| Fig. 4. Sensitivity and specificity of ATP/AAO and ATP/MOF/AAO detections for Sr2+. (a) I-V curves before and after APT/MOF/AAO responses to 100 nmol·L-1 Sr2+. After exposure to Sr2+, the APT/MOF/AAO exhibited an increase in ionic current. (b) The relationship plots between the increase in ionic current and the logarithm of Sr2+ concentration (0.01, 0.1, 1, 10, 100, and 1000 nmol·L-1) for APT/AAO and APT/MOF/AAO. (c, d) Specificity plots of nanochannels with APT/AAO and APT/MOF/AAO for Sr2+ as well as three analogues, including K+, Ca2+, and Ba2+. APT/MOF/AAO demonstrates greatly improve the detection sensitivity and specificity of Sr2+. |
