  • ITMO Scientists Develop Algorithm to Predict Nanomaterials Toxicity

    Nanoparticles and nanomaterials are commonly used in diagnostics and drug delivery systems for oncological treatment. However, in order to be used safely, such materials have to be checked for toxicity. Students from ITMO University have developed an algorithm that can quickly predict a material’s toxicity, with fewer experiments needed to perform the task. Their study was published in Small.


  • Flexible Electronics and Sensors: Researchers Develop Improved Method for Copper Micropattern Printing

    Scientists from ITMO University and the Institute of Chemistry of St. Petersburg State University have developed a more affordable and efficient method that makes printing copper micropatterns on a glass surface 100 times faster. The resulting micropatterns can be used  in various devices, such as chemical sensors, flexible electronics, and anti-theft systems.


  • Researchers Design New Synthesis Method for Carbon Nanodots With Potential Applications in Biomedicine

    Scientists from ITMO University, St. Petersburg State University, TU Dresden, Ioffe Institute, and City University of Hong Kong have devised water-soluble carbon nanodots that demonstrate efficient luminescence in the long wavelength spectral region. The researchers also managed to achieve the highest possible photoluminescence quantum yield reported so far for carbon nanodots emitting in the near-infrared spectral region. The developed nanoparticles can be used as non-toxic fluorescent probes for bioimaging. Read on to learn more about the study and its findings.


  • Contest-Winning ITMO Master’s Student on Making Science Popular

    We caught up with Dauddin Daudi, a recently-enrolled student of the Chemistry of Applied Materials Master’s program. Before coming to ITMO, he worked on a number of projects and was twice named a winner of the national contest My Country – My Russia. Speaking to ITMO.NEWS, he elaborated on the projects that brought him success and explained why he abandoned a career in the oil industry to study spiderwebs – and why science needs to be popularized not only among the public, but among scientists, too.


  • ITMO Researchers Suggest Design for Biointegrable Controlled Nanoparticles

    Scientists from ITMO University have designed a unique smart nanomaterial that can be controlled via heat: when subjected to light, the material changes both shape and color. This discovery will be beneficial to the development of non-invasive biosensors, signal systems, and non-toxic dyes. The results of the study were published in the international edition of Angewandte Chemie.


  • How Particles of Silver Darken Under the Influence of Light

    It happens during the reaction between agar, melamine, and silver nitrate. After getting dried, a layer of this mixture becomes a flexible film that can be used for the detection of dangerous chemicals on the surface of fruits and vegetables.


  • Picture of the Week: Dendritic Growth of Salt Crystals

    Such structures are used for growing cell cultures. They provide an environment for the growth of metal ions and adjust the media’s acid-alkaline balance.


  • ITMO Researchers Develop Lab-on-Chip Hardware for Detection of Substance Traces in Media

    The newly-developed elements have found a use in the detection of dangerous molecules in a given medium. Laser recording methods make it possible to integrate various functional elements within the glass chip.


  • Picture of the Week: Perovskite Inorganic Quantum Dots

    The effect that can be seen on the picture is called photoluminescence. Quantum dots made out of cesium perovskite receive ultraviolet light that gets absorbed by quantum dots and then re-emitted, but in the spectral range.


  • Scientists Suggest Using Gold Nanoparticle Metasurfaces to Determine Substance Molecular Composition

    This will make it possible to create compact devices that will accurately determine molecular composition of a liquid or gas, and help identify potentially dangerous chemical compounds. The results of the work carried out by researchers from ITMO University and Ben-Gurion University of the Negev, Israel have been published in Nanomaterials.
