Abstract
The possibility of antibacterial activity assay using an acoustic non-contact biological sensor based on two piezoelectric plates separated by an air gap was demonstrated on the example of amoxicillin and Escherichia coli for the first time. An acoustic wave with transverse horizontal polarization is excited in the bottom plate of the sensor. The upper plate serves as the bottom of the container with the studied cell suspension. It was shown that the addition of an antibiotic to the cell suspension leads to a change in the parameters of the sensor. The effect of amoxicillin on microbial cells was monitored by laser microscopy and standard microbiological culture. The possibility of express analysis of the drug’s antibacterial activity using a biological sensor based on the use of a slit acoustic wave is shown.Keywords
