[Estimation of surface potential of lymphocytes from patients with leukemia using Kelvin probe mode].

The feasibilities of the Kelvin probe mode were shown to estimate a surface potential of lymphocytes from the patients with leukemia. Having compared the values of the surface potential obtained by the traditional method of microelectrophoresis and by the Kelvin probe mode, it was established that the use of the atomic force microscope made it possible to obtain data which were of specified diagnostic importance while studying lymphocyte functional status at different stages in leucopoiesis and indicated progression of the pathological process.
