Figure 2. (A) Cyclic voltammograms for EMRS in the absence (---)and presence of 10 pM (-.-.) and 10 nM miR-21(—).

Figure 2

Scan rate: 100 mV/s. (B) Amperometric curves (i-t) for EMRS tested with a series of miR-21 concentrations. From top to bottom: 0, 1 pM, 10 pM, 100 pM, 1 nM, 10 nM. Insert shows the low concentration range of the i-t curves for 10 fM and100 fM miR-21. The potential was held at 100 mV.
