. The conformations adopted by DNA molecules depend on their intrinsic characteristics and the forces that act upon them. Scientists have quantified the effects of these different factors on the shapes of DNA rings on surface.
Researchers at the Department of Chemistry at the Technical University of Munich have developed a process that enables them to monitor local movements of proteins in time frames of nanoseconds to microseconds.
A recent advance by Arizona State University researchers in developing nanowires could lead to more efficient photovoltaic cells for generating energy from sunlight, and to better light-emitting diodes (LEDs) that could replace less energy-efficient incandescent light bulbs.
A California Institute of Technology-led team of researchers and clinicians has published the first proof that a targeted nanoparticle - used as an experimental therapeutic and injected directly into a patient's bloodstream - can traffic into tumors, deliver double-stranded small interfering RNAs (siRNAs), and turn off an important cancer gene using a mechanism known as RNA interference (RNAi).
The International Space Elevator Consortium (ISEC), an independent group designed to promote standards and foster research relating to the construction of an Elevator to Space, has announced its first annual set of prizes, named after the co-inventors of the modern-day concept of the Space Elevator, Jerome Pearson and Yuri Artsutanov.
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.
