Electrochemical voltammetric features in living tissues of mice

The electrochemical voltammetric responses of living liver, spleen, kidney, heart, brain, skin, and S180 tumor tissues of C5710 mice were studied by u sing a complex three-electrode system. A clamp graphite electrode was used as the work electrode, a platinum wire as the counter electrode, and an Ag- AgCl wire as the reference electrode. Living tissues of mice showed disting uishable volammetric features depending on tissue types and state of health of mice. This study showed that the voltammetric features of living tissue s may be used as a possible index to discriminate the types or the malignan t states of tissues; such an index may also indicate the tumor growth stage s and the related immune response.
