An Immunosensor for Pathogenic Staphylococcus aureus Based on Antibody Modified Aminophenyl-Au Electrode
(a) Nyquist plots of impedance spectra obtained for increasing concentrations of S. aureus (ATCC 25923) in PBS and Fe (A) 101 CFU per mL, (B) 102 CFU per mL, (C) 103 CFU per mL, (D) 104 CFU per mL, (E) 105 CFU per mL, (F) 106 CFU per mL, and (G) 107 CFU per mL. (b) Relative variation of () versus concentration of S. aureus (ATCC 25923) in PBS and Fe (A) incubated on antibody modified aminophenyl-Au electrode and (B) incubated on aminophenyl-Au electrode.
