From: Portable biosensor for monitoring cortisol in low-volume perspired human sweat
(a) (Red) Portable and (Blue) Lab potentiostat comparison for the cortisol calibration dose response showing percent change in |Z| with respect to the post-antibody baseline measurement for: 0, 1, 10, 100, and 500 ng/mL of cortisol in human sweat (n = 3). Error bars are standard error of mean. (b) Portable and Lab Potentiostat impedance measurement correlation for all raw measurements represented in continuous and calibration dose response data set. (c) (Red) Portable and (Blue) Lab Potentiostat comparison of |Z| response for the 3 hour continuous detection of cortisol in human sweat with dose ranges: 0.5, 5.0, 50.0, 500.0 ng/mL. (d) Block diagram of the portable potentiostat circuit implementation. (e) Circuit drawing of the portable potentiostat.
