Paper-Based Competitive Immunochromatography Coupled with an Enzyme-Modified Electrode to Enable the Wireless Monitoring and Electrochemical Sensing of Cotinine in Urine. SENSORS 2021; 21:s21051659. [PMID: 33670868 PMCID: PMC7957614 DOI: 10.3390/s21051659] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Revised: 02/21/2021] [Accepted: 02/23/2021] [Indexed: 12/17/2022]
Abstract
This paper proposes a combined strategy of using paper-based competitive immunochromatography and a near field communication (NFC) tag for wireless cotinine determination. The glucose oxidase labeled cotinine antibody specifically binds free cotinine in a sample, whereas the unoccupied antibody attached to BSA-cotinine at the test line on a lateral flow strip. The glucose oxidase on the strip and an assistant pad in the presence of glucose generated H2O2 and imposed the Ag oxidation on the modified electrode. This enabled monitoring of immunoreaction by either electrochemical measurement or wireless detection. Wireless sensing was realized for cotinine in the range of 100-1000 ng/mL (R2 = 0.96) in PBS medium. Undiluted urine samples from non-smokers exhibited an Ag-oxidation rate three times higher than the smoker's urine samples. For 1:8 diluted urine samples (smokers), the proposed paper-based competitive immunochromatography coupled with an enzyme-modified electrode differentiated positive and negative samples and exhibited cotinine discrimination at levels higher than 12 ng/mL. This novel sensing platform can potentially be combined with a smartphone as a reader unit.

Abstract
Non-catalytic direct electron transfer (DET) signal of Compound I of horseradish peroxidase (POD) was first detected at 0.7 V on POD/carbon nanotube mixture-modified electrodes. Excellent performance of DET-type bioelectrocatalysis was achieved with POD immobilized with glutaraldehyde on Ketjen Black (KB)-modified electrodes for H2O2 reduction with an onset potential of 0.65 V (vs. Ag | AgCl | sat. KCl) without any electrode surface modification. The POD-immobilized KB electrode was found to be suitable for detecting H2O2 with a low detection limit (0.1 μM at S/N = 3) at -0.1 V. By co-immobilizing glucose oxidase (GOD) and POD on the KB-modified electrode, a bienzyme electrode was constructed to couple the oxidase reaction of GOD with the DET-type bioelectrocatalytic reduction of H2O2 by POD. The amperometric detection of glucose was performed with a high sensitivity (0.33 ± 0.01 μA cm-2 μM-1) and a low detection limit (2 μM at S/N = 3).

Abstract
Enzymes play an essential role in various detection technologies. We show here that interstrand cross-linked oligodeoxynucleotides (CL-ODNs) can provide stable scaffolds for efficiently coupling two types of enzymatic reactions on an electrode. Glucose can be electrochemically detected using glucose oxidase (GOx) and horseradish peroxidase (HRP). When both GOx and HRP were immobilized on an electrode surface by attachment at the termini of CL-ODNs, the current value was markedly increased compared with that obtained on a standard ODN scaffold. The relative orientation of the enzymes on the electrode strongly affected the current intensities. The CL-ODN also allowed GOx-HRP to form a complex on the tiny surface of a microelectrode, resulting in the imaging of local glucose distribution. These results suggest that CL-ODNs have potential utility in other sensing technologies.

Abstract
This work describes development and optimization of a generic method for the immobilization of enzymes in chemically synthesized gold polypyrrole (Au-PPy) nanocomposite and their application in amperometric biosensors. Three enzyme systems have been used as model examples: cytochrome c, glucose oxidase and polyphenol oxidase. The synthesis and deposition of the nanocomposite was first optimized onto a glassy carbon electrode (GCE) and then, the optimum procedure was used for enzyme immobilization and subsequent fabrication of glucose and phenol biosensors. The resulting nanostructured polymer strongly adheres to the surface of the GCE electrode, has uniform distribution and is very stable. The method has proved to be an effective way for stable enzyme attachment while the presence of gold nanoparticles provides enhanced electrochemical activity; it needs very small amounts of pyrrole and enzyme and the Au-PPy matrix avoids enzyme leaking. The preparation conditions, Michaelis-Menten kinetics and analytical performance characteristics of the two biosensors are discussed. Optimization of the experimental parameters was performed with regard to pyrrole concentration, enzyme amount, pH and operating potential. These biosensors resulted in rapid, simple, and accurate measurement of glucose and phenol with high sensitivities (1.089 mA/M glucose and 497.1 mA/M phenol), low detection limits (2 x 10(-6)M glucose and 3 x 10(-8)M phenol) and fast response times (less than 10s). The biosensors showed an excellent operational stability (at least 100 assays) and reproducibility (R.S.D. of 1.36%).

