“…The scanning electron microscope used for evaluating the morphology of the pure ZnO and Ag-doped ZnO samples are shown in the figure 2 with reference to Jayabarthy et al [12]. Pure ZnO shows the clusters of tiny particles and the 2% Ag-doped ZnO occurs like hexagonal wurtzite structures and moreover spherical in shape.…”

Highly Crystalline pure and Ag-doped ZnO nanoparticles were prepared using the inexpensive sol-gel synthesis method with the stimulation of transition metal ion surfactant. The prepared pure and Agdoped (Silver doped) ZnO nanoparticles were characterised by various sophisticated techniques like x-ray Diffraction (XRD), Scanning Electron Microscope (SEM), Dynamic Light scattering (DLS), Fourier Transform Infrared Spectroscopy (FTIR), UV-visible absorption, Photoluminescence (PL) and Zeta potential. The result indicates that the average grain size of the prepared nanoparticles was found to be a minuscule 24 nm with a commendable bandgap of 3.21 eV and 1.73 eV respectively. The hexagonal wurzite structures of pure and Ag-doped ZnO at room temperature confirmed the luminescence characteristics of the nanoparticles.

We report in this paper antibacterial activity of Ag-doped TiO2 and Ag-doped ZnO nanoparticles (NPs) under visible light irradiation synthesized by using a sol-gel method. Structural, morphological, and basic optical properties of these samples were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) spectrum, and UV-Vis reflectance. Room temperature X-ray diffraction analysis revealed that Ag-doped TiO2 has both rutile and anatase phases, but TiO2 NPs only have the anatase phase. In both ZnO and Ag-doped ZnO NPs, the hexagonal wurtzite structure was observed. The morphologies of TiO2 and ZnO were influenced by doping with Ag, as shown from the SEM images. EDX confirms that the samples are composed of Zn, Ti, Ag, and O elements. UV-Vis reflectance results show decreased band gap energy of Ag-doped TiO2 and Ag-doped ZnO NPs in comparison to that of TiO2 and ZnO. Pathogenic bacteria, such as Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli, were used to assess the antibacterial activity of the synthesized materials. The reduction in the viability of all the three bacteria to zero using Ag-doped ZnO occurred at 60 μg/mL of culture, while Ag-doped TiO2 showed zero viability at 80 μg/mL. Doping of Ag on ZnO and TiO2 plays a vital role in the increased antibacterial activity performance.

A facile, and novel construction strategy invented on electrochemical procedures for the assemblage of zinc oxide nanoparticles (ZnO NPs) with a multiwalled carbon nanotube modified carbon paste electrode (ZnO-MWCNTMCPE) to ascertain the fluoroquinolone drug-Moxifloxacin (MOX). The ZnO-MWCNTMCPE can significantly improve the electron transfer process and lessen the impedance of the surface of the electrode. Besides, the oxidation of MOX has remarkably enhanced on the modified electrode. Under the optimal experimental conditions, the empirical results exhibited that the oxidation peak current was linearly proportional to the concentration of MOX in the range of 1.0 × 10 À 7 to 2.4 × 10 À 6 mol L À 1 with a detection limit of 0.452 × 10 À 7 mol L À 1. To analyze the practicality of the MOX determination technique in real samples, the intended sensor manipulated for the adjudication of MOX in human urine specimens, and the results authenticated the explore of MOX with the highest accuracy. Further, the proposed sensor system exercised for the simultaneous evaluation of paracetamol (ACOP) and MOX, the DPV technique unveiled the well-separated peaks among ACOP (0.188 mV) and MOX (0.814 mV) with a peak separation (ΔE) of 626 mV in real samples. Therefore, the suggested system could sense and discover the MOX in the biological systems.
