Immunosensor calibration plot: normalized response of the immunosensors functionalized with bovine serum albumin (BSA), Tween-20, anti-NS1 antibody after incubation with NS1 protein in PB [n = 7; y = −4.88x − 35.23, R² = 0.99] (■), after incubation with PB only [n = 6, y = −0.36x − 2.4, R² = 0.91] (▼), and after incubation with BSA protein in PB [n = 9; y = −0.24x − 2.6 R² = 0.53] (▲). Normalized response of the immunosensors functionalized with BSA and Tween-20 but without antibody to the incubation of NS1 protein in PB [n = 8; y = −0.34x − 2.9, R² = 0.93] (♦). The data points are the mean of measurements from independent immunosensors, and error bars represent ±1 standard deviation.
