Russian scientists working in the international group have developed a new design of electronic language. She uses cheap disposable sensors to analyze liquid. This innovation will find applications in medical, ecological and food, report RIA Novosti is related to the Russian Science Fund (RNF).
In liquids, drinks and food products, there are many different ingredients. To determine their ingredients, sometimes enough to understand what kind of sample belongs to. For example, in medicine, it is necessary to determine whether the patient is healthy or not, and in the food industry – to distinguish fake from the original product. To do this, use special devices called “electronic language”.
Press services of the Russian Science Fund report that modern “electronic language” are expensive devices with reusable sensors, must be carefully cleaned after each use to eliminate the ability to pollute the following sample with foreign substances. In addition, the individual electrodes in the Viking language should be different to recognize the various chemical compounds in the analyzed liquid.
To solve this problem, experts from the Institute of basic forms were named after A. Nesmeyanov, the Russian Academy of Sciences, along with scientists from the University of Barcelona (Spain), created a creative design of sensor. This design is based on disposable languages, disposable languages with electrodes are covered by a thin metal frame. These frames are compounds including different metal ions (zinc, copper, nickel and iron) and organic molecules that form a porous structure.
The peculiarity of this development is its accessibility, because the materials for it are inexpensive, and the production process is very simple. In addition, the device can only be used once, scientists said. Although the accuracy of the definition of substances is not as high as in commercial devices, this development may be especially useful in this field, where there is no way to use bulky equipment or ensure the purification of appropriate sensors, materials said.
