• ITMO Researchers Discover New Properties of Metasurfaces Thanks to Ultrashort Pulse Lasers

  A group of researchers from ITMO University, the Australian National University, and the Friedrich Schiller University Jena (Germany) has for the first time demonstrated effective generation of higher harmonics in silicon metasurfaces. This result was achieved due to resonant states with long lifetimes. The new discovery brings closer the creation of attosecond radiation sources based on semiconductor nanostructures. Ultrashort pulse lasers which earned their pioneers the Nobel Prize in Physics in 2018 make it possible to excite and explore very rapid processes in nature and matter. This opens new horizons for understanding ultrafast physics and faster information recording.

• ITMO Researchers Develop First-Ever Online Platform For Nanozyme Modeling

  Nanozymes are artificial enzymes made up of various nanoparticles. In contrast to natural enzymes, nanozymes demonstrate all the same properties while being easier to produce and work with. However, the hardest step in developing nanozyme-based drugs and diagnostic systems is modeling the necessary properties of their particles before synthesis. Researchers from ITMO’s SCAMT Institute have solved this task by developing DiZyme, the first platform in the world that predicts the catalytic activity of nanozymes.

• Fundamental Holography: ITMO Researchers Develop Method for Printing Holograms in Color

  Scientists from ITMO’s ChemBio Cluster developed a method for printing holograms in color in a project supported by the Russian Science Foundation. At the core of the method are volume Bragg gratings, special films with reflecting properties. The proposed technology is extremely simple and doesn’t require any costly equipment. At the same time it has the potential to help produce full color holograms even on a regular printer. This project is a result of collaboration with Krypten, a scientific production organization specializing in optical protection for banknotes, documents, and trademarks.

• Invisible Material: Researchers Model Metasurfaces in Hybrid Anapole Modes for the First Time

  Global trends are leaning towards miniaturization, minimalism, and portability – and that's the case for research, too. These days, metasurfaces are gaining popularity as platforms for super-thin devices equal, or sometimes superior to, their "normal-sized" counterparts. This is achieved thanks to “invisible” particles in anapole modes. Recently, these particles have revolutionized nanophotonics, but researchers from ITMO, Moscow, and Riga went even further and developed hybrid anapole modes. Their new model is more efficient than its predecessors and opens new applications for metasurfaces in optics.

• New Plant-Based Drug Testing System to Help Cut Down on Animal Testing

  In the fall of 2019, Aleksandra Predeina, then a first-year Master’s student at ITMO came to Vladimir Vinogradov, head of ITMO’s SCAMT Institute and expressed a desire to make an art & science research project. Two and a half years later, this collaboration has resulted in a unique testing system for nanopharmaceuticals that will make it possible to significantly cut down on animal testing. Read on to learn all about the scientific breakthrough born from a passion for art.

• ITMO Researchers & Collaborators Develop New Algorithm for Linking Genes and Specific Diseases

  Researchers from ITMO’s Laboratory of Genomic Diversity and the World-Class Research Centre for Personalized Medicine have developed GPrior (gene prioritizer), an algorithm that uses data from a genome-wide association study (GWAS) to identify the genes responsible for a particular disease. For this study, the group used the data on schizophrenia, coronary heart disease, and inflammatory bowel diseases to test the algorithm. Read on to learn more about GPrior’s development and prospects.
