Figure 1: ELIME (enzyme-linked immunomagnetic electrochemical) detection of S. typhimurium cells. Bacteria samples (1 ml) were immunomagnetically captured with anti-heat-killed Salmonella antibody-coated magnetic beads, reacted with AP-conjugated anti-heat-killed Salmonella antibody, and detected electrochemically after a short reaction with AP substrate as previously described. The above plot shows the electrochemical responses (current) for irradiation-killed (open squares) and heat-killed (closed circles) S. typhimurium (bacteria). The error terms in the equations are the standard errors of the slopes and intercepts.
