DNA 'origami' takes flight in emerging field of nano machines

Just as the steam engine set the stage for the Industrial Revolution, and micro transistors sparked the digital age, nanoscale devices made from DNA are opening up a new era in bio-medical research and materials science.

Brain-computer interfaces without the mess

It sounds like science fiction: controlling electronic devices with brain waves. But researchers have developed a new type of electroencephalogram (EEG) electrode that can do just that, without the sticky gel required for ...

Modeling a model nanoparticle

Metal nanoparticles have a wide range of applications, from medicine to catalysis, from energy to the environment. But the fundamentals of adsorption—the process allowing molecules to bind as a layer to a solid surface—in ...

The perfect atomic-scale sieve

Graphene is perfectly selective to protons and blocks even smallest ions like chlorine, University of Manchester research shows. This result will be important for the development of graphene-based membranes for applications ...

Scientists develop DNA microcapsules with built-in ion channels

A Research group led by Tokyo Tech reports a way of constructing DNA-based microcapsules that hold great promise for the development of new functional materials and devices (Figure 1). They showed that tiny pores on the surface ...

Scientists create fully electronic 2-D spin transistors

Physicists from the University of Groningen constructed a two-dimensional spin transistor, in which spin currents were generated by an electric current through graphene. A monolayer of a transition metal dichalcogenide (TMD) ...

Diamonds are forever: New foundation for nanostructures

Devices smaller than the width of a human hair are key to technologies for drug delivery, semiconductors, and fuel production. But current methods for fabricating these micro- and nanostructures can be expensive and wasteful.

Nanoantennas help detectors see more heat, less noise

Sandia National Laboratories researchers have developed tiny, gold antennas to help cameras and sensors that "see" heat deliver clearer pictures of thermal infrared radiation for everything from stars and galaxies to people, ...

Catch-22 in graphene based molecular devices resolved

The conductivity of Graphene has made it a target for many researchers seeking to exploit it to create molecular scale devices and now a research team jointly led by University of Warwick and EMPA have found a way past a ...

Eco-friendly method for the synthesis of iron oxide nanoparticles

A team of scientists from Ural Federal University (Yekaterinburg), Bangladesh University of Engineering and Technology and other collaborator have published an article about a new method for the synthesis of magnetic nanoparticles. ...

Significant progress made in inverse photoconductance

Valencia University (UV) researchers have modified the photoconductance of nanoparticles of tungsten oxide (WO3) in a controlled manner. This has potential applications in photonics and optomechanics. The results have been ...
