The use of impedance measurements to detect the presence of pathogens attached to antibody-coated beads. In a fluidic device antibodies are immobilized on a surface of a patterned interdigitated electrode. Pathogens in a sample fluid streaming past the electrode attach to the immobilized antibodies,...http://www.google.com.au/patents/US6835552?utm_source=gb-gplus-sharePatent US6835552 - Impedance measurements for detecting pathogens attached to antibodies
