rerio was high in the order of PVP-, PEG- and PVA- followed by bare-ZnO. The current investigation found that ZnO NPs dissolution and uptake are the major factors which cause the toxicity against adult as well as embryonic zebra fishes respectively....
The zinc ferrite synthesized was doped with 0.1 g in situ by polyvinyl alcohol (PVA), Polyvinyl Pyrrolidone (PVP) and Polyethylene glycol (PEG) respectively. The properties of the formulated nanoparticles were determined by various characterization techniques. The XRD confirmed the formation of a ...
