Detection of Bisphenol A in aqueous medium by screen printed carbon electrodes incorporating electrochemical molecularly imprinted polymers

Advanced Electrochemical Molecularly Imprinted Polymer as Sensor Interfaces

“…The correct leaching of BaP or BPA from e-MIPs was confirmed by the absence of any major characteristic band of these targets in the e-MIP spectrum and by the high similitude of e-MIPs and e-NIPs spectra. SEM pictures revealed spherical particles with average diameters from 0.22 µm for e-MIP-VFc-DVB [4] to 4.40 µm for the e-MIP-FcMMA-EDMA [5]. Adsorptions of targets were studied in aqueous medium by batch experiments after an equilibration time of 24 h. The binding studies revealed that the higher values are obtained with introduction of 4-VP and DVB.…”

“…A decrease of current intensity with addition of BaP in the electrolytic solution is also observed with a more important impact for copolymers based on VFc-EDMA with limits of detection of 0.93 and 2.47 µM for e-MIP VFc-EDMA-CPE and e-MIP VFc-4VP-EDMA-CPE, respectively. This strategy was extended to the detection of bisphenol A (BPA) [5]. For this FcMMA was taken as functional redox tracer with 4-VP co-monomer, EDMA as crosslinker.…”

“…These new e-MIP microbeads particles were incorporated in a graphite paste to prepare screenprinted carbon electrodes. A highly sensitivity for BPA in aqueous medium was obtained with a limit of detection of 0.06 nM [5]. Here, we present a resume of our research on electrochemical Molecularly Imprinted Polymers (e-MIPs).…”

Electrochemical molecularly imprinted polymers as material for pollutant detection

“…Recently, we extended this strategy to e-MIP for bisphenol A (BPA) and integrated these new e-MIPs in screen printed electrodes. A limit of detection of 0.06 nmol/L of BPA was obtained [10,11]. This strategy has also been taken up to detect vancomycin, an antibiotic target, with electroactive MIPs prepared by solid-phase synthesis with different amounts of VFc and ferrocenylmethyl methacrylate into polymerization mixture [12].…”

Molecularly Imprinted Polymer Pearls Obtained by Phase Inversion for the Selective Recognition of Hypericin

“…By using MIT, low cost and high stability materials (known as molecularly imprinted polymers, MIPs), containing cavities able to recognize selectively templates ranging from valuable or toxic small molecules can be easily prepared. Consequently, these attributes make MIPs ideal for replacing the extensive materials commonly used in solid-phase extraction [4,5], drug delivery [6], sensors [7,8] and purification and separation [9][10][11].…”
