• ITMO Scientists Develop Gene Analysis Software to Combat Superbug Viruses

  Researchers from ITMO University and the Center of Physical and Chemical Medicine have developed an algorithm capable of tracking the spread of antibiotic resistance genes in gut microbiota DNA and revealed additional evidence of resistance gene transfer between different bacterial species. The method can not only contribute to the development of effective therapy schemes, but also curb the spread of superbugs. The results of the research were published in Bioinformatics journal.

• ITMO Scientists Prove Skyrmion Laser Manipulation

  In recent years the leaders of the global semiconductor industry - companies such as Intel and IBM - have faced inability to accelerate the speed of modern computing systems by increasing the density of microprocessors per unit area. This is caused by fundamental physical limitations. However, it initialized the search for new models and methods of their implementation. Electronics of the future will be based on this research. One of the fields that scientists suggested was spintronics and its subdivision - skyrmionics, which studies exotic magnetic ring formations called skyrmions. They were first obtained in a laboratory in 2010. In the future they may find use in development of more efficient memory chips. Like graphene in the field of nanomaterials, skyrmions can lead the way to go beyond 10-nanometer technological process of chip production. Researchers at ITMO University are also working in this field and have recently managed to demonstrate in theory that properties of skyrmions can be controlled using external laser radiation. The results of this work were published in the Physical Review Letters.

• New Nanoobject Construction Method Opens Road to Complex Optics

  ITMO University scientists have developed a new approach to nanoobject construction, one that provides the opportunity to study and predict how deformations and defects in the crystal lattice affect the optical properties of semiconductor nanocrystals. This model allows them to calculate both the linear and non-linear optical properties of various nanoobjects such as: nanorolls, nanorods, nanoplates and others. The method can be used to create optical materials and devices with new functionalities with uses in drug delivery, chiral exciton-based devices and chiral catalysis devices, and areas such as biosensing and spintronics. Results of this research were published in Nano Letters and used in the writing of other articles in ACS Nano.

• Optoelectronics On Quantum Dots: Review By ITMO Researchers

  Today, TV sets based on quantum dots are becoming a common thing, which means that one of the most interesting quantum technologies invented in the 1980s is being gradually introduced in our everyday life. Thanks to the development of colloid synthesis, quantum dots are now applied in many optoelectronic devices that can already compete with their regular counterparts - photovoltaic elements, LEDs, photon detectors. So, what are the key advantages of this technology, and are the new devices ready for mass production? What are the relevant issues that scientists will have to solve in the nearest future? A group of researchers from ITMO University answered these questions in a review on the new concepts and progress in studying quantum dots published in Journal of Materials Chemistry A - a title by the British Royal Society of Chemistry.

• ITMO Scientists Help Link Alzheimer’s to Lack of Energy in Immune Cells

  An international scientific team that includes scientists from ITMO University has discovered why a mutation or lack of TREM2 protein in the nervous system of immune cells increases the likelihood of developing Alzheimer’s disease. It turns out that in these cases, immune cells cease to receive nourishment and begin to “digest” themselves. The research was published in Cell journal.

• Life in World of Resonances

  Half a century ago, an Italian physicist Ugo Fano published a paper where he described a type of resonance with a distinctive asymmetrical profile which emerges as a result of an interference of two wave processes. Many years later, his research became one of the most cited articles of the 20th century. Recently, scientists from ITMO University, Ioffe Institute and the Australian National University Mikhail F. Limonov, Mikhail V. Rybin, Alexander N. Poddubny and Yuri S. Kivshar published a review of the problems and accomplishments of using the Fano effect in modern photonics in the Nature Photonics magazine. Mr. Limonov shared about the review and possible applications of the Fano resonance in an interview to ITMO.NEWS.

• International Team of Scientists Proved How Intestinal Microbiota Can Affect the Flu

  An International team of scientists from Washington University School of Medicine (USA) and ITMO University proved experimentally that intestinal microbiota in mice can influence the body’s immune response to the flu. Metabolites, which are formed in our gut, stimulate the increase of interferon which is a protein responsible for suppressing the virus’s replication. The results of the research are published in Science magazine
