The media office of the Ural Federal University states that scientists at the university have created a chemical sensor that can detect abdominal pains in their early stages in just 5-7 seconds by examining saliva.
“Scientists from the Ural Federal University have created a chemical sensor to determine the pH level in biological fluids at the molecular level. With its help, gastritis, ulcers, duodenitis and other gastrointestinal diseases can be diagnosed at their early stages, ”the office said. . In a statement.
According to the creators, a fluorophore was used in this sensor, which glows in a certain range under the influence of optical radiation. That is, it is able to detect the smallest change in the level of рН in biological fluids when exposed to radiation with a special analyzer (spectrophotometer), and the result appears only after 5-7 seconds.
“Modern fluorometric pH level sensors are based on small organic molecules. As a rule, they are very sensitive and detect the desired substance at very low concentrations, even at nanoscale concentrations. The sensor we created is based on a New compound. It is a fluorinated compound that allows us to capture the photophysical and chemosensory properties of molecules. where we put the piece.
According to the creators, this sensor does not require catalysts such as nickel, copper and palladium, so it is not toxic. It is also water -soluble and can even be used to determine the acidity level of water and to determine pathological processes in medicine.
