OECT biosensor for lactate detection. Ig (a) and Id (b) vs. time curves obtained for the OECT sensor with Ag/Ach = 4, after the addition of increasing lactate amounts (Vgs = +0.8 V; Vds = +0.1 V) in 0.1 M PBS (pH = 7.00). The additions are indicated with an arrow. Plot of Ig (c) and Id (d) as a function of lactate concentration.
