    ABSTRACT: Aptasensors modified by antimony tin oxide nanoparticles-chitosan(nano ATO-CS) based on the interdigitated array microelectrodes (IDAMs) were developed for the detection of tetracycline. The nano ATO-CS film was fabricated onto the microelectrode surface, and then tetrecycline aptamer was modified onto the film to prepare an aptasensor. The results showed that the chitosan can disperse nano ATOs evenly and make them fixed on the microelectrode surface firmly. Nano-ATOs being incorporated into chitosan film can effectively promote electron transfer reaction and enhenced the electrochemical response.. The electrochemical properties of the fabricated processes were characterized by electrochemical impedance spectroscopy (EIS). Parameters affecting the aptasensor response such as pH of the base solution, the concentration of the aptamer and incubation time were optimized. Under optimum conditions, different concentration of tetracyclines was detected with the aptasensor. Based on the contributions of nano ATO-CS solutions, the proposed aptasensor displayed high sensitivity, high specificity, a low detection limit(3.0×10-9 g/mL). It could be successfully applied to the detection of tetracyclines in real milk spiked samples.

    ABSTRACT: In this paper, we developed a portable pesticides residues detection instrument by integrating an amperometric acetylcholinesterase (AChE) biosensor and a signal detecting circuit. The AChE biosensor was modified with tin oxide (SnO2) nanoparticles, chitosan, and multiwalled carbon nanotubes nanocomposite. Because the signal generated from the acetylcholinesterase biosensor is very weak, an analog signal detect circuit is elaborately designed to reduce lots of the noises and system drifts. This instrument could realize rapid detection of pesticides residues in fruits and vegetables on-site with automatic data processing, display, and data storage. The detection limit was 100 ng/L. The measurement time from sample treatment to detection was 15 min. Compared with traditional analytical methods, this proposed pesticides residues detection instrument possessed a good precision and high stability. This will be a new promising rapid detection instrument for pesticides residues in agricultural products.

    ABSTRACT: A sensitive electrochemical immunosensor based on NiAl-layered double hydroxide/graphene nanocomposites (NiAl-LDH/G) and hollow gold nanospheres (HGNs) was proposed for chlorpyrifos detection. The NiAl-LDH/G was prepared using a conventional coprecipitation process and reduction of the supporting graphene oxide. Subsequently, the nanocomposites were dispersed with chitosan (CS). The NiAl-LDH/G possessed good electrochemical behavior and high binding affinity to the electrode. The high surface areas of HGNs and the vast aminos and hydroxyls of CS provided a platform for the covalently crosslinking of antibody. Under optimal conditions, the immunosensor exhibited a wide linear range from 5 to 150 μg/mL and from 150 to 2 μg/mL, with a detection limit of 0.052 ng/mL. The detection results showed good agreement with standard gas chromatography method. The constructed immunosensor exhibited good reproducibility, high specificity, acceptable stability and regeneration performance, which provided a new promising tool for chlorpyrifos detection in real samples.

    ABSTRACT: In this paper, an aptasensor was developed based on the multiwalled carbon nanotubes-chitosan (MWCNTs-CS) and CS-prussian blue-graphene (CS-PB-GR) nanoparticles. MWCNTs-CS combined with CS-PB-GR showed good performance in the aspect of increasing the sensitivity and stability of the electrode. The tetracycline (TET) specific 5'-amine-labeled single-stranded DNA probe (anti-TET) was immobilized on the {CS-PB-GR}2/MWCNTs-CS/glass carbon electrode (GCE) via glutaraldehyde by covalent. The remarkable electrical conductivity of PB-GR and the good biocompatibility of CS enhanced the anti-TET immobilization and facilitate electron transfer between anti-TET and electrode surface. The stepwise assembly process of the aptasensor was characterized by cyclic voltammetry and scanning electron microscope. Under the optimum operating conditions, the response of differential pulse voltammetry was used for detecting the concentrations of TET. The proposed aptasensor showed detection range from 1 × 10-10 to 1 × 10-3 M and limit of detection 0.56 × 10-11 M. Furthermore, the anti-TET/ glutaraldehyde/{CS-PB-GR}2/MWCNTs-CS/GCE aptasensor was able to detect TET in milk and recoveries were satisfactory, which indicated that it could be used as a prescanning method in TET determination for the analysis of livestock products.

