Abstract
Mixing of a sample containing a suspect bioagent or antigen with 1° recognition molecule coated magnetic beads in the preliminary stage of an enzyme linked immunoassay ('ELISA') procedure is emulated by first inserting the coated magnetic beads into a non-magnetic confinement region, generating a magnetic field B along the axis of said non-magnetic confinement region to agglomerate the coated magnetic beads into a porous mass; then percolating or otherwise forcing the sample solution through said porous mass; and withdrawing the magnetic field to de-agglomerate said coated magnetic beads. In seeping or otherwise flowing through the magnetic beads the molecules of the sample link to respective magnetic beads that are coated with recognition molecules.
