• ITMO Physicists Suggest Method for Mass Production of Metal-Organic Frameworks for Gas Sensors

  The detection of harmful gasses during production is made possible with gas sensors. A promising method of manufacturing these devices involves 2D metal-organic frameworks (2D MOFs). These are special porous hybrid materials with features that make them excellent sensors. Scientists from ITMO University have suggested a new production method that would result in 2D MOFs of record length and thinness – not only in lab conditions, but on industrial scale, too.

• Researchers Develop New Selective Anti-Cancer Compounds

  In collaboration, researchers from two Russian universities have developed compounds that trigger programmable death in cancer cells and tested their efficiency on cervical tumor samples. The new compounds do not affect healthy cells, their toxicity being eight times lower than that of doxorubicin, a commonly used cancer treatment. This means that in the future, treatments using the new compound may help avoid the common side effects of chemotherapy.

• ITMO Scientists Suggest New Synthesis Method For Nanoparticles Used in Cancer Treatment and Diagnostics

  Researchers from ITMO’s ChemBio Cluster have suggested a new way of synthesizing magnetic nanoparticles for cancer treatment and diagnostics. Thanks to machine learning at the core of the new approach, the scientists can quickly select the properties of nanoparticles for efficient MRI diagnostics and hyperthermia treatment. With the new method, the synthesis of a single nanoparticle takes just a few seconds – compared to the hours required in the conventional experimental approach. The method was described in a paper published in Small.

• Bringing Quantum Tech Closer: Researchers from ITMO and Ludwig Maximilian University Examine New Approach to 2D Heterostructures

  In a paper published in Nature Nanotechnology, the collaborators from ITMO and Ludwig Maximilian University of Munich describe a new method for producing two-dimensional heterostructures. The approach is based on the so-called moiré effect, achieved when two layers are stacked at a certain angle. The resulting patterns demonstrate exciton states that are of scientific interest and hold a potential in terms of next-gen electronic devices, as well as quantum technologies.

• Improving Lasers: ITMO Scientists Suggest a New Way to Couple Light and Matter

  A new approach has been suggested at ITMO to enhance interaction of light and matter during metamaterials production. Compared to conventional methods, the novel approach requires less precision and relies on cheaper equipment, while producing more compact and sensitive lasers. The study was described in an article published in Nano Letters.

• A New Way to Measure Particles: ITMO Scientists Develop Electrodynamic Trap

  Physicists from ITMO University have suggested an approach that allows them to simultaneously measure several characteristics of any microparticle – their size, mass, charge, and density. In order to test this method, they placed silica microparticles in an electrodynamic trap where they moved along a specific orbit that served as an indicator of their properties. The novel method demonstrates the precision of the more conventional approaches, which means that it can find its applications in materials science, chemistry, biology, and medicine.

• ITMO Researchers Find Way to Make Packaging Cheap, Easy to Apply

  Color laser marking is a technology that helps brands protect their products by applying unique QR codes and barcodes. While the method is good at fighting counterfeiting, the process itself is rather complicated and time-consuming. But with the technology suggested by scientists from ITMO University, manufacturers can produce protective labels for a range of products, including jewelry and optical devices, in just two seconds with no expensive equipment needed. The results of the study were published in Materials Letters.

• ITMO Scientists Suggest Novel Nanoparticle-Based Cancer Treatment

  Cancer is the second most common death cause in the world, which in 2020 took the lives of nearly 10 million people – every sixth death, according to WHO. Globally, researchers are developing new, more efficient treatments for oncological diseases. Scientists from ITMO also contribute to these efforts: recently, they have come up with a universally applicable magnetic particle from zinc ferrite and manganese ferrite that can facilitate both cancer diagnostics and treatment. The new method increases the efficiency of radiotherapy by 40%, and during magnetic hyperthermia it can heat cancer cells in several seconds, while also securing less exposure for the healthy cells. This study was published in Journal of Materials Chemistry B.

• New Method to Detect Influenza and Coronavirus Suggested at ITMO

  Researchers from ITMO University and Smorodintsev Research Institute of Influenza have suggested a multipurpose method that can detect coronavirus and influenza type A and B viruses in biological liquids. At the core of the novel method is surface-enhanced Raman spectroscopy (SERS) combined with machine learning, which help make it up to 85% accurate – meaning that it performs better than express tests (which produce false positive results in 11-48% of cases). Moreover, the new method compares favorably with PCR, too, as it takes minutes to complete. The solution is described in an article published in Biosensors.