    ABSTRACT: A sensitive amperometric acetylcholinesterase (AChE) biosensor was developed based on the nanocomposite of multi-walled carbon nanotubes (MWCNTs), tin oxide (SnO2) nanoparticles and chitosan (CHIT). Acetylcholinesterase (AChE) and Nafion were immobilized onto the nanocomposite film to prepare AChE biosensor for pesticide residues detection. The morphologies and electrochemistry properties of the surface modification were investigated using cyclic voltammetry, differential pulse voltammetry, and scanning electron microscopy, respectively. Compared with individual MWCNTs-CHIT, SnO2-CHIT and bare gold electrode, this nanocomposite showed the most obvious electrochemical signal in the presence of [Fe(CN)6](3-/4-) as a redox couple. Incorporating MWCNTs and SnO2 into 0.2 % CHIT solution can promote electron transfer, enhance the electrochemical response, and improve the microarchitecture of the electrode surface. All variables involved in the preparation process and analytical performance of the biosensor were optimized. Under optimized conditions, the AChE biosensor exhibited a wide linear range from 0.05 to 1.0 × 10(5 )μg/L and with a detection limit for chlorpyrifos was 0.05 μg/L. Based on the inhibition of pesticides on the AChE activity, using chlorpyrifos as model pesticide, the proposed biosensor exhibited a wide range, low detection limit, good reproducibility, and high stability. Using cabbages, lettuces, leeks, and pakchois as model samples, acceptable recovery of 98.7-105.2 % was obtained. The proposed method was proven to be a feasible quantitative method for chlorpyrifos analysis, which may open a new door ultrasensitive detection of chlorpyrifos residues in vegetables and fruits.

    ABSTRACT: An electrochemical immunosensor based on interdigitated array microelectrodes (IDAMs) was developed for sensitive, specific and rapid detection of chlorpyrifos. Anti-chlorpyrifos monoclonal antibodies were orientedly immobilized onto the gold microelectrode surface through protein A. Chlorpyrifos were then captured by the immobilized antibody, resulting in an impedance change in the IDAMs surface. Electrochemical impedance spectroscopy was used in conjunction with the fabricated sensor to detect chlorpyrifos. Under optimum conditions, the impedance value change of chlorpyrifos was proportional to its concentrations in the range of 10(0)-10(5) ng/mL. The detection limit was found to be 0.014 ng/mL for chlorpyrifos. The proposed chlorpyrifos immunosensor could be used as a screening method in pesticide determination for the analysis of environmental, agricultural and pharmaceutical samples due to its rapidity, sensitivity and low cost.

    ABSTRACT: An electrochemical aptasensor modified with thionine (TH), graphene–polyaniline composite film (Gr–PANI), and gold nanoparticles (GNPs) was fabricated for convenient and sensitive determination of kanamycin. Gr–PANI nanocomposite can enhance electron transfer between work electrode surface and potassium ferricyanide. TH has excellent electrocatalytic activity toward the redox of small molecular compounds. GNPs acted as the transducer between the aptamer and Gr–PANI composites. Based on the above-mentioned advantage of these three nanaomatrials, we took advantage of their synergistic effects to fabricate a simple and sensitive aptasensor for kanamycin detection in real milk samples. The aptasensor was characterized by cyclic voltammetry, scanning electron microscope, and electrochemical differential pulse voltammetry. The experimental conditions such as concentration of aptamer, incubation temperature, time, and pH were optimized. Based on the above optimum conditions, this aptasensor showed a favorable analytical performance for kanamycin detection with a detection limit of 8.6 × 10−9 M.

    ABSTRACT: In this paper, a novel and sensitive electrochemical aptasensor for detecting tetracycline (TET) with prussian blue (PB) as the label-free signal was fabricated. A PB-chitosan-glutaraldehyde (PB-CS-GA) system acting as the signal indicator was developed to improve the sensitivity of the electrochemical aptasensor. Firstly, the PB-CS-GA was fixed onto the glass carbon electrode surface. Then, colloidal gold nanoparticles (AuNPs) were droped onto the electrode to immobilize the anti-TET aptamer for preparation of the aptasensor. The stepwise assembly process of the aptasensor was characterized by cyclic voltammetry (C-V) and scanning electron microscope (SEM). The target TET captured onto the electrode induced the current response of the electrode due to the non-conducting biomoleculars. Under the optimum operating conditions, the response of differential pulse voltammetry (DPV) was used for detecting the concentration of TET. The proposed aptasensor showed a high sensitivity and a wide linear range of 10−9 ∼ 10−5 M and 10−5 ∼ 10−2 M with the correlation coefficients of 0.994 and 0.992, respectively. The detection limit was 3.2×10−10 M (RSD 4.12%). Due to its rapidity, sensitivity and low cost, the proposed aptasensor could be used as a pre-scanning method in TET determination for the analysis of livestock products.

