Nanopositioning breaks new record

One of the main obstacles facing nanotechnology today is the lack of effective devices for building and characterizing nanoscale structures. For the field to progress, scientists need to be able to control the position of a mechanical system with sub-nanometric accuracy over a moving range of several millimetres. A French team has now taken an important step forward in this direction with the development of a 2D nano-positioning system that can do just this. What's more, the new instrument, based on an interferometric sensor and an optoelectronics board, can be used in a standard atomic force microscope or lithography set-up.
