[Prospects for application of aptamers in diagnostics of bacterial infections]

Nucleic acid-based aptamers are widely accepted as promising tools for development of a plethora of diagnostic and therapeutic preparations, as well as means ofenvironmental monitoring. Aptamers can be regarded as fully synthetic analogs of antibodies. At the same time, certain properties ofaptamers render them superior to antibodies in terms of development of new diagnostic and monitoring systems that combine high sensitivity and specificity with high reproducibility and inexpensive manufacturing. In particular, the aptamers tailored to bind biomolecules and live cells can be employed in solving the problem of combining short analysis time with high sensitivity and specificity in detection of pathogenic bacteria. The present review summarizes the current state of the techniques developed for aptamer-based detection of bacteria and their components and discusses the potential of their practical application.
