Graphical Abstract
  • . The average crystallite size of the synthesized ZnO NPs was calculated using the Scherrer equation: where D is the crystallite size, K is the shape factor, λ is the X-ray wavelength (1.54 Å for Cu Kα radiation), β is the full width at half maximum (FWHM) of the diffraction peak in radians, and θ is
  • wrinkled pattern, and it was found that the NPs average size was 72 nm. The presence of ZnO NPs on the surface was confirmed through EDX, which showed characteristic elemental peaks validating the composition (Figure 4a–d). Zeta potential The ZnO NPs synthesized using GP258 showed good stability as
