  • Supersensitive Express COVID-19 Test Developed at ITMO

    Scientists at ITMO have created an express test with a high sensitivity nanomachine that can detect the SARS-CoV-2 virus and is suited for point-of-care or at-home use. The new nanomachine is equipped with 4 arms and special hooks that help unfold nucleic acid sequences and detect the virus more accurately. Currently, the nanomachine can detect DNA analagous to viral 80 times and viral RNA 13 times more accurately than a hookless system and in just one hour instead of three. The invention was described in an article published in Analytical Chemistry.


  • New Lab at ITMO: Using AI to Build Molecular Machines for Therapy and Diagnostics

    Generative Design of Enzymes and Aptamers – that is the name of a new laboratory just opened at ITMO, where researchers will develop AI-based tools for creating molecular machines. These are nanodevices that can catalyze chemical reactions, selectively bind molecules, and even act as biochips. The results of such research can help develop personalized treatments and POC  (point-of-care) systems – mobile devices for medical diagnostics.


  • ITMO Researchers Developing Alternative to PCR Testing

    A joint research team from ITMO University and the University of Central Florida are working on a new type of nanosensors – the so-called DNA nanomachines (nanorobots) – that can unfold RNA and DNA structures to identify pathogen-specific sequences. Unlike PCR tests, the new testing method does not require expensive equipment and special conditions and can thus be performed outside laboratories. Here is what you need to know about the novel diagnostics method. 


  • How and Why Do Scientists Create Nanorobots?

    We can often read about nanorobots in various scientific articles. They are said to be one of the most promising tools to combat serious diseases. But what are nanorobots? In this article, ITMO.NEWS joined forces with Diana Markozashvili, participant of the ITMO Fellowship and Professorship program, to answer all your questions on the topic.


  • ITMO University Scientists Create Cancer Treatment Nanomachines

    Scientists from ITMO in collaboration with their international colleagues proposed new DNA-based nanomachines that can be used for gene therapy of cancer. This new invention can greatly contribute to making the treatment of oncological diseases more effective and selective. The results were published in Angewandte Chemie.
