Design of a polypyrrole MIP-SAW sensor for selective detection of flumequine in aqueous media. Correlation between experimental results and DFT calculations

Abstract

A shear horizontal surface acoustic wave sensor (SH-SAW) operating at 104 MHz was functionalized with a polypyrrole (PPy) molecularly imprinted polymer (MIP) for selective detection of flumequine (FLU) in aqueous media.

Highly Selective Polypyrrole MIP-Based Gravimetric and Electrochemical Sensors for Picomolar Detection of Glyphosate

“…As demonstrated in our previous studies [ 21 , 22 ], electrodepositing a thin polypyrrole blocking layer (BL) on a gold electrode is necessary to prevent the formation of complexes with gold. This primer layer has also the advantage to lower the oxidation potential of pyrrole during the preparation of the MIP [ 22 ].…”

“…An interesting alternative approach consists of the design of sensors functionalized with molecularly-imprinted polymer (MIP) for the selective detection of glyphosate. The rationale of this strategy is related to the fact that molecular imprinting is low-cost, sensitive, selective, specific, and versatile [ 21 , 22 , 23 , 24 ].…”

Thin Melamine Imprinted Sol Gel Coating on Silica Beads: Experimental and Statistical Physics Study

“…The thin coatings developed at the surface have allowed good mass transfer and rapid uptake of target molecule. Similarly, we have prepared ultrathin molecular imprinted membranes in the development of sensors for the detection of melamine in milk [14], or flumequine antibiotic in seawater [15]. The resulting MIP composites acted as receipt material with highly accessible binding sites with faster mass transfer compared to those prepared by conventional bulk polymerization technique.…”

Picomolar Detection of Heavy Ions with Surface Acoustic Wave Sensors Functionalized with New Synthetized Anthracene Derivates

“…In this study, we have chosen to functionalize surface acoustic wave (SAW) sensors with three new anthracene derivatives BP-AN, TDP-AN and BPS-AN. Several reasons have motivated this choice: -a relatively simple synthesis of these three molecules, -the possibility of several reuse of the same transducer, as all the investigated molecules are soluble in common organic solvents, -the rarity of anthracene derivates' use for heavy ions detection -and the sensitivity and accuracy of SAW sensors [4,5]. Gravimetric measurements, supported by quantum chemical calculations, based on the density functional theory, were considered to investigate the affinity of the different anthracene molecules towards Hg 2+ and Cu 2+ ions.…”
