• 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.

• Metaphotonics Review by ITMO Scientists Among Top 1% Most Cited Papers

  A publication by researchers from ITMO and the Australian National University is among the top 1% of the most cited papers on optics according to the bibliometric system Web of Science (WoS). The paper reviews applications of machine learning and AI in metaphotonics, a new subject field that may pave the way for a whole new class of next-gen devices.

• 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.

• ITMO Scientists Develop Algorithm to Predict Nanomaterials Toxicity

  Nanoparticles and nanomaterials are commonly used in diagnostics and drug delivery systems for oncological treatment. However, in order to be used safely, such materials have to be checked for toxicity. Students from ITMO University have developed an algorithm that can quickly predict a material’s toxicity, with fewer experiments needed to perform the task. Their study was published in Small.

• Reusable Sensor for Early Detection of Kidney Stones Developed at ITMO

  Researchers from ITMO’s Infochemistry Scientific Center have created a biosensor that can quickly detect micromolar concentrations of uric acid, thus helping diagnose and treat urolithiasis (or kidney stones) at early stages. The results of the study were featured in Polymers.

• Cheap and Simple Method of Detection of Harmful Gases Suggested by ITMO Researchers

  Researchers from ITMO and North Ossetian State University have suggested a brand-new cheap and highly sensitive method of detecting hazardous hydrogen halides that are toxic for humans. The new perovskite nanolaser-based method is able to detect dangerous concentrations of various substances that can vary in the range of 5-500 molecules per a million of air molecules. Their suggestion may provide the basis for highly sensitive compact gas leak detectors for the food and chemical industries.

• Researchers from ITMO Discover New Photonic Properties of Dielectric Resonators

  We live in a world powered by resonance: there are resonant antennas in our smartphones, and microwaves heat up our food using resonant absorption of electromagnetic radiation by water molecules. Even bridges and skyscrapers remain intact because they were designed to account for the resonance-based nature of various phenomena, such as earthquakes. It is no wonder then that dielectric micro- and nanoresonators are expected to bring about the age of optics, when all electronic devices will be replaced with optical ones. Recently, scientists from ITMO University have contributed to this field by demonstrating new photonic properties of resonators, which make it possible to control their parameters in sensors, detectors, and antennas for different devices. Their study was published in Materials Today.
