A DNA-based rewritable memory device

Nanowerk.com - 18 сентября, 2017 - 10:23
DNA is well known as the genetic material, but has also been used as a building block for the construction of nanoscale structures and periodic arrays. One other application is the storage of information in DNA. Such an information storage method has many advantages including longevity and ability for highly dense storage, and is more suited for archival storage of data. In new work, scientists use shape-changing DNA nanostructures for short term storage of data, where the information is 'written' in different conformations of the nanostructures. The stored data can be easily read-out using gel electrophoresis, eliminating any multi-step or costly methods.

Sensing with a twist: A new kind of optical nanosensor uses torque for signal processing

ScienceDaily.com: Nanotechnology News - 16 сентября, 2017 - 15:01
As electronic devices get smaller, their ability to provide precise, chip-based sensing of dynamic physical properties such as motion become challenging to develop. An international group of researchers have put a literal twist on this challenge, demonstrating a new nanoscale optomechanical resonator that can detect torsional motion at near state-of-the-art sensitivity. Their resonator, into which they couple light, also demonstrates torsional frequency mixing, a novel ability to impact optical energies using mechanical motions.

Self-healing materials are able to repair autonomously defects, such as scratches, cracks or dents, and resume their original shape. For this purpose, they must be composed of several components whose combined properties result in the desired characteristics. Scientists have now discovered that also tiny particles of pure gold have surprising self-healing capacities.
