Purdue researchers use enzyme to clip 'DNA wires'

...rogen atom. The Purdue researchers sliced the DNA wires with an enzyme called BamH1, one of numerous restr... the method might be used in the future to cut DNA wires of varying lengths for building electronic devices. Ivanisevic and former Purdue physics graduate s...

Researchers Discover That Microbes Can Produce Miniature Electrical Wires

...s team speculated that the pili might be miniature wires extending from the cell that would permit Geobacter to carry out its unique ability to transfer electrons outside the cell onto metals and electrodes. This was confirmed in a study in which microbiologist Gemma Ruegera teamed with physicists Mark T. ...

Stem cells' electric abilities might help their safe clinical use

...lls (ESCs). These ion channels act like electrical wires and permit ESCs, versatile cells that possess the unique ability to become all cell types of the body, to conduct and pass along electric currents. If researchers could selectively block some of these channels in implanted cells, derived from stem c...

Researchers make long DNA 'wires' for future medical and electronic devices

...terns. Ultimately, these DNA strands could act as wires in biologically based electronics and medical devi...hes on a quilt. "These are very narrow, very long wires that can be designed into patterns for molecular electronics or biosensors," Lee said. "And in our c...

New University of Toronto research a 'pore' excuse for engineering

...lent insulator that could be used to separate tiny wires inside microelectronics. "It demonstrates how creative chemistry can lead to really interesting engineering -- it's a good marriage," says Benjamin Hatton, who led the work while he was a PhD candidate working with both the Departments of Chemistry,...

Magnetism and mimicry of nature hold hope for better medicine, environmental safety

...logical fluids because the trapped air between the wires never allows for much of the fluid to come into contact with the surface," Garcia says. That is crucial to accurate analysis because it prevents the chemicals and other materials in the droplet from combining and reacting with the chemical compound...

Encoded metallic nanowires reveal bioweapons

..." of the fluorescing nanowires to be read. If only wires with stripe pattern 1 fluoresce, for example, then the sample contains anthrax spores. One particular advantage of nanowires over other antibody supports is that the tests do not take place at a surface but instead in a suspension, which makes them r...

Brain-computer link lets paralyzed patients convert thoughts into actions

...nearby neurons and transmit them through thin gold wires to a titanium pedestal that protrudes about an inch above the patient's scalp. An external cable connects the pedestal to computers, signal processors and monitors. Converting digitized intentions into meaningful action, however, is not simple. Ac...

Electric jolt triggers release of biomolecules, nanoparticles

...en sent a brief, mild pulse of electricity through wires attached to each electrode. The current caused the bond between the sulfur atoms and the gold platform to break, setting free the tethered molecule. In theory, the researchers said, this technique could be incorporated into a biocompatible implant ...

When your brain talks, your muscles don't always listen

...dure, a small needle-like electrode with four tiny wires was embedded in the muscle of an index finger of each subject. The electrode was hooked up to a computer to record the electrical impulses as they travel from neurons to the muscle fibers. As the index finger was held steady in a small harness, ea...

MU researchers to study the status of black bears in Missouri

...ve sampling technique called “hair snares,” barbed wires that remove a few of the bears’ hairs without harming the bears themselves. After collecting hair samples this summer, they will extract DNA from the hair follicles and use that DNA to estimate the number of bears, the gender ratio of male to female ...