Abstract
Amperometric bienzyme electrodes with horseradish peroxidase (HRP) and glucose oxidase (GOx) co-immobilized on polymethylferrocenyl dendrimers deposited onto platinum electrodes have been used for determination of the hydrogen peroxide produced by the oxidase during the enzymatic reaction. The redox dendrimers consist of flexible poly(propylenimine) dendrimer cores functionalised with octamethylferrocenyl units. The effects of dendrimer generation, the thickness of the dendrimer layer, substrate concentration, interferences, and reproducibility on the response of the sensors were investigated. The new bienzyme biosensors respond to substrate at work potential values between 200 and 50 mV (vs. SCE), have good sensitivity, and are resistant to interferences. Figure.

Abstract
Gold nanotubular electrode ensembles were prepared by using electroless deposition of the metal within the pores of polycarbonate track-etched membranes. Mono-enzyme (GOx) and monolayer/bilayer bienzyme (GOx/HRP) bioelectrodes were prepared by immobilizing the enzymes onto gold nanotubes surfaces modified with mercaptoethylamine. Batch amperometric responses to glucose for the different bioelectrodes were determined and compared. The response of the two geometries (monolayer and bilayer) of the bienzyme electrodes was shown to vary with regard to sensitivity at detection potentials above 0V. On the contrary, at detection potentials below 0V, no noticeable influence of the configuration of the bienzyme on the response intensity was observed. The mono-enzyme (650 microAmM-1 in benzoquinone (BQ) at -0.8 V versus Ag/AgCl) and the two bienzyme bioelectrodes (+/-400 microAmM-1 in hydroquinone (H2Q) at -0.2V versus Ag/AgCl) display remarkable sensitivities compared to a classical GOx-modified gold macroelectrode (13 microAmM-1 in BQ at -0.8 V versus Ag/AgCl). A remarkable feature of the bienzyme electrodes is the possibility to detect glucose at very low applied potentials where the noise level and interferences from other electro-oxidizable compounds are minimal. Another important characteristic of the monolayer bienzyme electrode is the possible existence of a direct electronic communication between HRP and the transducer surface.

Abstract
Hydrogen peroxide sensors where horseradish peroxidase (HRP) is incorporated into pyrrole/3-alkylsulfonate pyrrole copolymer films deposited on an SnO2 electrode (HRP/Py-PS electrode) were investigated with regard to the effects of the fabrication parameters (electropolymerization charge, deposition current density, and electrodeposition solution pH) on the amount of surface-immobilized enzyme and the sensor response. The amount of incorporated enzyme was determined with a method recently developed by ourselves. The results suggest that the amount of entrapped enzyme increases almost linearly with the total charge passed, and strongly depends on the polymer film growth rate and the electropolymerization pH. These findings open up a way to control the amount of enzyme and the resultant response of the biosensor by modifying the preparation conditions.

Abstract
Glucose oxidase (GOD) was immobilized in four different conducting polymer matrices, namely: polypyrrole, (PPy), poly(pyrrole-graft-polytetrahydrofuran), (1) and (3); and poly(pyrrole-graft-polystyrene/polytetrahydrofuran), (2). The kinetic parameters V(max) and K(m), and the optimum temperature were determined for both immobilized and native enzymes. The effect of electrolysis time and several supporting electrolytes, p-toluenesulfonic acid, p-toluene sulfonic acid (PTSA), sodium p-toluene sulfonate, sodium p-toluene sulfonate (NaPTS), and sodium dodecyl sulfate, sodium dodecyl sulfate (SDS), on enzyme immobilization were investigated. The high K(m) value (59.9 mM) of enzyme immobilized in PPy was decreased via immobilization in graft copolymer matrices of pyrrole. V(max), which was 2.25 mM/min for pure PPy, was found as 4.71 mM/min for compound (3).

Abstract
An enzyme immobilization method has been developed by electropolymerization chemistry of conducting polymer which results in a more effective and reproducible enzyme electrode. As a model system, in this study, glucose oxidase (GOD) was conjugated with a polyanion, poly(2-acrylamido-2-methylpropane sulfonic acid), via a poly(ethylene oxide) spacer to improve the efficiency of enzyme immobilization into a conducting polymer. GOD was successfully conjugated with a high conjugation yield of more than 90%, and its bioactivity was preserved. The resulting polyanion-GOD conjugate was used as a dopant for the electrochemical polymerization of pyrrole. Polypyrrole was effectively deposited on a Pt wire working electrode with the polyanion-GOD conjugate. The enzyme electrode responded to glucose concentrations of up to 20 mM with a sensitivity of 40 nA/mM at an applied potential of 0.4 V within a response time of 30 s. Although the response signal decreased at the low applied potential of 0.3 V, the enzyme electrode showed sensitive response signals of about 16 nA/mM up to 20 mM in glucose concentration. Under the deoxygenated condition, reduced but clear response current signal was obtained. The results show that the current signal response of the enzyme electrode to glucose concentration may be produced by mixed mechanisms.
