Abstract

The reproducibility of biosensors is an important parameter for mass-production of biosensors in different applications. In this paper, the novel strategy for screening the electrodes has been introduced to improve the reliability and performance of fabricated molecularly imprinted polymer biosensors that is the main challenge of the almost research in this field. In this strategy, we just use the non-interfering quality controls during the fabrication procedures. By using electro-fabrication approach for each step of preparation and analyzing their results, we could make the perfect decision about screening of electrodes. According to this strategy, we could prepare reproducible biosensors for detection of grail fibrillary acidic protein (GFAP). As the bare screen-printed electrodes suffer from a lack of reproducibility because of variable resistance, capacitance or electroactive area, the percent of preparing the repetitive and good performance GFAP biosensors to bare electrodes is about 36 % (13 of 36). The impedance electrochemical results showed the efficient performance of this novel approach for preparing high quality MIP biosensors.
