Purdue researchers use enzyme to clip 'DNA wires'
Researchers at Purdue University have attached magnetic "nanoparticles" to DNA and then cut these "DNA wires" into pieces, offering the promise of creating low-cost, self-assembling devices for future computers. Findings are detailed in a paper published online in February in the Journal of the American Chemical Society. The paper was written by Purdue graduate student Joseph M. Kinsella...Researchers Discover That Microbes Can Produce Miniature Electrical Wires
Researchers at the University of Massachusetts Amherst have discovered a tiny biological structure that is highly electrically conductive. This breakthrough helps describe how microorganisms can clean up groundwater and produce electricity from renewable resources. It may also have applications in the emerging field of nanotechnology, which develops advanced materials and devices in extremely sma...Nanowires can detect molecular signs of cancer, scientists find
Use of minuscule devices to spot cancer markers could lead to ultra-powerful new diagnostics Harvard University researchers have found that molecular markers indicating the presence of cancer in the body are readily detected in blood scanned by special arrays of silicon nanowires -- even when these cancer markers constitute only one hundred-billionth of the protein present in a drop of bl...Researchers make long DNA 'wires' for future medical and electronic devices
Ohio State University researchers have invented a process for uncoiling long strands of DNA and forming them into precise patterns. In the early online edition of the Proceedings of th...Encoded metallic nanowires reveal bioweapons
When dangerous infectious diseases or biological weapons are suspected, fast help is required. The first step is a reliable, sensitive, and unambiguous, yet also fast and simple, identification of the pathogen; preferably, this test should be carried out on the spot, not in a laboratory. Portable miniature biodetection systems that can detect multiple pathogens simultaneously would be ideal for t...Motorola Canopy Wires Indian Reservations
SCHAUMBURG, Ill. Though electricity and telephones dont even exist at many of their residences, tribal communities and colleges are the next highly underserved segment to be wired by...
