NEW TECHNIQUE INTRODUCING FOREIGN ATOMS IN OPTICAL TRAPPING ALLOWS GREATER MANIPULATION OF NANOPARTICLES

Press/Media: Research

Description

Macquarie University researchers have demonstrated a new technique exploiting the presence of foreign atoms within a diamond crystal, using light to affect the motion of the entire nanoparticle – opening the door to applying powerful quantum technologies to the manipulation of ultrasmall nanoparticles and an unprecedented degree of control at the nanoscale.

Subject

The research, published in Nature Physics, measured the force on nanoscale diamond crystals (which are as small as one thousandth of the breadth of a human hair) that were immersed in water and optically trapped by a tightly focused laser beam-optical tweezers.
