The highly selective and sensitive determination of pesticide residues in food is critical for human health protection. Herein, the specific selectivity molecularly imprinted polymers (MIPs) was proposed to construct an electrochemical sensor detection carbendazim (CBD), one famous broad-spectrum fungicides, by combining with synergistic effect bioelectrocatalysis nanocomposites. Gold nanoparticle-reduced graphene oxide (AuNP-rGO) composites were electrodeposited on a polished glassy carbon...
Abstract A complex biomolecular logic system based on stimulus‐responsive enzymatically imprinted polymer is constructed for the first time. Glucose oxidase (GOD) served as template to construct molecularly (MIP) with N‐isopropylacrylamide (NiPAAm) thermo‐sensitive monomer. The prepared MIP film electrodes demonstrate reversible GOD‐, temperature‐, and glucose‐sensitive on‐off electrochemiluminescence (ECL) behaviors toward luminol. Moreover, addition of ferrocenedicarboxylic acid (Fc(COOH)...
In the present work, reduced graphene oxide (rGO)/poly(N-isopropylacrylamide) (PNIPAA) composite films were electrodeposited onto surface of Au electrodes in a fast and one-step manner from an aqueous mixture (GO) dispersion N-isopropylacrylamide (NIPAA) monomer solutions. Reflection–absorption infrared (IR) Raman spectroscopies employed to characterize successful construction rGO/PNIPAA films. The exhibited reversible potential-, pH-, temperature-, sulfate-sensitive cyclic voltammetric (CV)...
In this study, we developed a novel molecularly-imprinted electrochemical sensor based on glassy carbon electrode (GCE) decorated by graphene–Prussian blue (GR–PB) composites for the selective and sensitive determination of butylated hydroxyanisole (BHA). The polymers (MIPs) were synthesized BHA pyrrole as template molecule functional monomer, respectively. Also, MIPs assembled surface GR–PB/GCE electropolymerization. was characterized cyclic voltammetry (CV), scanning electron microscopy...
A series of biomacromolecular logic gates and functional devices with cyclic voltammetric (CV) electrochemiluminescence (ECL) responses as output signals were established on the basis molecularly imprinted polymer (MIP) film electrodes. The MIP films electropolymerized surface Au electrodes o-phenylenediamine (OPD) monomer chloramphenicol (CP) template molecule. simultaneous CV ECL Ru(bpy)32+ significantly enhanced by addition natural DNA in solution at after CP removal. Ru(bpy)32+–DNA...
Abstract A logic‐gate system with three outputs and inputs was developed based on the bioelectrocatalysis of glucose by oxidase (GOx) entrapped in chitosan films electrode surface means ferrocenedicarboxylic acid (Fc(COOH) 2 ). Cyclic voltammetric (CV) signals Fc(COOH) exhibited pH‐triggered on/off behavior owing to electrostatic interactions between film probe at different pH levels. The addition greatly increased oxidation peak current ( I pa ) through electrocatalytic reaction. were...
Abstract A molecularly imprinted electrochemical sensor was fabricated based on a gold electrode modified by chitosan-multiwalled carbon nanotube composite (CS-MWCNTs) multilayer films and nanoparticles (AuNPs) for convenient sensitive determination of oxytetracycline (OTC). The CS-MWCNTs composites AuNPs were used to augment electronic transmission sensitivity. polymers (MIPs) synthesized using OTC as the template molecule o-phenylenediamine (OPD) functional monomer. They...
The polymerization of N,N'-diethylacrylamide (DEA) into PDEA hydrogels could be initiated by glucose oxidase (GOD) in the presence glucose, Fe2+ and oxygen. Based on this, semi-interpenetrating polymer network (semi-IPN) films containing PDEA, hyaluronic acid (HA) GOD were prepared electrode surface. electroactive probe ferrocenedicarboxylic (Fc(COOH)2) solution demonstrated reversible pH-, temperature- SO42−-sensitive cyclic voltammetric (CV) on-off behavior at film electrodes.
