Amperometric response for SWCNT immunosensors incubated with MMP-3 (concentration in pg mL−1 labeled on curves) in 10 μL of undiluted newborn calf serum for 1.25 h: (A) current at −0.3 V and 2000 rpm using the Ab2–HRP polymeric beads bioconjugate. Controls shown on left with MMP-3 concentrations: full SWCNT immunosensor with 0 pg mL−1 MMP-3. (B) Influence of log MMP-3 concentration on steady state current for immunosensor using Ab2–Polybead–HRP bioconjugate. Error bars in part B represent device-to-device standard deviations (n = 3).
