  • Impedance assessment of cell suspensions in space flight

        In this paper we evaluate the viability of cell suspensions with the assessment of their bioelectric properties. A method for evaluation of cell suspensions, based on the method of pulse impedance. The frequency response of the electric impedance of suspensions chondroblasts, determined by analysis of the transition function. Under the transition function is meant to test the reaction of the object exposure, for which current is used as a reaction - voltage electrodes placed in the sample suspension. After the time-frequency transform data to a PC, the transfer function is considered in the space of states that characterize the electrical properties of multicomponent biological tissues, which allows us to go to the electrical equivalents of its constituents. The measurement process, i.e. impact on the sample cell suspension is carried out within the pulse of electric current, which allows a quick assessment of the cell suspension.
