ITMO Researchers Develop Universal System for Delivery and Release of Antitumor Drugs Using Infrared Radiation
Oleksii Peltek, a Master’s student at ITMO University’s Faculty of Physics and Engineering, and his scientific advisor Mikhail Zyuzin have presented their research in the field of cell technologies. The scientists conducted a range of experiments on targeted delivery and non-invasive release of anticancer drugs for enabling effective treatment of malignant tumors. It is planned that going forward, the smart delivery systems they developed will be tested on animal models in vivo. The research results have been recently published in a leading international journal Biomaterials Science.
A research group from St. Petersburg including ITMO University specialists demonstrated a new transparent material that can be applied to screens of portable electronic devices. This self-cleaning material can destroy all the disease-causing bacteria on its surface and can, therefore, also be used in medicine. The discovery and its methodology were published in Materials Today Communications.
An international team of scientists from Russia and the USA that includes researchers from ITMO University presented the world’s first photonic quadrupolar topological insulator. As opposed to the existing two-dimensional topological insulators, these new structures have only recently started to be researched. In the future, this research can open the way to the creation of new reliable traditional and quantum-optical devices with a higher-order topological defense, as well as topologically protected sources of classical and quantum light. The research was conducted with support from the Russian Foundation for Basic Research and published in Nature Photonics.
Scientists Describe Universal Way of Compressing and Stopping Light for Ultrafast Optical Data Transmission
An international group of scientists which includes an ITMO researcher has published in one of the world’s leading science journals a paper dedicated to the controlled change of the speed and spectrum of a light signal. In their work, the researchers summed up the data from past experiments and theoretical studies to pave the way for the creation of new devices for high-speed data transfer. The article was featured in Nature Photonics.
Nature Photonics publishes reviews of the discoveries that haven’t been written about by the Nature Publishing Group, but, according to the editors, deserve to be highlighted. Recently, an article written by the staff of ITMO University’s Laboratory of Femtosecond Optics and Femtotechnologies was featured on the list. ITMO.NEWS talked to the head of the laboratory, Anton Tsypkin, about how the discovery was made and what opportunities Nature’s acknowledgment brings.
An international research team has shown that the conversion process of natural gas into methanol depends not only on the permanent characteristics of the catalysts used but also on the properties that these catalysts exhibit in the course of the reaction. This discovery can revolutionize the oil and wood industries by introducing modern technologies, which will allow manufacturers to process waste into valuable chemical products. The article was published in ACS Catalysis.
ITMO and Moscow State University Scientists Announce an Open Call for a Joint Article Series for Frontiers in Chemistry
Several weeks ago, ITMO University hosted the international conference Mendeleev 150, which brought together chemistry researchers from all over the world. The event may be over, but the conference’s organizers are still continuing their work in the framework of the International Year of the Periodic Table, proclaimed open by the UN. To that end, ITMO’s Mikhail Kurushkin, chair of Mendeleev 150, and Lomonosov Moscow State University professor Evgeny Gudilin have announced a series of joint articles on the periodic table’s role in a number of scientific fields. The selected works will be published in a prestigious scientific journal Frontiers in Chemistry.
Researchers from ITMO University have developed a new all-purpose method for the production of metal-oxide-based upconversion aerogels doped with rare-earth elements erbium and ytterbium. The use of this method has resulted in the production of a material with an improved structure and unique luminescent properties that has potential applications in various fields from optics to medicine, including biodiagnostics. This research has been published in the Royal Society of Chemistry’s Chemical Communications.
Scientists from ITMO University proposed a new method for identifying signatures that is based on the Minkowski–Bouligand dimension. This method allows to discern an authentic signature from a forged one with high precision, and can be used for determining the authenticity of art pieces.
An international team of researchers from ITMO University and the University of Washington in St. Louis has developed a new method for determining cell types in tissue samples. The scientists identified typical signs of genes activity in different cell types and, using this as a basis, made a model capable of recognizing different cell types in mixed samples. As this approach works for all tissues, it can be used to, for example, establish how the ratio of different cell types is associated with the survival of patients with different types of cancer. The results are published in Nature Communications.
