• Researchers Use Silicon Nanoparticles For Bioimaging and Drug Delivery

  An international research team has studied a new cell visualisation and drug delivery system based on nanoparticles coated with luminescent dye molecules. Scientists have found out that the particle material and the distance between the dye and the particle’s surface affect the intensity of the luminescent signal. It turned out that silicon nanoparticles coated with dye molecules are more efficient than similar particles made of gold. Thanks to their biocompatibility, silicon particles can be used for cell visualisation and drug delivery. The research was published in Scientific Reports.

• New Blockchain-Based System Will Control Quality of Medical and Chemical Products

  Scientists from ITMO University’s international research laboratory SCAMT, together with developers from Aira and information security experts, are developing a system for end-to-end monitoring of the manufacturing of medical and chemical products. The system is based on the lab’s “Nanodoctor” – a chlorine dioxide-based drug capable of neutralizing nearly all viruses and bacteria. Among its advantages are an improved structure that prevents the accumulation of harmful substances during manufacturing, and a new quality control system based on blockchain technology. The project’s concept allows end customers to learn about each of the production stages using a QR code printed on the packaging and make sure that the process occurred without any infractions and the active ingredient content is within the stated amount.

• Scientists Develop Improved Model for Study of Zika Virus

  An international research team has developed a new animal model used to study the pathogenesis of the Zika virus. Scientists were able to make the disease develop in mice in a way that is similar to what happens in humans. The new model reflects the most dangerous manifestation of the Zika virus: infection of the fetus from a pregnant woman, which leads to developmental problems. Such an advancement was achieved due to a new, more pathogenic virus strain, as well as a specially bred group of mice with a human-like immune response. The new model paves the way for more detailed study of the Zika virus, which should result in a more effective fight against it. The research is published in Cell Host & Microbe.

• ITMO PhD Student on Doing Medical Modeling at University of Sheffield

  Can computer modeling help us solve problems of people suffering from cardiovascular diseases? Scientists from ITMO University in collaboration with colleagues from the Netherlands and the United Kingdom have been conducting research over the last few years to reduce the risk of complications after coronary stenting. These stents are special dilating frames that are placed in the coronary vessels and are designed to restore blood supply to the heart. Pavel Zun - a PhD student at ITMO University’s The High-Performance Computing Department and one of the project’s authors - spent the last month at the University of Sheffield, where he worked with biologists on a model for tissue growth inside the vessel after the stent is installed. He shared some details about the research with ITMO.NEWS and explained why design of computer models for medicine is one of today’s most promising areas of work.

• ITMO Researchers Participating in Targeted Drug Delivery Research

  Targeted delivery of medicine and genetic material to cells and tissue can be solved using micro- and nanoparticles of various types. Research in this field tends to be interdisciplinary and calls for collaboration between biologists, chemists and physicists. Mikhail Zyuzin, a postdoctoral researcher at ITMO University’s Faculty of Physics and Engineering, is working with colleagues from Russia and abroad to develop new methods of targeted drug delivery. He spoke with ITMO.NEWS about his research and working with other scientists.

• ITMO-Developed Nanoparticle Technology Helps Stop Internal Bleeding

  Scientists from ITMO University have developed magnetically-driven nanoparticles containing thrombin. A drug based on these nanoparticles can be injected intravenously and delivered straight to the site of a vascular injury to stop internal bleeding. It can accelerate local clot formation and reduce overall blood loss by up to 15 times. The nanoparticles are not toxic to humans and can potentially be used for safe treatment. The results were published in Scientific Reports.

• Chemist Artem Oganov: On Blind Spots in Chemistry and Materials of Future

  Today Artem Oganov is rightly considered one of the most famous Russian scientists of the new generation. Oganov is a theoretical crystallographer and the creator of a number of new materials – as well as methods of discovering them. A few years ago he solved the problem of predicting the crystal structure of a substance based on its chemical composition. This problem was for long considered to be unsolvable. Oganov created software capable of predicting stable chemical compounds based on a set of initial elements. His discoveries are so impressive that many consider him one of the likely candidates for the Nobel Prize in the next few years. Having worked abroad for 17 years - in England, Switzerland and the United States - at 37 he decided to return to Russia, where he became a professor of Skoltech and headed the Laboratory of Computer Design of Materials at MIPT. During an open lecture at ITMO University, Oganov spoke about his career abroad, his return home, materials of the future and creation of an evolutionary mechanism for predicting substance structures, which proves that even in well-known areas of chemistry there are still many "blind spots". Main points of the event - in this article by ITMO.NEWS.

• BIOCAD Expert: Building Teams in Innovative Businesses

  Why is it necessary to use a different approach when forming and developing teams for high-tech companies, and why don’t the methods of traditional business work? Tatiana Tangisheva, head of personnel development at the biotechnology company BIOCAD came to ITMO to conduct a workshop on the specifics of managing and working with employees in innovative companies and the top international practices. The “Team Management in Innovative Companies. Motivating Members of Creative and Intellectual Teams” workshop was held at ITMO’s Faculty of Technological Management and Innovations.
