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.

ITMO Researchers Study the Prospects of Switching to Driverless Transport
The rapid development of driverless vehicles makes it quite possible that in the coming decades, the role of drivers in transport will gradually peter out. ITMO’s researchers decided to model a situation when all private transport in St. Petersburg is replaced by autonomous cars that work as taxis. It turned out that the amount of taxis necessary to meet the city’s transport demand is ten times less than the number of private cars in the city, the average ride through the city will take about 16 minutes, and the wait time for 85% of the rides will be less than 10 minutes. Valentina Solovyova, staff member for ITMO's “Optimal Transport Systems” Laboratory expanded on the research in an interview for ITMO.NEWS.

ITMO Scientists Study Properties of Terahertz Gauss-Bessel Beams
Scientists from ITMO University became the first to conduct a comprehensive study of the spatio-temporal and spatio-spectral properties of pulsed broadband terahertz Gauss-Bessel beams. This theoretical research looks promising in terms of practical application, as these beams can be used in wireless communications to increase data transfer speed and the number of simultaneously connected devices. The research results were published in the Scientific Reports journal.

Mining Hardware Helps Scientists Gain Insight into Silicon Nanoparticles
Researchers from ITMO University and their international colleagues have developed the first three-dimensional dynamic model of an interaction between light and silicon nanoparticles. They used a supercomputer with graphic accelerators for the calculations. Results showed that when exposed to short, intense laser pulses, silicon particles temporarily lose their symmetry and their optical properties become strongly heterogeneous. Such a change in properties depends on particle size; therefore it can be used to control light at nanoscale and in ultrafast information processing devices. The study was published in Advanced Optical Materials.

ITMO Researchers Participating in Targeted Drug Delivery Research
Targeted delivery of medicine and genetic material to cells and tissue can be solved using micro- and nanoparticles of various types. Research in this field tends to be interdisciplinary and calls for collaboration between biologists, chemists and physicists. Mikhail Zyuzin, a postdoctoral researcher at ITMO University’s Faculty of Physics and Engineering, is working with colleagues from Russia and abroad to develop new methods of targeted drug delivery. He spoke with ITMO.NEWS about his research and working with other scientists.

Science Communication at the Alexander von Humboldt Foundation
Alexandra Borisova from ITMO’s Science Communication and Outreach Office spent a year in Germany at Rhine-Waal University of Applied Sciences, one of Europe’s leading science communication centers. She was awarded a German Chancellor Fellowship (the Alexander von Humboldt Foundation) that allowed her to work on her research project on science communication in Russia. ITMO.NEWS asked Alexandra some questions about the program, her research, and about ITMO’s new European partners.

ITMO-Developed Nanoparticle Technology Helps Stop Internal Bleeding
Scientists from ITMO University have developed magnetically-driven nanoparticles containing thrombin. A drug based on these nanoparticles can be injected intravenously and delivered straight to the site of a vascular injury to stop internal bleeding. It can accelerate local clot formation and reduce overall blood loss by up to 15 times. The nanoparticles are not toxic to humans and can potentially be used for safe treatment. The results were published in Scientific Reports.

Chemist Ekaterina Skorb On International Work Experience And Prospects Of Infochemistry
In the course of her scientific career, Ekaterina Skorb has worked in four different countries. After receiving her education in Minsk, she continued with her research at Max Planck Institute in Germany where she led a research team and developed smart biomaterials. At Harvard, she worked in the team of George Whitesides, the world’s most cited chemist, on several fundamental projects, including the Origins of Life. As of now, Ekaterina Skorb is a professor at ITMO University, leading a research team in its Biochemistry Cluster. Among its key projects are creating dynamic optical materials, biochips that would allow to diagnose a wide range of diseases, and fundamental research in the field of storing information with the help of chemical systems. In an interview for ITMO.NEWS, she talked about her work in the world’s major universities and moving to Russia, key research areas, and combining chemistry with IT.

Researchers From ITMO Create First-Ever Light-Emitting Nanoantennas
Young scientists from ITMO University have developed a new type of nanoscale light sources based on halide perovskites. The nanosources are subwavelength nanoparticles which serve both as emitters and nanoantennas capable of amplifying light emission inherently without need for additional devices. Moreover, perovskites enable tuning of emission spectrum throughout a visible range by varying the composition of the material. This makes the new nanoparticles a promising platform for creating compact optoelectronic devices such as optical chips, light-emitting diodes, or sensors. The results were published in Nano Letters, one of the leading journals on nanophotonics.
