In this work, a biomimetic sensor elaborated by direct electrospinning of molecular imprinted poly (ethylene co-vinyl alcohol) (EVOH) onto gold electrodes was proposed for impedimetric creatinine detection. Dimethylsulfoxyde (DMSO) was selected as polymer solvent and creatinine (1% wt) was used as template. In the optimal conditions of fabrication (20% wt EVOH, electrical voltage: 20 kV, collection distance: 30 cm), the sensor response was proportional to log [creatinine concentratio in the 1 fg.L-1-1 μg.L-1 range. We also showed that the sensor could be reused at least three times and that the response of the non imprinted polymer control sensor, prepared the same way but in absence of creatinine, was very low.
