• ITMO Researchers Discover New Type of Singularity – Exceptional Bound States in the Continuum

  A team of scientists from Russia, China, Austria, and the UK have found a new, previously considered impossible type of singularity, namely exceptional bound states in the continuum. The finding opens the door to producing energy-efficient optical transistors, modulators, and switches, as well as next-gen ultrasensitive sensors that can detect viruses and proteins more effectively. The results of the study were published in Physical Review Letters.

• ITMO Researchers Develop Gold Nanoparticle-Based Sensors for Precise Detection of Natural Antioxidants

  Scientists at ITMO University have developed multiple-use sensor substrates coated with gold nanoparticles for use in gauging the precise ratio of chlorogenic acid in natural and manufactured raw material. This natural antioxidant is widely used in the production of medical, cosmetic, and food products. The new technology should make it possible to assess the presence of chlorogenic acid in lab and field conditions alike. The results of the study were published in the Q1 publication International Journal of Molecular Sciences.

• New Method to Detect Influenza and Coronavirus Suggested at ITMO

  Researchers from ITMO University and Smorodintsev Research Institute of Influenza have suggested a multipurpose method that can detect coronavirus and influenza type A and B viruses in biological liquids. At the core of the novel method is surface-enhanced Raman spectroscopy (SERS) combined with machine learning, which help make it up to 85% accurate – meaning that it performs better than express tests (which produce false positive results in 11-48% of cases). Moreover, the new method compares favorably with PCR, too, as it takes minutes to complete. The solution is described in an article published in Biosensors.

• Cheap and Simple Method of Detection of Harmful Gases Suggested by ITMO Researchers

  Researchers from ITMO and North Ossetian State University have suggested a brand-new cheap and highly sensitive method of detecting hazardous hydrogen halides that are toxic for humans. The new perovskite nanolaser-based method is able to detect dangerous concentrations of various substances that can vary in the range of 5-500 molecules per a million of air molecules. Their suggestion may provide the basis for highly sensitive compact gas leak detectors for the food and chemical industries.
