Electrodot: method for analyzing biological samples in matrix spots fixed by the action of an electrical current combined with a pressure difference

Method and fixing device Fig3 membrane, matrix of spots, of all or part of biological samples such that each sample in the simultaneous or sequential action of an electric field Figure 1.4 and pressure as Figure 1.5 the electric field has a direction perpendicular to the fixing membrane, and a differential potential between the two faces of the fixing membrane, and such that the pressure has a pressure differential AP between the two faces of the membrane.
