Carbon Nanotube-Coated Electrodes Improve Brain Readouts

A research group has significantly improved the quality of brain-function measurements by coating metal neural electrodes with carbon nanotubes. Their work could potentially allow scientists to learn more about brain diseases that are based on electrical impulse malfunctions, such as Parkinson's and epilepsy.

Biochips Containing Arrays of Carbon-Nanotube Electrodes

Biochips containing arrays of nanoelectrodes based on multiwalled carbon nanotubes (MWCNTs) are being developed as means of ultrasensitive electrochemical detection of specific deoxyribonucleic acid (DNA) and messenger ribonucleic acid (mRNA) biomarkers for purposes of medical diagnosis and bioenvironmental monitoring. In mass production, these biochips could be relatively inexpensive (hence, disposable). These biochips would be integrated with computer-controlled microfluidic and microelectronic devices in automated hand-held and bench-top instruments that could be used to perform rapid in vitro genetic analyses with simplified preparation of samples.

Nanoelectrodes boost electrolysis to cut hydrogen fuel cost

QuantumSphere Inc. will report Tueday (July 15, 2008) at Semicon West in San Francisco that its nanoparticle-coated electrodes can make hydrogen an economical alternative to natural gas and gasoline.

How to Train Your Rat Neuron-Controlled Robot

By hooking up hundreds of thousands of fetal rat brain cells to a wheeled machine via an array of electrodes, the neurons' spontaneous firing can direct its motion, University of Reading scientists announced yesterday.

Carbon Nanotube Windmills Powered by 'Electron Wind'

The proposed (a) nanomotor and (b) nanodrill where the red inner CNT rotates due to an electron wind. The nanomotor is attached to gold electrodes which act as electron reservoirs while the nanodrill has one end contacted to a mercury electrode. Cred ...

Robot has biological brain

The robot, named Gordon, is not exactly an Einstein but represents a remarkable bridging of the gap between biology and technology. Gordon relies a dish with about 60 electrodes to pick up electrical signals generated by the brain cells.

Neurons Control Robot

Researchers at the University of Reading, in England, have developed a robot controlled by a biological "brain." Hundreds of thousands of rat neurons communicate via a multielectrode array--a dish with over 60 two-way electrodes that transmit signals between neurons and outside electronics--to control the movement of a wheeled robot. When the neurons receive signals that the robot is nearing an object, their output moves the wheels in an attempt to avoid obstacles. The researchers, led by neuroscientists Mark Hammond, Ben Whalley, and cyberneticist Kevin Warwick, suggest that by stimulating the neurons with different signals as the robot returns to a familiar location, they will be able to study how a brain stores data. Their goal is to eventually understand memory formation and disorders, such as Alzheimer's and Parkinson's.

Northrop Grumman To Develop Brain-Wave Binoculars

An anonymous reader writes "An AP wire reports that DARPA has granted a $6.7 million contract to Northrop Grumman to develop 'brainwave' binoculars. The binoculars will be built into a helmet, which will include EEG electrodes that will monitor the wearer's brain activity for patterns consistent with object identification/recognition. From what I can gather, the idea is that when you look at a far-off or partially obscured object without noticing it, your subconscious probably did notice it and tried, unsuccessfully, to identify it. The EEG in these binoculars would pick up on that kind of subconscious activity and draw the wearer's attention to the object in question. The goal is that these binoculars would be able to pick up on any object anywhere in the wearer's field of view, where a person can only pick up on things that he focuses b

Graphene could be used one day in large-area thin film electronics

Researchers at the Nanomaterials and Devices Group at Rutgers University have found a simple way to uniformly deposit between one and five layers of graphene from reduced GO in the form of thin films to create transistors and proof-of concept electrodes for organic photovoltaics.

Rat-brain robot alters direction of human history ... again!

The world of science and tech news is downright exuberant over the announcement of a robot controlled by the neurons of a rat brain. In case you missed it (and I don't see how you could have!), Kevin Warwick, a professor at the University of Reading, unveiled the cute little creation earlier this week. Gordon, as the would-be ratbot is known, follows the whims of 300,000 lab-grown rat neurons, whose signals are picked up by 60 electrodes and transmitted to Gordon via a Bluetooth connection.
