• Researchers Develop Nanostructure for Detection of Spiral Molecules via Twisted Light

  Scientists from ITMO University, Zhejiang University, and the Ioffe Institute have developed a metasurface capable of identifying the direction of the rotation of circular polarized light waves with a near-100% accuracy. Its artificial coating reflects leftward-spun light and allows rightward-spun light through. The structure is a mere several hundred nanometers thin, allowing it to be used even in the most advanced electronic devices. The technology should accelerate medical testing, simplify the detection of spiral molecules, such as DNA, and provide new prospects for experimental physics research. Results of the study have been published in Laser & Photonics Review.

• Scientists from ITMO Discover a New Way to Create Reconfigurable Topological States of Light

  A team of researchers from ITMO University and Australian National University came up with a new concept of photonic topological structures. Localized states of light in such structures appear not due to the intentionally designed lattice geometry but rather because of spatial variation of particles' properties.

• ITMO University Scientists Found a Way to Release Drugs from Polymer Carriers in a Non-Invasive Way

  The concept is based on the interaction of resonant semiconductor iron oxide Fe2O3 nanoparticles with light. They can get heated locally by a laser and convert the absorbed light into heat. If you modify the shell of the polymer containers (capsules) that are widely used as a carriers for the delivery of bioactive compounds in cells and irradiate them with a laser, the heat will deform the capsules and the loaded compounds will be released at the desired location and time. The research was published in Laser and Photonics Reviews.

• Scientists Propose a Fully Optical Method for Near-Field Reshaping and Enhancement in Hybrid Metal-Dielectric Oligomers

  Scientists from ITMO University in collaboration with researchers from Saint Petersburg Academic University have developed a fully optical method that allows to reconfigure the properties of hybrid metal-dielectric oligomers in the near field. This offers a simpler and cheaper alternative to the existing methods of working with such structures. The use of metal-dielectric oligomers has a lot of potential for developing new data recording devices, as well as in sensor science. The research was published in Laser & Photonics Reviews.
