Fig. 3. (A) Relationship between different concentrations of target miRNA-21 (10 pM, 20 pM, 50 pM, 100 pM, 150 pM, 200 pM) and PGM signal. Inset: a linear standard curve from 10 pM to 200 pM (R2 = 0.997). (B) Response of PGM for the detection of different miRNAs by the POCT assay. The concentration of miRNAs was 200 pM. Data are means ± SD (n = 3).
