Abstract: A monolithic ceramic bioreactor for manipulating biofluids at a low flow having formed therein at least one fluid passageway, at least one electromagnetic pathway defined by a high &mgr; magnetic material and an electrically conducting microcoil, a first and second electrode, and a biofluid comprising at least one chemical specie within a buffer solution for preserving the activity of an enzyme contained within a bioassay for genetic reaction. The device is characterized as generating a magnetic field and an electric field, perpendicular to the magnetic field, when under the application of a first and second current. In combination the magnetic field and the electric field characterized as generating a Lorentz force. The biofluid includes sufficient conductivity for fluid motion when under the influence of the Lorentz force generated within the monolithic structure, thereby providing for the manipulating of the biofluid through the monolithic structure.
