    ABSTRACT: tIn this study we deposited new, ternary thin films of copper aluminum oxide with p-type and n-typebehavior using RF magnetron sputtering for use as chemical gas sensors. p-Type materials are known tobe good catalysts and can be combined with the well-known n-type materials for chemiresistive sensorsapplication. Copper aluminum oxide in the delafossite phase CuAlO2is a ternary oxide that has generatedinterest as a transparent p-type conducting material, while in the spinel phase CuAl2O4is known to ben-type. We demonstrated that thin films of copper aluminum oxide with the proper resistance can besuccessfully applied as p- and n-type resistive gas sensors for ozone detection. We have studied thesputtering deposition conditions from a CuAlO2sintered target by changing the substrate temperature ininert Ar atmosphere. In addition, post-deposition annealing in O2atmospheres was also tested. XRD, SEMand Raman investigations were used to characterize the thin films. Selected films with mixed phases ofCuAlO2, CuAl2O4and CuO were tested for gas sensing as resistive chemical sensors, showing promisingresults with ozone, acetone and ethanol.

    ABSTRACT: A Pt/AlGaN/GaN heterostructure field-effect transistor (HFET), based on sensitization, activation, and electroless plating (EP) deposition approaches, is fabricated and studied. Utilizing the sensitization and activation processes, a dense and uniform Pd seed layer could be implanted on the AlGaN layer prior to Pt-gate formation. In addition, a dense Pt-gate morphology and excellent Schottky contact properties are obtained. This causes significant improvement in DC performance and thermal stabilities as compared with a thermal evaporation (TE)-based one. For a used gate dimension of 1 × 100 μm2, the lower gate leakage current of 0.9 (8.4) nA, higher maximum extrinsic transconductance of 90.1 (52.1) mS/mm, and maximum drain saturation current of 325 (178) mA/mm are found for an EP Pt-gate HFET at 300 (600) K. Moreover, as a hydrogen gas sensor, the maximum drain current response (13.7%), high on/off ratio (8 × 105), and fast response (28 s) and recovery (36 s) time constants in 10,000, 50, and 5 ppm H2/air gases are obtained at 400 K, respectively. Therefore, the studied EP Pt-gate HFET shows promise for a high-performance electronic device and hydrogen gas sensing applications.

    ABSTRACT: A novel surfactant sensitized fluorescent chemosensor for safranine T (ST) based on calixarene-1,3-diacyl hydrazone (CADH) in sodium dodecyl sulfate (SDS) medium was investigated. The fluorescence intensity of CADH was quenched by ST due to the formation of weak fluorescent inclusion complex (ST-CADH), and the fluorescence quenching (ΔF = FCADH − FST-CADH) was sensitized in SDS. Under the optimal conditions, the linear range of calibration curve for the determination of ST was 0.02–3.00 μg/m and the detection limit estimated 0.015 μg/mL with RSD 2.2% (n = 3, c = 1.0 μg/mL). The mechanism of determination was discussed with the fluorescence quenching type, the inclusion of CADH with ST and surfactant sensitized effect. This method has been applied for the detection of ST in real samples with satisfactory results.

    ABSTRACT: A simple graphene quantum dots (GQDs)-based fluorescence sensing system was developed for rapid, sensitive and low-cost detection of ascorbic acid (AA) in the presence of copper ions. Due to the efficient electron-transfer between GQDs and Cu2+ ions, the fluorescence of GQDs was greatly quenched by Cu2+ ions. Upon addition of ascorbic acid, Cu2+ was reduced to Cu+ and the interaction of Cu2+-GQDs was destroyed, which inhibit the quenching and thus leading to fluorescence recovery of GQDs. The detection process is ultrafast and can be completed within 5 min. The linear response range of AA was obtained from 0.3 μM to 10 μM. The detection limit was as low as 94 nM, which was comparable to or even better than other reported assays. In addition, this sensing system also showed good selectivity for detecting AA in the presence of different physiological molecules and inorganic ions. Finally, the proposed sensing system was successfully applied to assay AA in real samples with satisfactory results.

