Guest_Jim_* Posted August 20, 2015 Posted August 20, 2015 A lot of technologies are being pushed smaller and smaller all the time, to meet the desires of consumers and to enable new applications. Due to their small size though, some of these technologies, like nanoparticles, can be difficult to control. Researchers at the University of Zurich though have successfully manipulated nanoparticles in a solution, using only electrical and optical signals. To achieve this level of control, the researchers are taking advantage of the particles' electrical charges. Normally the particles would just be subject to Brownian motion, but the electrical charge means more forces can affect them. By using this, the researchers are able to control the position and orientation of the nanoparticles, enabling them to form nanostructures within the solution. This is achieved without contacting the nanoparticles and at room temperature. Potentially this discovery could have digital applications, as the nanoparticles could be used to store information. They could also be put to use in displays similar to the e-Ink displays, but with a much smaller pixel size, and thus a higher pixel density, while also speeding up response times.