    ABSTRACT: In this study, a sensitive, label-free amperometric immunosensor based on graphene sheets-methylene blue nanocomposite and gold nanoparticles (GS-MB/GNPs) for the direct determination of chlorpyrifos residues was exploited. To fabricate the immunosensor, GS was first dispersed with chitosan(CS) to obtain a homogeneous solution and then mixed with MB in a ratio of 2:1. The nanocomposite film of GS-MB was dropped on the surface of glassy carbon electrode (GCE) which was first modified by the electrodeposition of GNPs. The stepwise assembly process of electroactive species on electrode surface and the performance of the immunosensor was characterized by means of cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and scanning electron microscopy (SEM), respectively. The GS-MB nanocomposite possesses good electrochemical behavior and high binding affinity to the electrode. Furthermore, high surface areas of GS and vast aminos and hydroxyls of CS provide a platform for the crosslinking of antibody. Under optimal conditions, the proposed immunosensor showed a wide linear range from 1 to 500 ng/mL with a detection limit of 0.056ng/mL. The constructed immunosensor exhibited good reproducibility, high specificity, acceptable stability and regeneration performance, which provided a new promising tool for the detection of chlorpyrifos in real samples.

    ABSTRACT: An electrochemical aptasensor was developed for the detection of kanamycin based on the synergistic contributions of chitosan-gold nanoparticles (CS-AuNPs), graphene-gold nanoparticles (GR-AuNPs) and multi-walled carbon nanotubes-cobalt phthalocyanine (MWCNTs-CoPc) nanocomposites. The aptasensor was prepared by sequentially dripping CS-AuNPs, GR-AuNPs and MWCNTs-CoPc nanocomposites onto a gold electrode (GE) surface. During the above process, these nanomaterials showed a remarkable synergistic effect towards the aptasensor.

The electrochemical properties of the modified processes were characterized by cyclic voltammetry (CV). The morphologies of the nanocomposites were characterized by scanning electron microscopy (SEM). The experimental conditions such as the concentration of the aptamer, the time, temperature and the pH were optimized. Based on the synergistic contributions of CS-AuNPs, GR-AuNPs and MWCNTs-CoPc nanocomposites, the proposed aptasensor displayed high sensitivity, high specificity, a low detection limit (5.8 × 10(-9) M) (S/N = 3) and excellent stability.

    ABSTRACT: A novel multilayer film based on Au nanoparticles (AuNPs) and polyaniline/carboxylated multiwall carbon nanotubes-chitosan nanocomposite (PANI/MWCNTs/CS) was exploited to fabricate a highly sensitive immunosensor for detecting chlorpyrifos. PANI-coated MWCNTs were prepared by in situ chemical polymerization and carboxylated MWCNTs played an important role in obtaining the thin and uniform coating of PANI resulting in the improved immunosensor response. AuNPs were used as a linker to immobilize chlorpyrifos antibody. The performance of the immunosensor was characterized by means of cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and scanning electron microscopy (SEM), respectively. All variables involved in the preparation process and analytical performance of the immunosensor were optimized. Under optimal conditions (antibody concentration: 5 μg/ml, working buffer pH: 6.5, incubation time: 40 min, incubation temperature: 25°C), the immunosensor exhibited a wide linear range from 0.1 to 40×10−6 mg/ml and from 40×10−6 mg/ml to 500×10−6 mg/ml, and with a detection limit of 0.06×10−6 mg/ml, which provided a valuable tool for the chlorpyrifos detection in real samples.

    ABSTRACT: In this reported work, an acetylcholinesterase (AChE) biosensor based on chitosan-Prussian blue-multiwall carbon nanotubes-hollow gold nanospheres (Chit-PB-MWNTs-HGNs) film was used for detecting pesticide residues in vegetable samples. Three different kinds of sample extraction methods were investigated, such as the oscillation extraction method, the ultrasonication and the centrifugation extraction method and the ultrasonication and filtration extraction method. By comparison, the ultrasonication and centrifugation extraction method was the most appropriate and efficient for the AChE biosensor. After treatment by ultrasonication and centrifugation extraction, the recoveries of the pesticides from vegetable samples were from 76.8 to 105.9% with relative standard deviation lower than 12.68%. Subsequently, the detection results with the AChE biosensor were compared with the standard gas chromatography method. The results indicated that the proposed sample pretreatment method was applicable to the AChE biosensor for pesticide residues detection in real vegetable samples.

