Russia.. Inventing a Device to Detect Bacteria and Viruses

Scientists from the Saratov branch of the Institute of Radioelectronic Technology have created a device equipped with software for detecting and evaluating the capabilities of bacterial cells in the environment.

The information bureau of the Russian Ministry of Science indicates that this device can also assess the sensitivity of bacteria to antibiotics, as well as detect antibiotics in liquids.

“The results of our study showed that it is possible to detect bacterial cells with a sensitivity threshold of less than 103 cells per milliliter and virus cells with a sensitivity threshold of less than 104 viruses per milliliter,” says Boris Zaitsev, Ph.D. director of the institute. “Antibiotics in liquids are equivalent to 0.5-1µg per milliliter. So this device will be useful in detecting bacterial cells and viruses in the blood and lymphatic system of humans and animals. As well as in drinks and liquid foods.”

The device consists of a resonator with a tangential electric field based on a plate of non-existent lithium niobate salt 0.5 mm thick. On the one hand, there are two electrodes with dimensions of 5 and 10 mm, and on the other hand, a container for liquid. Part of the electrodes and the surrounding area are covered with an absorbent layer to capture the waves. Part of the analysis includes a digital signal generator and a microcontroller connected to a personal computer.
