Dr. Elena Zavyalova is a graduate of the Chemistry Department at Lomonosov Moscow State University in Moscow, Russia. In 2013, she earned her PhD at the same university on the topic "Study of Thrombin Inhibition by Aptameric Oligonucleotides". In 2022, she achieved the rank of Habilitatus Doctor in Chemical Sciences with a thesis on "Fundamental Aspects of Aptamer-Protein Complex Formation". Her main research interests lie in the field of DNA aptamers for proteins and small molecules, as well as the development of biosensors based on aptamers. Recent projects have focused on optimizing the structure of aptamer nucleic acids and developing aptasensors for detecting influenza A, SARS-CoV-2, and African swine fever viruses using surface-enhanced Raman spectroscopy (SERS) and electrochemical methods. An SERS-based assay for antimicrobial resistance has also been proposed for rapid microbiological testing. Additionally, sensors based on electrolyte-gated organic field-effect transistors (EGOFETs) have been developed to measure pH and cation concentrations. Future work will aim to improve the sensitivity of these sensors by employing more advanced design techniques while maintaining rapidness, low cost, specificity, and sensitivity as important criteria.
