Blood counts are routinely carried out before operations,in cases of infection, or when testing for a variety of diseases, and such as anemia and leukemia. A key value in this test is the number of red blood cells (erythrocytes). Scientists at the University of Oxford (UK) beget now introduced a simple nano-electrochemical process for the rapid,precise determination of the erythrocyte count. As described in the journal Angewandte Chemie, the test also determines the activity of individual erythrocytes toward hydrogen peroxide.
