a Chronoamperometric curves obtained for the characterization of the l-lactate biosensor in a concentration range from (1) 1 × 10–7 M to (2) 1 × 10–3 M. b Calibration curve obtained from the mean value of the current density of the last 30 s for each analysed l-lactate concentration. Each point represents the mean current value of three replicates recorded consecutively with the same biosensor, with the error bars being the corresponding standard deviation.
