Exploring the environmental and potential therapeutic applications of Myrtus communis L. assisted synthesized zinc oxide (ZnO) and iron doped zinc oxide (Fe-ZnO) nanoparticles

Multiwalled Carbon Nanotube/Fe-Doped ZnO-Based Sensors for Droplet Electrochemical Detection and Degradation Monitoring of Brilliant Green

“…The stretching frequency of Fe–O could be seen in the transmittance peak at 598 cm –1 . Results clearly demonstrated the incorporation of Fe into the ZnO hexagonal crystal, with its atoms vibrating at a lower frequency due to their lower weight than Zn atoms …”

“…FTIR spectroscopy was used to clearly demonstrated the incorporation of Fe into the ZnO hexagonal crystal, with its atoms vibrating at a lower frequency due to their lower weight than Zn atoms. 39 The SEM micrographs of pure ZnO and Fe−ZnO are displayed in Figure 2 along with corresponding EDX spectra. The particles are aggregated; however, a hexagonal growth pattern is visible at certain points.…”

Facile Green Synthesis of Zinc Oxide Nanoparticles with Potential Synergistic Activity with Common Antifungal Agents against Multidrug-Resistant Candidal Strains

“…Another study reported that surface plasmon vibrations of biogenic ZnO nanoparticles synthesized using aqueous Punica granatum leaf extract caused an absorbance peak at 382 nm, demonstrating the reduction of zinc nitrate hexahydrate into ZnO NPs [51]. The band gap energy of the synthesized ZnO nanoparticles was estimated using Tauc's plot method [52] and estimated to be 3.4 eV, as seen in Figure 3 [53]. Our findings are in accordance with those of Ramesh et al (2015), who reported that the indirect band gap energy of biogenic ZnO synthesized using Solanum nigrum leaf extract was 3.4 eV [54].…”

Tin Decorated Zinc Sulphide Nanoparticles for Photocatalytic Degradation of Bromophenol Blue Dye and Their Therapeutic Applications: A Kinetic and Thermodynamic Approach

“…Percentage DPPH Inhibition.-The 2,2-diphenyl-1-picryl hydrazyl (DPPH) reagent was used to assess the free radical scavenging activity of nanoparticles, with some modifications to Ahmad et al's approach. 26 From a 4 mg ml −1 stock solution, 10 μl of nanoparticles solution were combined with 190 μl of DPPH reagent. The absorbance was measured at 515 nm with a micro plate reader after 1 hour of incubation in the dark.…”
