• Scientists Invent Method of Catching Bacteria with ‘Photonic Hook’

  An international team of physicists has discovered a new type of curved light beams, dubbed a “photonic hook”. Photonic hooks are unique, as their radius of curvature is two times smaller than their wavelength. This is the first time that such a small curvature radius of electromagnetic waves has been recorded. A photonic hook can be used to improve the resolution of optical scanning systems, as well as to control the movement of nanoparticles, individual cells, viruses or bacteria. Results of this research were published in Optics Letters and Scientific Reports.
