Nanomagnetism findings point to new computer technologies based on magnetic spin

Researchers at the U.S. Department of Energy's Argonne National Laboratory are helping to open a new frontier in electronics, to be made up of very small and very fast devices. A new discovery by this group opens a path to new computer technologies and related devices, and could drive entire industries into the future, the researchers say.

A nanoscanning platform for biological assay

A nanoscanning platform is being developed by Prof. Sang-Gook Kim at the Micro and Nano Systems Laboratory (MNSL) at MIT. The paper describes how the variable stiffness is accomplished by engaging or disengaging electrostatically actuated clutches, in addition to the discussions on many possible benefits of the in-plane scanning platform.

Development of nanoparticle libraries for biosensing

A team of researchers at the Massachusetts General Hospital has created a large library of nanoparticles, each with a different small molecule decorating its surface. They then screen this library to see if any of the nanoparticles will bind to any number of cancer cells while ignoring healthy cells.

Laser beams build and hold nanoscale structures

A form of matter held together by nothing more substantial than light has been created by physicists in the UK. The method, known as "optical binding", was used to glue together about 100 polystyrene beads ? each 400-nanometres in diameter ? in a flat two-dimensional structure.

A single molecule working as the nano scale version of the steam engine

A single molecule working as the nano scale version of the steam engine: that is the molecular motor developed by a group of UT scientists led by prof. Julius Vancso of the MESA+ Institute for Nanotechnology. Natural motor molecules, capable of converting chemical energy into movement, have been the source of inspiration for this new synthetic version: a polymer molecule that stretches and shrinks caused by redox reactions.