    ABSTRACT: A novel method was developed to design highly sensitive ethanol gas sensor based on the mechanism of ethanol quasi molecular imprinting. SnO2 nanoparticles E and W were prepared by incorporating liquid ethanol which is the tested objective gas with deionized water thermal method and pure deionized water thermal method respectively. SnO2 nanoparticle films WW and EW for ethanol gas sensor were obtained by mixing pure deionized water with the as-prepared powders W and E, and WE and EE were prepared by mixing liquid ethanol with W and E powders respectively. The ethanol gas sensing properties of these films were evaluated. Testing results reveal that the sensor SEE based on film EE which was fabricated by mixing liquid ethanol with E nanoparticles exhibits the most excellent sensing performance to ethanol gas and the response descended in the order of SWE, SEW and SWW. It proves that the introduced objective gas in the procedure of device fabrication plays a very important role for design a highly sensitive gas sensor. In addition, we consider that pore diameter of about 4.3 nm may be the critical size for the smooth adsorption and desorption of ethanol gas.

    ABSTRACT: AlPO4-5 zeolite was successfully employed in a resistance type humidity sensor. AlPO4-5 zeolite humidity sensor was fabricated by coating nanosized materials over interdigitated electrodes. The sensor shows good linearity over a relative humidity (RH) range from 11% to 95%. At the frequency of 100 Hz, response and recovery time are both about 2 s, and the maximum hysteresis is <3%. In nanoscale confinement range, the sorbed water quantity in AlPO4-5 channels is exceptionally large and the water sorption phenomenon looks like “capillary condensation” phase transition. The complex impedance at different RH was investigated to understand the sensing mechanism. The results indicate the potential application of AlPO4-5 zeolite for fabricating high-performance humidity sensors.

    ABSTRACT: A simple and sensitive label-free electrochemical biosensor for nimodipine was fabricated by using nitrogen-doped graphene (NGE) modified electrode. The surface morphology and electron transfer behavior of the modified electrodes were studied by scanning electron microscopy and electrochemical impedance spectroscopy, respectively. The electrochemical behaviors of nimodipine at the modified electrodes were investigated by using cyclic voltammetry. On the basis of the excellent electrocatalytic activity of NGE, an obvious cathodic peak of nimodipine could be caused at the NGE modified glassy carbon electrode (GCE), moreover, the electrochemical signal was greatly enhanced compared with the undoped graphene modified GCE. Under the optimized conditions, the present sensor showed excellent performances for nimodipine detection including wide linear range of 0.02–3 μM, low detection limit (9.1 nM), good selectivity to the general coexisted interferences, etc. The proposed biosensor was also successfully applied to validate its capability for the analysis of nimodipine in tablets. The work would promote the potential application of NGE as an excellent material in fabricating electrochemical sensors for chemical or biochemical analysis.

    ABSTRACT: This work describes a new, simple, and fast electrochemical method for simultaneous determination of captopril (CAP) and hydrochlorothiazide (HCT) using a boron-doped diamond (BDD) electrode associated with batch-injection analysis with multiple-pulse amperometric (BIA–MPA) detection. A sequence of potential pulses was selected in such a way that HCT was selectively detected at +1.4 V/50 ms and both (HCT + CAP), were detected at +1.8 V/50 ms. CAP was quantified without interference of HCT by subtracting the currents detected at +1.8 V and +1.4 V (using a correction factor). The proposed BIA method requires minimal sample manipulation (dissolution and dilution in electrolyte) and the simultaneous determination is achieved with a single injection step of 150 μL of a sample solution (100 injections h−1). The results obtained with the BIA method were compared to those obtained by capillary electrophoresis and similar results were obtained (at 95% of confidence level). A simple and rapid test for detecting the presence or absence of electroactive interferents was also proposed (fast screening test).

    ABSTRACT: Protozoan Trypanosoma cruzi is the etiological agent of Chagas disease, which needs urgent progress in its immunological diagnosis. Surface plasmon resonance (SPR) is a promising technique for the development of immunosensors with biomedical applications. In this work, a SPR-based immunosensor has been developed by the first time for real time and label free immunoassay for detection of anti-T. cruzi antibodies in serum samples. T. cruzi antigen was successfully immobilized on a SPR sensor chip via activated mixed self-assembled monolayer (SAM) of 3-mercaptopropionic acid (3-MPA) and 11-mercaptoundecanoic acid (11-MUA), by amide coupling. After the sensor construction, a pool of human sera infected with T. cruzi was added to its surface and the antibodies were detected in sera diluted up to 1280 times, indicating excellent sensitivity of the technique for detection of antigen–antibody interaction. The addition of a pool of negative human serum at dilutions lower than 1:160 to the sensor surface was accompanied by a null or very low response. Then, the following operational parameters of the immunoassay were optimized and defined: time of immobilization and antigen concentration at 20 min and 30 mg mL−1, serum dilution at 1:320, preventing of nonspecific bindings with solution of BSA 1.0% and surface regeneration by injection of SDS 1.0%. The immunoassay, here termed SPRCruzi, showed high capability in the discrimination of positive and negative sera, including those infected with other pathogens usually sources of false positives results in conventional serodiagnosis. Therefore, the proposed immunosensor was successfully developed and the immunoassay allowed a simple, effective, faster and specific detection of anti-T. cruzi antibodies, which represents an encouraging field for the progress of the diagnosis of Chagas disease.

