Release date: 2018-05-22 Scientists from the Tomsk Polytechnic University in Russia, the St. Petersburg State University of Information Technology and Optics, the National University of Tomsk and the University of Bangor in the United Kingdom, and Ben Gurion University in Israel have collaborated to turn light into a "photon hook". Move tiny objects and help get super-high resolution images. As early as 2004, scientists showed that in the case of particle size and specific refractive index, the internal focus on the surface of the particle shadow moves to its edge, forming a highly localized electromagnetic field. This "photon jet" has a typical lateral dimension (less than the limit of the diffraction of the light wave), so that it can achieve ultra high resolution. This time, the research team successfully obtained a new type of curved beam "photon hook". Unlike light that requires cumbersome and complex equipment, the "photon hook" is available only with lasers and ordinary glass nanoparticles. An interesting application of "photon hooks" is to allow the movement of nanoparticles and tiny objects (such as bacteria) under light pressure. Igor Minin, a professor of electrical engineering at Tomsk Polytechnic University, points out that “this is very promising for areas where biology, medicine, and the creation of new materials must be controlled.†Such rays are expected to be used in the study of microbes and objects in the nanoworld, and the manipulation of these objects has been greatly hindered.
