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.
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.
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.
Started by a single mutation in a cell, cancer is one of the leading causes of death worldwide that killed nearly 10 million people in 2020. In the article, Evgeniya Platonova, a Master’s student at ITMO’s SCAMT Institute, explains what cancer is and how it starts, and shares what medical advances are already helping to combat the disease.
It’s been a while since our latest digest of all things science at ITMO – so strap in for an extra-packed edition! From staggering medical breakthroughs to a whole slew of new Master’s programs, there’s plenty to get you excited about the future of research.
Carbon nanodots are a new trend in science, now used in smart packaging, warranty tags and with potential applications in diagnostics and tumor visualization. However, in order to be used in biomedicine, carbon nanodots have to be made visible through the human skin. This has recently been achieved by researchers from ITMO University, the Ioffe Physical-Technical Institute, and North Ossetian State University, who synthesized nanodots with unique properties: they can radiate and absorb light in the infrared spectrum. Such newly developed dots can be used for tissue visualization in medicine. Learn more about the new carbon dots synthesis method and its practical applications in this article.
A research team from ITMO’s ChemBio Cluster and the University of Central Florida has developed a binary antisense oligonucleotide (a short DNA molecule produced by chemical synthesis) that consists of two oligonucleotide chains. As one part of the chain targets a tumor marker and the other – a vital housekeeping gene, the technology allows scientists to target cancer cells without harming the healthy ones.
The proposed model allows researchers to understand how certain substances can influence the formation and development of bone cells. This knowledge is useful both in fundamental biological research and in the creation of new ways to prevent osteoporosis and other diseases. Moreover, the model can be used to design smart wound-healing materials.
ITMO scientists proposed a simple and affordable method for producing such nanocapsules from various metals. These particles have potential applications in catalysis and biomedicine.