    ABSTRACT: Detection of tumor markers is important for cancer diagnosis. Field effect transistor (FET) has been recognized as a powerful technique for label-free, sensitive, real-time, and multifunctional biosensing. Here, we developed FET biosensors that allow the label-free detection of cytokeratin fragment 21-1 (CYFRA 21-1) and neuron-specific enolase (NSE), useful tumor markers for lung cancer type differentiation. It was found that the FET biosensor was capable of quantitatively detecting these tumor markers in both phosphate-buffered saline and human serum. Additionally, we developed a multianalyte FET biosensor for the selective multiplexed detection of CYFRA 21-1 and NSE at the same time, by integrating two antibody types on the same chip, providing a step towards the realization of sensor arrays. The multianalyte FET biosensor, as described herein, will help for lung cancer differential diagnosis with advantages of simple and rapid detection procedures, low sample consumption, and low cost.

    ABSTRACT: Facile and stable nanocomposites, carbon nanocages (CNCs)-reduced graphene oxide (RGO), were developed via one-pot in situ solvothermal reaction in this study. Transmission electron microscope, scanning electron microscope, X-ray diffraction, Raman spectroscopy, energy dispersive X-ray spectroscopy, atomic focus microscope, N2 adsorption/desorption isotherms, thermogravimetric analysis and Fourier-transform infrared were performed to characterize the CNCs-RGO hybrid material. The electrochemical detections of catechol (CC) and hydroquinone (HQ) were investigated by means of cyclic voltammetry (CV) and differential pulse voltammetry (DPV). The excellent electrocatalytic activity and reversibility have been shown on the modified electrode toward oxidation of both CC and HQ in 0.04 M acetate buffer solution (pH = 4.0). The relationship between the oxidation peak current of CC and its concentration was linear over the range from 1 to 400 μM in the presence of 100 μM HQ, and the linear relationship between the oxidation peak current of HQ and its concentration can be obtained range from 1 to 300 μM in the presence of 100 μM CC. The detection limits (S/N = 3) for CC and HQ were 0.40 and 0.87 μM, respectively.

    ABSTRACT: This paper reports on the design, fabrication, characterisation and deployment of a multi-measurand optical fibre sensor (MMS) that is capable of simultaneously monitoring strain, temperature, refractive index and cross-linking chemistry. The sensor design is based on the extrinsic fibre Fabry–Perot interferometer. A feature of this sensor system is that a conventional multi-channel fibre-coupled near-infrared spectrometer is used to monitor the four independent parameters. The issues relating to the measurement resolution of the individual sensors and the associated interrogation equipment are discussed. The MMS was embedded in between the fourth and fifth plies of an eight-ply E-glass plain-weave fabric. A commercially available thermosetting epoxy/amine resin system was used to impregnate the fabric layers manually. The laminated preform was vacuum-bagged and cured in an autoclave. The following parameters were monitored: the depletion rates of the epoxy and amine functional groups in the resin system; the temperature in close proximity to the “chemical sensor”; the evolution of strain; and the refractive index of the resin system. The effect of post-processing on the output from the embedded optical fibre sensors is also considered.

    ABSTRACT: Recently, the development of convenient and fast chemical method for sensing benzo(a)pyrene (BaP) has drawn significant attention. We report a simple, ultrasensitive and inexpensive SERS protocol, which based on the facile synthesis of inositol hexaphosphate (IP6) stabilized gold nanoparticles (Au NPs), to detect trace BaP in the edible oil without tagging. Au NPs are modified by IP6 certainly increase hydrophobic capability of such SERS substrate to catch BaP molecules from bulk oil. This SERS-based method for detecting BaP could be expected to have wide-range applications in many areas such as analysis of trace BaP in edible oil.
