Electrochemical Sensor based on Imprinted Sol-Gel Polymer on Au NPs-MWCNTs-CS Modified Electrode for the Determination of Acrylamide

Abstract: A sensitive molecularly imprinted electrochemical sensor was successfully constructed for the detection of acrylamide (AM). It is based on a glassy carbon electrode modified with a composites prepared from gold nanoparticles, multiwalled carbon nanotubes, and chitosan along with a sol-gel-based molecularly imprinted polymer (MIP) film. The latter was prepared using AM as the template molecule, 3-aminopropyltrimethoxysilane as the functional monomer, and tetraethoxysilane as the cross-linker. The MIP sensor sho… Show more

“…The synthesis procedure was compared with that reported in terms of precursors and synthesis conditions [15,[30][31][32][33][34]. As can be seen from Table S1, in all the reported synthesis routes, chemical precursors and organic solvents are used which are hazardous and expensive.…”

“…have unique conductive and good mechanical properties, such as unique nanometer size, high surface area, high electron transfer rate, high stability and the ability to be modified on the surface that can maintain the stability and activity of biorecognition molecules [107,108]. Liu et al have combined the composite of AuNPs-multi-walled carbon nanotubes (MWCNTs )-chitosan (AuNPs-MWCNTs-CS) with sol-gel MIT to construct a molecularly-imprinted electrochemical sensor for AA detection [109]. The composite of AuNPs and MWCNTs was introduced to improve the polymer conductivity and expand the surface area of electrode.…”

“…However, all the mentioned techniques are expensive, time-consuming, and they require a qualified operator and a sample preparation. On the other hand, electrochemical sensors show great potential due to their low cost, small size, fast response, portability, good sensibility, selectivity, low detection limit and are user-friendly [3,4]. Up to date, electrochemical AA sensors are based on molecular imprinting of nonconductive polymer which limits their performance because of probe molecules that have to be used.…”

“…Molecularly imprinted polymers (MIP) are synthetic polymers with specific recognition sites for targeted molecule based on a monomer, template and a cross-linker. Several nonconductive functional monomers [3][4][5][6]) were already used for the creation of MIP for AA molecule. Two of them [5,6] were used just for adsorption of AA for its indirect determination with HPLC.…”
