2018: Obtained nanorobots to create nanorobots and agents for targeted drug delivery
Scientists at the Far Eastern Federal University (FEFU), in collaboration with colleagues from Koryo University (Republic of Korea), for the first time received cobalt and iron detergents with a set of unique magnetic properties and the ability to maintain elasticity. This was reported to Zdrav.Expert on November 9, 2018 by representatives of FEFU. According to scientists, it is possible to use spotters to create nanorobots, nanosensors, new types of memory and agents for targeted drug delivery, including for anti-cancer therapy. An article about this is published in the scientific journal Nanoscale.
As explained by Zdrav.Expert in FEFU, the spotters are unusual objects discovered several years ago, their magnetic properties have not previously been specifically investigated. One of the reasons is the difficulty of obtaining structures of such a small size: samples of nanowires have wires with a diameter of about 50 nanometers, which corresponds to a chain of only 200 atoms.
 | During the experiments, for the first time we received cobalt and iron detergents and studied their magnetic properties in detail, "said Alexander Samardak, associate professor of computer systems at the School of Natural Sciences of FEFU. It turned out that these chiral spiral-like nano-objects, when interacting with magnetic fields, exhibit processes of magnetization different from cylindrical nanowires. This can be used to control them more efficiently with magnetic fields. |  |
As a scientist at FEFU said, nano-springs have almost the same mechanical properties as macro-springs. All this opens up great opportunities for the use of nanopowders in nanotechnology.
| | Nanopowders are unique objects with remarkable physical properties. This makes them promising for new types of data storage devices, nanoelectromechanical systems and biomedical use. Such materials can be used to create nanomotors, rapid testing systems for protein molecules, capsules for transferring molecular compounds and many other useful devices, "said Alexei Ognev, head of the laboratory of film technologies at the Department of Physics of Low-Size Structures of the FEFU School of Natural Sciences. | |
The work was carried out as part of the priority scientific project of FEFU "Materials" based on the laboratory of film technologies in collaboration with colleagues from Koryo University. The study included young scientists of the FEFU School of Natural Sciences - graduate student Alexei Samardak and associate professor Alexander Davydenko. The Materials scientific project of the Far Eastern Federal University brings together talented young physicists, chemists, biologists and materials scientists. They have already developed a type of optical ceramics for ground and space optical communications, a refractory material with a record melting point and a number of other promising projects.
