Nickel 2 chloride hexahydrate nicl2 6h2o

A total of 21 individual uncoated and coated ZnO, CuO, MnO₂, NiO, Al₂O₃, CeO₂, TiO₂, and Fe₂O₃ MONPs were investigated in this study. The material purity ranged from 97.8 to 99+%, and the primary particle size ranged from 10 to 60 nm. Table 1 lists the catalog numbers (Cat#), the vendor, and the physicochemical characteristics of MONPs as provided by the manufacturer.
The study also included the uncoated bulk analogs of ZnO, CuO, MnO₂, NiO, Al₂O₃, CeO₂, TiO₂, and Fe₂O₃ (Table 2) and the dissolved metal analogs to evaluate the effects of particle size and solubility on the potential genotoxicity. ZnCl₂ (Cat#Z0152), CuCl₂ dihydrate (CuCl₂·2H₂O, Cat#C3279), manganese (II) sulfate monohydrate (MnSO₄·H₂O, Cat#M7899), nickel (II) chloride hexahydrate (NiCl₂·6H₂O, Cat#N6136), aluminum (III) chloride hexahydrate (AlCl₃·6H₂O, Cat#A0718) and cerium (III) chloride heptahydrate (CeCl₃·7H₂O, Cat#228931) were obtained from Sigma–Aldrich (Oakville, ON, Canada). The physicochemical characterization, the results of cell viability and DNA damage assay (as evaluated by comet assay) for ZnO NPs (Cat#US3580), CuO NPs (Cat#544868), TiO₂ NIST NPs (referred to as “uncoated TiO₂ NPs”), ZnO MPs (Cat#US1003M), CuO MPs (Cat#US1140M), TiO₂ MPs (Cat#US1017M), ZnCl₂ and CuCl₂ were previously reported [34 (link)] and are included in this study for comparison purposes.
