New Technology for Drug- and Enzyme-Delivery Fluorescent Microparticles Suggested at ITMO
Researchers from ITMO, St. Petersburg Academic University and the Institute for Analytical Instrumentation of the RAS have developed a technology for producing fluorescent microparticles with nanocrystals based on silver, indium, and sulfur. Compared to traditional organic pigments, such particles are less toxic and more resistant to laser radiation. These can be used in biomedicine to visualize blood vessels from the inside, determine the blood flow, and as carriers of treatments and enzymes. The results of the study are published in ACS Omega.

ITMO and St. Petersburg School Launch Nanotechnologies Lab
Lyceum No. 150 in the Kalininsky District of St. Petersburg is now home to the new Nanotechnologies Laboratory, launched in collaboration with ITMO’s International Laboratory “Hybrid Nanostructures for Biomedicine.” At the lab, senior students will have advanced classes in physics, chemistry, and biology, learning to synthesize several types of nanoparticles. Students will then present their work at a summer school at ITMO, with members of the best teams gaining an additional five points to their Unified State Exam scores when applying to the university.

ITMO’s New Compound Disables Disease-Producing Genes 17 Times Faster Than Counterparts
Scientists from ITMO University have created a new compound – bivalent DNAzymes: these are short, connected therapeutic DNA chains. The compound has four “arms” and two cores that enable it to find the target sequence even in the complex twisted messenger RNA of a gene, then bind with this site, and cleave it. Among the solution’s possible applications are new treatments for viral, oncological, and hereditary diseases at early stages. The DNAzyme was described in a paper published in Nucleic Acids Research.

New by ITMO Scientists: Digital Service to Facilitate Artificial Enzymes for Industry and Medicine
Researchers from ITMO University have developed a web platform that is capable of predicting a nanozyme’s (artificial enzyme) capability to accelerate chemical reactions – with high accuracy and in mere seconds. Apart from being free, the platform is user-friendly, as it’s equipped with a ChatGPT-based assistant. Among its applications is the development of new cancer treatments and sensors of hazardous materials. The platform was described in a paper published in The Journal of Physical Chemistry Letters.

Minimally Invasive Method for Urethral Catheter Cleaning Suggested at ITMO
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.

ITMO Researchers Produce Magnetic Spider Silk-Based Structures for Implantology and Targeted Drug Delivery
Scientists from ITMO University have created a magnetic material capable of promoting tissue regeneration by utilizing silk of the Linothele fallax spiders, which holds promise for implantology and tissue regeneration. In the material, the silk makes up a scaffold for cell growth, while the medications, which reach the target under the influence of the magnetic field, accelerate recovery. The drug was successfully tested in vitro – and described in International Journal of Biological Macromolecules.

Researchers Develop New Selective Anti-Cancer Compounds
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 Researchers Propose New Production Method for Biosensor Nanoparticles
Physicists from ITMO’s International Research and Educational Center for Physics of Nanostructures have proposed a method of generating plasmonic chiral nanoparticles with the help of “twisted” laser radiation. The obtained structures can be used in biosensors and polarized photodetectors, detect impurities in gasses and liquids, as well as purify medications.
