• Highly Efficient & Eco-Friendly Sorbent for Wastewater Treatment Developed at ITMO University

  Researchers from ITMO University developed an affordable hybrid sorbent that efficiently removes ions of cobalt and lead from water, making it safe for both people and the environment. Unlike its analogs, the developed sorbent copes with pollution in high-acidity and -temperature water and can be regenerated and used again for up to three times after first use. The findings of the study were reported in Chemical Engineering Journal.

• Researchers Explain: All About Carbon Dots And Their Medical Applications

  Carbon nanoparticles (or carbon dots) are a recent and lucky discovery that has managed to become one of the most popular scientific trends of the last 15 years. Their biocompatibility and solubility, among other properties, make them highly useful in diagnostics and therapy of some of the most severe conditions, as well as in biosensing, bioimaging, environmental monitoring, optoelectronics, and other fields. We caught up with Elena Ushakova, the head of the Laboratory of Light-Emitting Carbon Quantum Nanostructures and PI of the Functionalized Carbon Nanoparticles group, to ask her all about carbon dots, their synthesis, and the promise they hold.

• ITMO Scientists Create Ultra-Broadband Carbon Dots With Biomedical Applications

  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.

• Researchers Present New Synthesis Method for Optically Active Carbon Nanodots

  One of the most remarkable carbon-based nanomaterials are luminescent carbon dots, the physical and chemical properties of which are easy to control. Thanks to their low toxicity, these particles are said to possess great potential in the fields of biology and medicine. Carbon dots are made from organic substances; if their precursor contains a chiral center, the resulting nanoparticles will be chiral, too. These particles have various application prospects, including in medical diagnostics. Researchers from ITMO University and St. Petersburg State University, in collaboration with their international colleagues, have developed a new way to synthesize such nanoparticles with stable optical properties.

• 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.
