Optical nano-tweezers take over the control of nano-objects

As science and technology go nano, scientists search for new tools to manipulate, observe and modify the “building blocks” of matter at the nanometer scale. With this in mind, the recent publication in Nature Nanotechnology in which ICFO researchers demonstrate for the first time the ability to use near-field optical tweezers to trap a nano-size object and manipulate it in the 3 dimensions of space, is an exciting achievement. Romain Quidant, ICREA Professor and leader at ICFO of the Plasmon Nano-Optics research group comments that “this technique could revolutionize the field of nanoscience since, for the first time, we have shown that it is possible to trap, 3D manipulate and release a single nano-object without exerting any mechanical contact or other invasive action”.
