With electrochemical analysis (a high sensitivity method for detecting target substances in solutions) and machine learning at its core, the new technology developed at ITMO can automatically detect the exact quantity of antibiotics in milk. Apart from protecting consumers from harmful substances, the new solution can be used to analyze other environments, such as oil (for revealing unwanted contaminants), coffee (for determining its quality), and wine (for verifying its authenticity). The technology with its underlying research was described in an article in ACS Applied Materials & Interfaces.
A team of researchers from ITMO, Chelyabinsk State University, and Southern Federal University have suggested a new minimally invasive and safe method for the cleaning of urethral catheters. The new approach involves soft magnetic robots that are nearly 100% effective at removing bacteria-containing biofilm from medical devices. Controlled remotely by a magnetic field, the robots will help prevent the spread of infections, reducing the need for frequent catheter replacement, which is a painful procedure. The new method was described in an article published in ACS Nano.
Physicists from ITMO and St. Petersburg Academic University have collaborated to develop a device that can be used as a transistor in optical computers – it can create an electric field in nanostructures without the use of any power sources. In the article published in Light: Science & Applications, the research team describes the theory behind it as well as the experiments they conducted on a nanoantenna to demonstrate the capacities of the new device.
The detection of harmful gasses during production is made possible with gas sensors. A promising method of manufacturing these devices involves 2D metal-organic frameworks (2D MOFs). These are special porous hybrid materials with features that make them excellent sensors. Scientists from ITMO University have suggested a new production method that would result in 2D MOFs of record length and thinness – not only in lab conditions, but on industrial scale, too.
In collaboration, researchers from two Russian universities have developed compounds that trigger programmable death in cancer cells and tested their efficiency on cervical tumor samples. The new compounds do not affect healthy cells, their toxicity being eight times lower than that of doxorubicin, a commonly used cancer treatment. This means that in the future, treatments using the new compound may help avoid the common side effects of chemotherapy.
ITMO Scientists Suggest New Synthesis Method For Nanoparticles Used in Cancer Treatment and Diagnostics
Researchers from ITMO’s ChemBio Cluster have suggested a new way of synthesizing magnetic nanoparticles for cancer treatment and diagnostics. Thanks to machine learning at the core of the new approach, the scientists can quickly select the properties of nanoparticles for efficient MRI diagnostics and hyperthermia treatment. With the new method, the synthesis of a single nanoparticle takes just a few seconds – compared to the hours required in the conventional experimental approach. The method was described in a paper published in Small.
Bringing Quantum Tech Closer: Researchers from ITMO and Ludwig Maximilian University Examine New Approach to 2D Heterostructures
In a paper published in Nature Nanotechnology, the collaborators from ITMO and Ludwig Maximilian University of Munich describe a new method for producing two-dimensional heterostructures. The approach is based on the so-called moiré effect, achieved when two layers are stacked at a certain angle. The resulting patterns demonstrate exciton states that are of scientific interest and hold a potential in terms of next-gen electronic devices, as well as quantum technologies.
A new approach has been suggested at ITMO to enhance interaction of light and matter during metamaterials production. Compared to conventional methods, the novel approach requires less precision and relies on cheaper equipment, while producing more compact and sensitive lasers. The study was described in an article published in Nano Letters.
Physicists from ITMO University have suggested an approach that allows them to simultaneously measure several characteristics of any microparticle – their size, mass, charge, and density. In order to test this method, they placed silica microparticles in an electrodynamic trap where they moved along a specific orbit that served as an indicator of their properties. The novel method demonstrates the precision of the more conventional approaches, which means that it can find its applications in materials science, chemistry, biology, and medicine.
A publication by researchers from ITMO and the Australian National University is among the top 1% of the most cited papers on optics according to the bibliometric system Web of Science (WoS). The paper reviews applications of machine learning and AI in metaphotonics, a new subject field that may pave the way for a whole new class of next-gen devices.
