• Researchers Design New Synthesis Method for Carbon Nanodots With Potential Applications in Biomedicine

  Scientists from ITMO University, St. Petersburg State University, TU Dresden, Ioffe Institute, and City University of Hong Kong have devised water-soluble carbon nanodots that demonstrate efficient luminescence in the long wavelength spectral region. The researchers also managed to achieve the highest possible photoluminescence quantum yield reported so far for carbon nanodots emitting in the near-infrared spectral region. The developed nanoparticles can be used as non-toxic fluorescent probes for bioimaging. Read on to learn more about the study and its findings.

• Russian Researchers Suggest Innovative Approach to Production of Microfluidic Modules

  Scientists from ITMO University and the P.N. Lebedev Physical Institute have developed a unique production method for microfluidic modules based on composites of metals and polymers. Upon contact with a module, droplets of liquid flow towards the areas with the smallest wetting angle. Such modules can significantly facilitate the production of biochips, sensors, and medical express tests.

• ITMO Researchers Discover New Properties of Metasurfaces Thanks to Ultrashort Pulse Lasers

  A group of researchers from ITMO University, the Australian National University, and the Friedrich Schiller University Jena (Germany) has for the first time demonstrated effective generation of higher harmonics in silicon metasurfaces. This result was achieved due to resonant states with long lifetimes. The new discovery brings closer the creation of attosecond radiation sources based on semiconductor nanostructures. Ultrashort pulse lasers which earned their pioneers the Nobel Prize in Physics in 2018 make it possible to excite and explore very rapid processes in nature and matter. This opens new horizons for understanding ultrafast physics and faster information recording.

• ITMO Physicists Prove Feasibility of Non-Radiating States in Compact Acoustic Resonators: New Discovery Will Benefit Development of Acoustic Antennas and Sensors

  Researchers from ITMO University’s Faculty of Physics have succeeded in disproving a non-existence theorem which states that oscillations in open resonance systems must fade out by radiating energy into the surrounding medium. The physicists were able to calculate the shapes of acoustic resonators for which this theorem would not apply. In the resulting system, the energy of oscillations does not radiate into the surrounding space and remains within the resonator. Results of this research will facilitate the development of acoustic antennas and sensors.

• The Future of MRI: ITMO Researchers Develop New Ways to Acquire and Analyze MR Images

  Last year, ITMO’s International Laboratory of Applied Radioengineering was successfully selected for a Megagrant for research into the development of magnetic resonance imaging (MRI). Their goal is to make this method more efficient, convenient, and safe. This project entails the development of new devices as well as methods of producing and analyzing MR images that will help clinicians make their diagnoses swiftly and accurately. David Bendahan, a leading French scientist and one of the heads of the project, told us about the milestones achieved in the past year and the challenges of communicating with clinicians.
