Abstract
The nanoparticles present a range of characterization challenges that affect the detailed and appropriate characterization of nanoparticles. Thus understanding the problems faced during characterization of nanoparticles and selecting a suitable characterization technique are of utmost importance. Specifically, nanoparticle characterization is performed to assess the surface area and porosity, pore size, solubility, particle size distribution, aggregation, hydrated surface analysis, zeta potential, adsorption potential and shape, size of the interactive surface, crystallinity, fractal dimensions, orientation, intercalation and dispersion of nanoparticles and nanotubes in nano-composite materials. Several techniques can be used to determine nanoparticle parameters, including UV- visible spectroscopy, dynamic light scattering (DLS), scanning electron microscopy (SEM), powder X-ray diffraction and Atomic Force Microscope (AFM) and basically they have been specifically used in agriculture and medicine as antibacterial, antifungal and antioxidants. Antibacterial activity of synthesized ZnO nanoparticles was carried out for both gram positive and gram negative bacteria and its effect against Helicoverpaarmigeralarvae.
