    Abstract In this study, an effective electrochemical method was successfully developed to produce polyaniline/multiwalled carbon nanotubes nanocomposite on interdigitated platinum microelectrodes for the enhancement of biosensing performance. Morphology and structure of nanocomposite were investigated by field emission scanning electron microscopy and ultraviolet–visible spectroscopy. Fourier transform infrared spectroscopy technique was used to identify the presence of polyaniline/multiwalled carbon nanotubes on the surface of microelectrodes. IgG polyclonal antibodies against Japanese encephalitis virus (JEV) were immobilized onto nanocomposite-modified microelectrodes, acting as an electrochemical immunosensor for label-free detection of JEV antigens. Results showed that the linear detection range of the immunosensor for JEV antigens was 2–250 ng/mL. The electrochemical impedance spectroscopy analysis also indicated that a negligible response was found when the immunosensor exposed to non-specific molecules. This work showed the potential use of polyaniline/multiwalled carbon nanotubes nanocomposite in the platform of electrochemical immunosensors for label-free detection of pathogens and small biomolecules.

    Abstract We synthesized ZnO architectures, including nanorods, porous plates, and flower-like architectures by using different types of zinc salts and surfactants in a hydrothermal process. Photoluminescence spectra demonstrate green emission enhancement owing to both oxygen vacancies and acceptor centers by the passive occupation of sodium ions on the ZnO surfaces. Gas-sensing devices are reported with an enhanced sensing response of nanorods of up to 13 times to NO₂ gas, with respect to ZnO belt-like architectures. In addition, we also measured a high performance in photocatalytic degradation of dye molecules. The correlation between structural defects and gas-sensing properties as well as photocatalytic activity was also discussed.

    Abstract Pure and Au-decorated sub-micrometer ZnO spheres were successfully grown on glass substrates by simple chemical bath deposition and photoreduction methods. The analysis of scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images, energy-dispersive X-ray spectroscopy (EDS), UV-vis absorption, and photoluminescence (PL) spectra results were used to verify the incorporation of plasmonic Au nanoparticles (NPs) on the ZnO film. Time-resolved photoluminescence (TRPL) spectra indicated that a surface plasmonic effect exists with a fast rate of charge transfer from Au nanoparticles to the sub-micrometer ZnO sphere, which suggested the strong possibility of the use of the material for the design of efficient catalytic devices.
