Russian scientists are creating sensors that will help diagnose diseases by human breath. These sensors are very sensitive and can detect even the slightest changes in the composition of exhaled air. This was reported by Pavel Krasnov, a leading researcher at the Siberian Federal University and a project participant.
The task is to obtain sensors that are capable of determining various gases with high accuracy. Our idea is as follows: people suffering from certain diseases have a different composition of exhaled air. Based on the analysis of exhaled air, in particular, it is possible to determine pulmonary and cardiovascular diseases, and diabetes.
The difficulty lies in the fact that the concentration of these gases in the air exhaled by a person is low. Highly sensitive sensors are required to detect them.
According to Krasnov, in collaboration with employees of the Institute of Inorganic Chemistry of the Siberian Branch of the Russian Academy of Sciences in Novosibirsk, they are creating sensors. These sensors can be used in various fields, including environmental monitoring and detection of hazardous gas leaks at industrial enterprises.
The developed sensors, Krasnov emphasized, can be used repeatedly. This is a great advantage, because most other chemical sensors are either disposable or require heating to high temperatures for recovery.
But here, according to the measurements of my colleagues, the properties of the materials being developed do not change for six months, at least in the laboratory.
Earlier, scientists from the Vector Virology Center and the Research Institute of Organic Chemistry of the Siberian Branch of the Russian Academy of Sciences created a compound that effectively suppresses SARS-CoV-2 coronavirus strains. They were able to reduce the toxicity of this substance, which is characteristic of its natural form, which significantly improved its therapeutic properties.