    ABSTRACT: In this paper, an amperometric immunosensor for the detection of carbofuran was developed. Firstly, multiwall carbon nanotubes (MWCNTs) and graphene sheets-ethyleneimine polymer-Au (GS-PEI-Au) nanocomposites were modified onto the surface of a glass carbon electrode (GCE) via self-assembly. The nanocomposites can increase the surface area of the GCE to capture a large amount of antibody, as well as produce a synergistic effect in the electrochemical performance. Then the modified electrode was coated with gold nanoparticles-antibody conjugate (AuNPs-Ab) and blocked with BSA. The monoclonal antibody against carbofuran was covalently immobilized on the AuNPs with glutathione as a spacer arm. The morphologies of the GS-PEI-Au nanocomposites and the fabrication process of the immunosensor were characterized by X-ray diffraction (XRD), ultraviolet and visible absorption spectroscopy (UV-vis) and scanning electron microscopy (SEM), respectively. Under optimal conditions, the immunosensor showed a wide linear range, from 0.5 to 500 ng/mL, with a detection limit of 0.03 ng/mL (S/N = 3). The as-constructed immunosensor exhibited notable performance features such as high specificity, good reproducibility, acceptable stability and regeneration performance. The results are mainly due to the excellent properties of MWCNTs, GS-PEI-Au nanocomposites and the covalent immobilization of Ab with free hapten binding sites for further immunoreaction. It provides a new avenue for amperometric immunosensor fabrication.

    ABSTRACT: The nanocomposite comprised of O-carboxymethyl chitosan (CMCS) and gold nanoparticles (AuNPs) is successfully prepared by in-situ synthesis method. The synthesized nanocomposite has been characterized by scanning electron microscopy images. The CMCS-AuNPs nanocomposite is first modified onto the glassy carbon electrode (GCE), then the surface carboxyl group is activated by N-hydroxysuccinimide and 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride. Finally, the acetylcholinesterase (AChE) is immobilized onto the GCE to construct a novel AChE biosensor for the detection of pesticides. Because the nanocomposite was able to inherit the properties of the AuNPs and CMCS, the resulting surface provided a favorable microenvironment for AChE biosensor fabrication and maintained the bioactivity of AChE for screening of pesticide exposure. Based on the inhibition of pesticides on AChE activity using chlorpyrifos as the model compound, the results showed that the inhibition of chlorpyrifos is proportional to its concentration ranging from 0.1 to 20 μg/L and 20 to 100 μg/L, with a detection limit of 0.07 μg/L (S/N=3). The developed biosensor exhibited good reproducibility, acceptable stability, fast response, and low detection limit, thus providing a new promising tool for the rapid detection of pesticides.

    ABSTRACT: In this work, a novel amperometric immunosensor based on multi-walled carbon nanotubes-thionine-chitosan (MWCNTs-THI-CHIT) nanocomposite film as electrode modified material was developed for the detection of chlorpyrifos residues. The nanocomposite film was dropped onto a glassy carbon electrode (GCE), and then the anti-chlorpyrifos monoclonal antibody was covalently immobilized onto the surface of MWCNTs-THI-CHIT/GCE using the crosslinking agent glutaraldehyde (GA). The modification procedure was characterized by using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Under the optimized conditions, a linear relationship between the relative change in peak current of different pulse voltammetry (DPV) and the logarithm of chlorpyrifos solution concentration was obtained in the range from 0.1 to 1.0 × 105 ng/mL with a detection limit of 0.046 ng/mL. The proposed chlorpyrifos immunosensor exhibited high reproducibility, stability, and good selectivity and regeneration, making it a potential alternative tool for ultrasensitive detection of chlorpyrifos residues in vegetables and fruits.

    ABSTRACT: In this paper, a novel label-free amperometric immunosensor for the detection of carbofuran residues was developed. The deposited gold nanocrystals (DpAu)/4,4′-thiobisbenzenethiol (DMDPSE) multilayers ({DpAu/DMDPSE}n) membranes were used for modifying Au electrode to fabricate amperometric immunosensor. DpAu/DMDPSE multilayers were modified alternatively to form multiple membranes by layer-by-layer self-assembly technology. The sensitive steps of surface modification were characterized by cyclic voltammetric (CV) and electrochemical impedance spectroscopy (EIS), respectively. The immunoreaction between anti-carbofuran monoclonal antibody and carbofuran directly triggered a signal via different pulse voltammetry (DPV). Under the optimized conditions, a linear relationship between the relative change in peak current of DPV (%ΔI) and the logarithm of carbofuran solution was obtained in the range from 0.1 to 1.0 × 106 ng/mL with a detection limit of 0.06 ng/mL. The advantages of the immunosensor were exhibited in its wider linear range, better reproducibility, stability, selectivity and regeneration. Using lettuces, cabbages, green peppers, tomatoes, Chinese chives and strawberries as model samples, acceptable recovery of 82.0–109.2% was obtained. The proposed method was proven to be a feasible quantitative method for carbofuran analysis, which may open a new door for ultrasensitive detection of carbofuran residues in vegetables and fruits.
