(A) Time dependence of normalized source-drain current of the CNT-biosensor at the source-drain bias of 0.1 V and at gate bias of 0 V after the introduction of IL-6 target protein at various concentrations onto the IL-6 aptamer functionalized CNT-biosensor. Arrows indicate the points of IL-6 target protein injection; (B) The Sensitivity of IL-6 aptamer CNT-biosensor as a function of IL-6 protein concentration (1 pg to 10 ng /mL). The inner box demonstrates the data in logarithmic scale.
