• ITMO Scientists Create Ultra-Broadband Carbon Dots With Biomedical Applications

  Carbon nanodots are a new trend in science, now used in smart packaging, warranty tags and with potential applications in diagnostics and tumor visualization. However, in order to be used in biomedicine, carbon nanodots have to be made visible through the human skin. This has recently been achieved by researchers from ITMO University, the Ioffe Physical-Technical Institute, and North Ossetian State University, who synthesized nanodots with unique properties: they can radiate and absorb light in the infrared spectrum. Such newly developed dots can be used for tissue visualization in medicine. Learn more about the new carbon dots synthesis method and its practical applications in this article.

• ITMO Researchers Develop Novel Strategy to Tailor Photonic Topological Insulators

  The team of ITMO University’s frontier laboratory Probing Fundamental Physics with Topological Metamaterials have proposed a new method of engineering photonic topological structures. At its core is the manipulation of topological properties via mutual orientation of meta-atoms. In an article published by Laser & Photonics Reviews, the physicists have theoretically and experimentally demonstrated topological edge and corner states. These results should prove instrumental in making another step towards the use of topological structures in photonic meta-devices.

• ITMO Physicists Found New Way to Optimize Nanoparticles and Light Interaction

  ITMO scientists have been the first to describe new features of dielectric nanoparticles’ optical response using an improved method for electromagnetic field analysis that can take into account more complex configurations of bias currents inside the objects. These effects allow to better understand the processes in nanoparticles and adjust their behavior for more efficient light control in devices such as nanolasers or sensors. The results have been published in Laser and Photonics Reviews and selected as materials for the issue cover.
