  • ITMO Researchers Twist Particles Using Quantum Entanglement

    Twisted particles have found their applications in many fields, such as optomechanics, biology, astrophysics, as well as quantum optics, information science, and communications, where, for instance, they can be used to increase data capacity. However, as these particles are primarily obtained through diffraction gratings, they can’t yet be used for experiments in nuclear and particle physics given the high energies of particles used in contemporary colliders. As a solution to this problem, physicists from ITMO University have suggested a method of obtaining such particles using the so-called generalized measurements, without relying on any special equipment. Their research was supported by a Russian Science Foundation grant, with its results published in The European Physical Journal C (Particles and Fields).

  • A Quiet Place: ITMO Physicists Reduce Noise Tenfold With Metamaterial Structure

    Imagine you are in a park in the bustling downtown and there is sunshine, fresh air, and… total quiet. Doesn’t feel real, does it? Researchers from ITMO University have developed a translucent vented structure that decreases noise by up to 20 dB within the spectral range of 2 to 16.5 kHz. This means that it covers 70% of the audible bandwidth. The new structure can be used to build noise-insulating barriers alongside roads or pavilions in parks.

  • ITMO Researchers Developing New Cancer Treatment Using Gold Nanoparticles and Infrared Lasers

    In recent years, oncological diseases have become one of the most wide-spread causes of death in developed countries – and despite the abundant new diagnostics and treatment methods, fighting cancer is still a challenge. Nearly all known treatments have significant side effects, while some of them are even helpless against more persistent cancer cells. One solution to this problem is photothermal therapy, on its own or in combination with other treatments. Researchers from ITMO University have suggested a new method to treat melanoma more effectively and safely using gold nanoparticles. Read on to learn more about the new method.

  • ITMO Scientists Create Method to Quickly Detect Painting Authenticity

    In collaboration with the staff of the State Russian Museum, researchers from ITMO University have developed a new method for detecting painting authenticity with infrared spectroscopy. The method will allow the museum’s experts to quickly identify a painting’s chemical compounds and the century it was created in, as was demonstrated by a test analysis performed on a copy of one of Ivan Aivazovsky’s creations. In the future, the new method will help identify the authenticity of pieces from the era of Russian avant-garde.

  • ITMO Scientists Suggest Efficient Microfluidic Synthesis for Metal-Organic Frameworks

    Nowadays, metal-organic frameworks (MOFs) are actively studied and used for cleaning and detection purposes, as well as for recording and storage of data. For the most part, they’re synthesized using conventional methods, which require lots of resources. As an alternative, scientists from ITMO’s School of Physics and Engineering suggest a quicker and more efficient method – microfluidic synthesis of metal-organic frameworks using chips. Potentially, it can be used for targeted drug delivery.

  • 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 Scientists Discover Universal Measure to Predict Protein Folding

    Researchers from ITMO’s Infochemistry Scientific Center have suggested an algorithm that can calculate a molecule’s dimensionality – whether it’s 2D, 3D, or an intermediate state. Unlike other existing methods, the new one allows scientists to identify the folding state in biomolecules and track its progress. In an article published in Royal Society Open Science, the researchers described their molecular dynamics-based method and compared it to others, such as the Monte Carlo simulation and the widely used AlphaFold algorithm.

  • ITMO Researchers Suggest All-Optical Data Processing Method Using Heating

    Metal-organiс frameworks (MOFs) are a new class of compounds that is famous for its unique properties. They have been considered a functional material for gas adsorption, industrial membranes, and catalysts; however, researchers from ITMO have gone further and decided to zone in on MOFs’ optical properties. In a recent paper, they demonstrated that thanks to MOFs’ flexibility, these properties can be changed when subjected to lasers. This new effect can pave the way for all-optical data encoding, transfer, and storage.

  • ITMO Physicists Create Unclonable Anti-Counterfeiting Silicon Labels

    Scientists from ITMO University developed unclonable anti-counterfeiting labels, which are based on silicon nanoparticles modified with a laser. It’s impossible to change the color, structure, and location of the particles: these parameters are random, which makes the label safe from counterfeiting. In order to check if it’s authentic, all you need to do is upload its picture into a special program.
