Laser trapping faux atoms creates “super MRI” method

A new technique, similar to the MRI but with a much higher resolution and sensitivity, uses artificial atoms to scan individual cells. The findings could revolutionize the field of medical imaging. Researchers from the Institute of Photonic Sciences (ICFO), in collaboration with the Spanish National Research Council and Macquarie University in Australia, created the “super MRI” method using artificial atoms – diamond nanoparticles doped with nitrogen impurity – to probe very weak magnetic fields such as those generated in some biological molecules. ...Read full article

    laser trapping
    A technique for confining atoms, molecules or small particles within one or more laser beams. This can be accomplished through the use of a single focused beam or multiple intersecting beams. With a single focused beam, the matter is confined to the laser beam's focal area. In the case of multiple intersecting beams, the matter is confined to the area of intersection because of the combined cooling effect of the beams. Also called optical trapping.
