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.
Scientists from ITMO University have developed a new method of creating holograms that makes use of a polymer nanocomposite material: the interference pattern is created by nanoparticles that move inside the material due to polymerization. The chemical process proceeds under the effect of light; as result, areas that have different optical properties emerge. According to the researchers, such holograms are a more effective method of protecting valuable documents and objects, and also a great technology for producing promotional merchandise.
Using nanoparticles for medical purposes is a promising method which remains sought-after for over 10 years. One of the most important breakthroughs in this field is optical heating of nanoparticles fixed on tumor cells. Using this method one can damage diseased cells with localized heating. To control the temperature without damaging living tissues researchers use golden particles. However, the current control methods are complicated and take lots of time. ITMO Master’s student Georgy Zograf tries to solve this problem using silicon nanoparticles. He became the first author of article devoted to the results of this study, which was published in Nano Letters.
ITMO’s International Research Center for Magnetically Controlled Nanosystems for Theranostics of Oncological and Heart Diseases opened recently. Its researchers plan to develop hybrid nanosystems for targeted drug delivery. The center will be headed by Anna Orlova, an associate professor at the Department of Natural Physics and Natural Science and Professor Yury Volkov, chair of Trinity Translational Medicine Institute. The specialists from the Institute of Experimental Medicine at the Federal Almazov North-West Medical Research Centre will also join the research team.
At ITMO's Bioengineering Center, scientists develop nanomodified polymer implants that are 100% compatible with the human organism, dissolve within several years, and even have antibacterial properties. Thanks to this technology, it might well become possible to restore limb functions even after loss of whole parts of the skeleton, which is impossible in the current state of technology. The research's results were presented by Igor Denisuk, one of the project's leaders and professor of the Department of IT in the Fuel and Energy Industry. Maya Uspenskaya, the department head, is also among the project's heads.
