Table 2. Multiplexed Performance of the Electrochemical Devicea.
| biomarker | added concentration | interpolated concentration | recovery (%) |
|---|---|---|---|
| IL-8 | 600 pg/mL | 583 (67) pg/mL | 97.2 |
| TNF-α | 1000 pg/mL | 893 (199) pg/mL | 89.3 |
| MPO | 1000 ng/mL | 831 (271) ng/mL | 83.1 |
The recorded current signals at 1.6 s were used to interpolate the concentration values in the respective calibration curves. The standard deviation values of three replicates are indicated in brackets.
