Fabrication of Resistive E. coli Biosensor Based on ZnO Nanorods and Nanoparticles
In this paper, a biosensor has been fabricated using ZnO nanorods and nanoparticles to detect different concentrations of the E. coli bacteria. The innovation of this paper lies in design and fabrication of the resistive type E Coli bacteria sensor. To make this biosensors, printed circuit board based electrodes are designed and made in an interdigitated shape. Both hydrothermal and drop cast m...
متن کاملEmbedded ZnO nanorods and gas-sensing properties
Regular hexagonal embedded ZnO nanorods were successfully prepared by a simple hydrothermal method. The addition of urea as a homogeneous precursor was found to play a vital role in the embedding of secondary nanorods. The nanostructures were characterized by XRD, SEM, and EDS. The gas-sensing properties of secondary grown embedded nanorods were reported for formaldehyde, ethanol, methanol, ace...
متن کاملSYNTHESIS OF ZnO NANORODS BY HYDROTHERMAL METHOD FOR GAS SENSOR APPLICATIONS
ZnO nanorods with different sizes and shapes have been successfully synthesized via a simple hydrothermal route, using zinc acetate and Cetyltriammonium bromide (CTAB) as the reactants. The thick films of as prepared ZnO were prepared by screen-printing technique in desired pattern. The films are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission elect...
متن کاملPatterning of oxide-hardened gold black by photolithography and metal lift-off
A method to pattern infrared-absorbing gold black by conventional photolithography and lift-off is described. A photo-resist pattern is developed on a substrate by standard photolithography. Gold black is deposited over the whole by thermal evaporation in an inert gas at 1 Torr. SiO2 is then deposited as a protection layer by electron beam evaporation. Lift-off proceeds by dissolving the photor...
متن کاملIron Ion Sensor Based on Functionalized ZnO Nanorods, 2012, Electroanalysis
In this work, we are presenting an iron ion (Fe 3+ ) potentiometric sensor based on functionalized ZnO nanorods with selective ionophore (18 crown 6). Zinc oxide nanorods with a diameter of about 100 to 150 nm and 1μm in length were grown on gold coated glass. The selective Fe 3+ ionophore sensor with highly aligned ZnO nanorods has given high sensitivity, acceptable selectivity, reproducibilit...
