Nanoscale magnetic traps

We show that nanofabricated magnetic textures allow the trapping and manipulation of nanosize diamagnetic systems, such as carbon nanotubes, proteins and membranes as well as cold atoms. The latter can have temperatures as high as 1 K. Magnetic textures which can be used as traps, include films, dots and nanowires, both single and in arrays. Manipulation with trapped nanoparticles/atoms is possible by using external magnetic fields. We also briefly discuss prospects for magnetic traps at the micron scale.
