Abstract

A new optical tweezer technology, based on optical antennas. Optical antennas are metallic nanostructures that, when illuminated at their resonant wavelength, generate enhanced optical fields with subwavelength spatial extent. The trapping of single virus particles using optical antennas with milliwatt laser powers, in volumes with dimensions of tens of nanometers. This represents a reduction in the necessary laser power by -2-3 orders of magnitude. The spatial resolution provided by the antennas will enable nanostructures to be manipulated in a highly precise manner. Optical antennas remove the need for costly objective lenses used in conventional tweezers to provide the gradient forces necessary for stable trapping. Traps can be produced on a chip by high-resolution lithography, enabling microsystems with thousands of traps.
