  • 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.

  • ITMO Researchers Develop First-Ever Online Platform For Nanozyme Modeling

    Nanozymes are artificial enzymes made up of various nanoparticles. In contrast to natural enzymes, nanozymes demonstrate all the same properties while being easier to produce and work with. However, the hardest step in developing nanozyme-based drugs and diagnostic systems is modeling the necessary properties of their particles before synthesis. Researchers from ITMO’s SCAMT Institute have solved this task by developing DiZyme, the first platform in the world that predicts the catalytic activity of nanozymes.
