Study: UK and U.S. View Nanotech Positively

Study: UK and U.S. View Nanotech Positively Ordinary people in the U.S. and the UK alike hold positive views of nanotechnology and its promise for the future, say the results of focus groups held in both countries. Interestingly, participants seemed more comfortable with energy applications than with health applications, which contradicts an earlier study that indicated the public was more comfortable with health applications. It could be that the focus on energy and gas prices during spring to summer 2008 drove the enthusiasm for nanotech as an energy answer. It could also be that the results of the study depend on who you ask and how you ask them. You decide.

Neural Prosthetics from Nanotubes?

Neural Prosthetics from Nanotubes? Carbon nanotubes form tight bonds with the membranes of neural cells, improving neuron responsiveness by potentially creating electrical shortcuts between the distal and proximal elements. The performance raises the prospect of neuroprosthetics that could electrically bypass nervous system trauma or help treat diseases such as Parkinson's.

Laser Technique Images Nanotubes

Laser Technique Images Nanotubes The decrease in the electrical conductance of carbon nanotubes (CNTs) under laser irradiation can produce images of CNT transistors. Developed by Cornell University researchers, photothermal current microscopy involves scanning a laser over the sample and leveraging the relationship between starting conductance of the material and the decrease as a function of temperature. The method can be applied to single devices and arrays, as well as imaging gate control.

Electrifying Fabric Forms Sensors

Electrifying Fabric Forms Sensors An electronic yarn formed of cotton thread coated with carbon nanotubes could provide robust, wearable sensors for the future, say University of Michigan researchers. The material demonstrated charge transport of 20 Ω/cm, showing promise for devices like humidity sensors or detectors of the blood protein albumin. Applications include biomonitoring and telemedicine.

Nanoparticles Shape DNA Structures

Nanoparticles Shape DNA Structures By leveraging gold nanoparticles and the self-assembly characteristics of DNA, Arizona State University researchers have developed DNA nanotubes, rings, and spirals (see cool videos). The group formed the shapes by attaching single-stranded DNA to gold nanoparticles. The size of the nanoparticles controlled the degree of curve, and hence the configuration of the final devices. Applications include electronics and biomedicine.

Substrate Packs Nanotransistor Wallop

Substrate Packs Nanotransistor Wallop Using a low temperature technique, researchers printed a lattice of more than 20,000 nanotube transistors on a transparent substrate. The group grew the carbon nanotubes on quartz substrates, then transferred them to glass or plastic substrates already patterned with indium-tin-oxide (ITO) gate electrodes. Next, they patterned transparent source and drain electrodes to achieve flexible, transparent devices with mobilities as high as 1300 cm2/Vs.

Nanoparticles Juice Solar Cells

Nanoparticles Juice Solar Cells Adding metallic nanoparticles to photovoltaics can improve long-wavelength efficiency by a factor of 10, says this review article from the FOM Institute for Atomic and Molecular Physics. The localized plasmon resonances generated by the nanoparticles enhance light absorption. This plasmonic solar cell technique can be applied to thin-film photovoltaics or standard silicon solar cells.

Enzyme Cleans Up Toxic Tubes

Enzyme Cleans Up Toxic Tubes Amid ongoing discussion about the environmental hazards of nanotechnology, University of Pittsburgh researchers have demonstrated that a naturally occurring enzyme can biodegrade carbon nanotubes. The group used horseradish peroxidase and 40 μM hydrogen peroxide solution at 4 degrees C to degrade the structures of raw nanotubes over the course of weeks.

Centrifuge Separates Carbon Nanotubes

Centrifuge Separates Carbon Nanotubes A new technique developed at Northwestern University can separate double-walled carbon nanotubes (CNTs) from the single-walled and multi-walled forms, showing promise for industrial manufacturing. Called density gradient ultracentrifugation, the method leverages the buoyant density of the various forms of CNTs to produce samples highly enriched with double-walled nanotubes. The group first puts the unsorted CNTs in water with surfactants, then subjects the mixture to centrifugation, which separates out the longer, heavier double-walled form.
