• ITMO Physicists Twist Electrons for Particle Accelerator Experiments

  Researchers from ITMO University are the first to have found a way to twist electrons with a laser beam, opening up a path towards experiments with twisted electrons in particle colliders – a feat previously considered impossible. The discovery will make it possible to learn more about the structure and behavior of protons and neutrons that make up atom nuclei, as well as look into the nature of quarks, some of the smallest known matter particles. The results of the study are described in a paper published in Physical Review A.

• More Lung Cancer Cases Discovered Thanks to Computer Tomography

  In the late 2010s, there was a surge in lung cancer incidence in Russia – however, there wasn’t a related rise in death rate. According to a team of researchers from ITMO headed by oncoepidemiologist Anton Barchuk, this can be explained by the spread of computer tomography for screening and diagnostics. Their study was published in Cancer Epidemiology.

• ITMO Physicists Develop Multifunctional Material for Thermal Melanoma Therapy

  Researchers at ITMO have suggested a quick and simple method to synthesize gold plasmonic nanodiamonds – these hybrid materials can find their application in photothermal therapy of melanoma. The new material can perform two functions: heat up a tumor and measure its temperature. In vitro experiments demonstrated that once plasmonic nanodiamonds were introduced into a tumor and heated, the tumor’s growth slowed down by 65.22%. The results of the study were described in Nanophotonics.

• ITMO Researchers Discover Crystals That Imitate Brain Cell Activity

  Scientists from ITMO University have discovered that when subjected to laser pulses, hybrid crystals behave like neurons in the brain: their reaction to light is analogous to that of neurons to triggers. Such crystals can serve as a basis for devices that work as biological neural networks – thus making it possible to train artificial neural networks more quickly and efficiently. The suggested crystals are made from harmless domestically made materials and are easy to manufacture. The results of the study were described in Communication Materials (part of the Nature journal family).

• Teamwork and Business Communications: ITMO Researchers Name Most Wanted Soft Skills

  Researchers from ITMO have conducted a large-scale study on the demand for soft skills among employers. The authors have analyzed over 67,000 job listings and conducted surveys and in-depth interviews with employers and ITMO students. Among the most important competencies, representatives of businesses have named the ability to work in a team and to establish communications. Findings of the study have been published in Nature.

• First in the World: ITMO Researchers Train DNA Constructs to Detect Cancer Cells Based on Cancer Marker Concentration

  Researchers from ITMO University have developed DNA constructs based on antisense oligonucleotides that can detect different cancer marker concentrations in cells. Thanks to this capability, the DNA constructs activate only in cancer cells with high concentrations of cancer markers, cleaving the RNAs of genes responsible for the cells’ viability. At the same time, healthy cells, even with several copies of cancer markers inside, remain untouched. With this solution, target cancer therapy will become more accurate, efficient, and safe. The new DNA constructs were described in a paper published in Chemical Communications.

• ITMO’s New Compound Disables Disease-Producing Genes 17 Times Faster Than Counterparts

  Scientists from ITMO University have created a new compound – bivalent DNAzymes: these are short, connected therapeutic DNA chains. The compound has four “arms” and two cores that enable it to find the target sequence even in the complex twisted messenger RNA of a gene, then bind with this site, and cleave it. Among the solution’s possible applications are new treatments for viral, oncological, and hereditary diseases at early stages. The DNAzyme was described in a paper published in Nucleic Acids Research.

• New by ITMO Scientists: Digital Service to Facilitate Artificial Enzymes for Industry and Medicine

  Researchers from ITMO University have developed a web platform that is capable of predicting a nanozyme’s (artificial enzyme) capability to accelerate chemical reactions – with high accuracy and in mere seconds. Apart from being free, the platform is user-friendly, as it’s equipped with a ChatGPT-based assistant. Among its applications is the development of new cancer treatments and sensors of hazardous materials. The platform was described in a paper published in The Journal of Physical Chemistry Letters.

• ITMO Researchers Use Hybrid Crystal to Enable Simultaneous Grayscale and Color Direct Laser Writing

  With the new material suggested by ITMO physicists, it will be possible to embed grayscale images into color ones during direct laser writing. The researchers were the first to use metal-organic frameworks for the purpose; these are optically transparent materials that can transform laser radiation. When subjected to it, the material’s structure changes, with color defects formed inside. Each such defect has a unique scattering spectrum, making metal-organic frameworks useful in producing uncloneable anti-counterfeit trademarks. The material is described in a paper published in Advanced Functional Materials.

• ITMO Experts Confirm: Electrical Cardioversion Safe to Conduct at Smaller Clinics

  Researchers from ITMO University have demonstrated that electrical cardioversion, a procedure that helps “reset” an abnormal heart rhythm, can be safely and effectively conducted at community hospitals to treat atrial fibrillation. A paper describing the results of the study was published in BMC Cardiovascular Disorders.
