Korean scientists have developed a method for high-speed nanoPCR diagnostics of coronavirus, according to the journal Nature Biomedical Engineering. The authors of the study stated that with the new technology, test results can be obtained within 20 minutes through the use of hybrid nanomaterials. The main element of the technology is a magnetoplasmonic nanoparticle (MPN), consisting of a magnetic material in the core and a gold shell. According to scientists, it takes about 17 minutes to diagnose one patient's blood sample. They noted that the performance of the instrument can be increased by equipping it with a wheel for loading multiple samples at the same time. "By improving and miniaturizing the technology, we have shown that it is possible to perform PCR-based diagnostics even in the field," said study leader Cheon Jin-Woo. Earlier, therapist Olga Burlakova said that the consumption of foods that change the acid-base balance in the body increases the risk of COVID-19 infection. According to her, maintaining the acid-base balance is necessary for the normal course of biochemical reactions, the optimal functioning of enzymes and the preservation of immunity. As Burlakova clarified, the greatest danger is represented by products made from white flour (cookies, buns), cow's milk (butter, sour cream), refined sugar, as well as alcohol, strong tea and coffee.
