Amperometric response for AuNP immunosensor incubated with IL-8 (concentration in fgmL−1 labeled on curves) in undiluted calf serum (10 μL) for 1.25 h. A) Current at −0.3 V and 2000 rpm using Ab2–MB–HRP bioconjugate. Control shown on left with AuNP immunosensor with 0 pgmL−1 IL-8. B) Corresponding calibration curve of IL-8 immunosensor using Ab2–MB–HRP bioconjugate. Errors bars represent device-to-device standard deviations. y = 7.73 + 5.78log(x), R = 0.93199.
