This invention can help in the research of biochemical processes.
Scientists have developed a microchip that will allow you to control the saturation of tissues with oxygen. It has been tested on samples of artificial blood and on rodents that were awake and in hibernation.
Experts believe that such an invention can help in the research of biochemical processes in which it is important part of oxygen. The microchip can transmit information about the necessary amount of oxygen and the quantity that is supplied, such data will help to determine the pathological and physiological processes in the body.
Previously in such cases used non-invasive pulse oximetry, however, the accuracy of this determination was limited depending on the tissue. Hao Zhang and his colleagues have created a microchip that weighs about 80 milligrams, and its size is about one square centimeter. It is implanted in the tissue and may locally determine the level of oxygen.
The read data is transferred directly to the PC. It should be noted that previously, scientists from Denmark have created a ink for 3D printer composed of nanoparticles. Biocompatible ink will be able to identify and distribute oxygen to the printed tissues.
