ITMO Researchers Solve Mystery of Ultrafine Plasmonic Particles
Researchers from ITMO University and the Krasnoyarsk Science Center of the Siberian Branch of the Russian Academy of Sciences (SB RAS) have advanced the theory of light absorption in ultrafine plasmonic nanoparticles. This breakthrough enhances our understanding of nanomaterials' behavior, improves techniques for targeting and destroying cancer cells, and opens up avenues to new areas of research, including quantum plasmonics. The findings were published in Nanophotonics.

New Composite for Ultrafast Durable Sensors Developed at ITMO
Researchers from ITMO and Almazov National Medical Research Centre have created a new metal-organic framework-based material that can be used to make fast-acting, durable sensors for detecting water and toxic molecules. The structure, described in an article in Materials Horizons, can instantaneously detect changes in humidity and identify dimethylformamide, a dangerous compound often used in production.

Classification From ITMO To Help AI Generate Random Noise on Request
Random noise is useful for generating truly random numbers, such as for stronger passwords and data protection, but it’s also what helps reconstruct full-scale images obtained from small cameras placed within the body during medical screenings. Using machine learning and fractal analysis methods, researchers from ITMO University have studied a source of random noise – the textures inside a layer of liquid crystal – and created a classification based on the analysis of large- and small-scale fractal dimensions. Using this data, it's possible to train a neural network to select the parameters for random noise generation, adjusting it for various purposes. The results of the study have been published in Journal of Molecular Liquids.

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.
