Abstract
⺠Magnetic bead conjugated bacteria cells were concentrated by external magnetic field. ⺠Concentrated bacteria cells were captured by antibody immobilized nanoporous membrane immunosensor. ⺠A linear relationship between bacteria concentration and impedance signal was found in the range from 100 to 104 CFU/mL. ⺠The detection limit of 10 CFU/mL was achieved for E coli O157:H7 detection.
