.Similarly,
interassay precision was estimated by recording the response of
four separately prepared sensors toward the analysis of 0.1 ng/mL
atrazine. In this case, the variation in the sensors' response was
limited to 4%. The stability of the sensor's EIS response as a
function of storage time was also evaluated. It was observed that
the proposed sensor could retain its EIS characteristics even after
40 days of storage (in 10mM PBS, pH 7.4, T = 4 C).
