• ITMO Researchers Explore Direct Laser Writing of Nanolattices

  Researchers from ITMO’s Faculty of Nanoelectronics together with their colleagues from the Lebedev Physical Institute, D. Mendeleev University of Chemical Technology of Russia, and the National Research Nuclear University MEPhI have conducted a study that showed that nanolattices possess high spectral selectivity. Their layers can be used as color filters for specific wavelength ranges, and one glass plate can contain records of up to six layers. Using this technology, the scientists were able to implement dispersive birefringent filters, which have multiple applications. For instance, they can be used to create AR/VR color displays or novel biochemical sensors for bacterial analysis.

• New Optical Biosensor Can Diagnose Infections in Few Seconds

  Russian scientists have developed a new laser technology for fabricating novel optical biosensors that are capable of identifying infectious diseases in seconds. The device reveals harmful bacteria and viruses by means of infrared light and can find wide applications in large transport hubs, such as airports, which require constant monitoring of massive passenger flows. The study was published in Laser Physics Letters.
