“…Previously, when studying the possibility of detecting kanamycin in a liquid, a sensor based on a resonator with a lateral electric field was connected to the precision LCR meter 4285a (Agilent, Santa Clara, CA, USA) [39]. This meter has a high accuracy (up to 0.1%), but is very expensive and bulky and allows measuring biological objects only in laboratory conditions.…”

“…Therefore, a special device was developed, which has a somewhat lower accuracy, but is distinguished by the ease of manufacture, portability, and low cost. Previously, we have shown the possibility of analyzing antibiotics directly in a liquid using a sensor based on a resonator with a lateral exciting electric field [39]. Although the sensor itself is small (60 × 40 × 20 mm 3 ), the precision LCR meter 4285A (Agilent, Santa Clara, CA, USA) was used to measure the sensor parameters.…”

In this study, a compact acoustic analyzer for express analysis of antibiotics based on a piezoelectric resonator with a lateral electric field and combined with a computer was developed. The possibility of determining chloramphenicol in aqueous solutions in the concentration range of 0.5–15 μg/mL was shown. Bacterial cells that are sensitive to this antibiotic were used as a sensory element. The change in the electrical impedance modulus of the resonator upon addition of the antibiotic to the cell suspension served as an analytical signal. The analysis time did not exceed 4 min. The correlation of the experimental results of an acoustic sensor with the results obtained using the light phase-contrast microscopy and standard microbiological analysis was established. The compact biological analyzer demonstrated stability, reproducibility, and repeatability of results.

“…Sometimes, there is a need to determine the mechanical properties of liquids as well as mixtures based on liquid and solid particles with high accuracy [ 7 ]. A similar need arises when monitoring the state of various reservoirs, wastewater, and groundwater, as well as in areas of science such as biology, medicine, food, pharmaceutical and in the gas- and oil-producing industry [ 8 , 9 , 10 , 11 ]. In this case, the choice of sensors is determined by factors such as the reliability, accuracy, commercial availability, and ease of use [ 12 , 13 , 14 , 15 ].…”

This study examines the effect of suspensions based on pure glycerol and diamond powder with different concentrations on the characteristics of resonators with a longitudinal electric field. We used two disk resonators made of the quartz and langasite plates with round electrodes on both sides of the plate and resonant frequencies of 4.4 and 4.1 MHz, operating in shear and longitudinal acoustic modes, respectively. Each resonator was mounted on the bottom of a 30 mL liquid container. During the experiments, the container was filled with the suspension under study in such a way that the resonator was completely immersed in the suspension, and the frequency dependences of the real and imaginary parts of the electrical impedance of the resonator were measured. As a result, the shear modulus of the elasticity and shear coefficient of the viscosity of the studied suspensions were determined. The material constants of the suspensions were found by fitting the theoretical frequency dependences of the real and imaginary parts of the electrical impedance of the resonator to the experimentally measured ones, which was calculated using Mason’s equivalent circuit. As a result, the dependencies of the density, shear modulus of elasticity, shear viscosity coefficient, and velocity of the shear acoustic wave on the volume concentration of the diamond particles were constructed.

“…До недавнего времени акустические датчики не применялись для определения антибиотиков и первое упоминание о возможности их применения для оценки воздействия антибактериальных препаратов на бактерии приведено в работе [2]. Перспективность применения датчика на основе резонатора с поперечным электрическим полем с помощью микробных клеток для определения антибиотиков непосредственно в жидкости показана на примере канамицина [3] и полимиксина [4]. https://doi.org/10.20914/2304-4691-2023-1-8-9…”
