Abstract: Methods and apparatus for detecting immunochemical reactions and levels of antigens and antibodies in serum. A selected immunochemical reactant is bound to the surface of a first electrode. A second electrode is provided such that the electrodes generate a galvanic current when electrically interconnected and immersed in conductive aqueous solution. The electrodes are electrically interconnected and immersed into a conductive aqueous solution containing the complementary immunochemical reactant to the bound immunochemical reactant. The galvanic current generated by the immersed electrodes is measured as a function of time. The level of the complementary immunochemical reactant in the solution is calculated by comparing the measured current with a standard current.

Abstract: Colloidal-sized paramagnetic particles are formed with affinity ligands directly adsorbed to their surface. The colloidal-sized particles can form a colloidal disperse phase which is distributed through an aqueous dispersion medium to form a biological magnetic fluid. The fluid can be used to selectively separate cells from a cell mixture.
