The bacterial surface is a complex combination of various immunogenic components of genus, species, and
strain specificity. Polyclonal and monoclonal antibodies, used widely in the manufacture of diagnostic test systems, have
traditionally served as biological components for the specific detection of bacterial cells. In molecular biology, bacterial
cell detection is performed with the help of genetic engineering technologies for cloning recognizing fragments
(hypervariable immunoglobulin domains (miniantibodies). These technologies are cheaper and can be competitive in
selectivity with hybridoma technologies. At present, research is actively working to improve cell detection sensitivity with
the use of electro-optical and electro-acoustical analysis, the main problem being to select antibodies with greater
analytical sensitivity. This review highlights the use of specific antibodies and miniantibodies in electro-optical and
electro-acoustical analysis for the detection of bacterial cells.
Keywords: Detection, antibodies, miniantibodies, electro-optical and electro-acoustic analysis, piezoelectric lateral and
longitudinal electric-field excited resonators.
