“…Aggregation also correlates positively with concentration due to increased number of particle-particle interaction per unit volume (Fairbairn et al 2011; Miller et al 2010), which in due course results in reduced surface area and dissolution potential of NPs (Baker et al 2014). In similar studies by Gong et al (2011) and Oukarroum et al 2015, NiO NPs also form aggregates with a wide size distribution and about 0.14% ionic Ni was released when NiO NPs were added into seawater. The surface charge of NPs determines particle’s stability in the solvent against agglomeration and thus plays an important role on the interaction with biological systems (Clogston and Patri 2011).…”

In this study, the effects of exposure to engineered nickel oxide (NiO 40–60 nm) and cobalt oxide (CoO <100 nm) nanoparticles (NP) were investigated on Artemia salina. Aggregation and stability of the aqueous NP suspensions were characterized by DLS and TEM. Acute exposure was conducted on nauplii (larvae) in seawater in a concentration range from 0.2 to 50 mg/L NPs for 24 h (short term) and 96 h (long term). The hydrodynamic diameters of NiO and CoO NPs in exposure medium were larger than those estimated by TEM. Accumulation rate of NiO NPs were found to be four times higher than that of CoO NPs under the same experimental conditions. Examinations under phase contrast microscope showed that the nanoparticles accumulated in the intestine of artemia, which increased with increasing exposure concentration. Differences were observed in the extent of dissolution of the NPs in the seawater. The CoO NPs dissolved significantly while NiO NPs were relatively more stable. Oxidative stress induced by the NP suspensions was measured by malondialdehyde assay. Suspensions of NiO NPs caused higher oxidative stress on nauplii than those of CoO NPs. The results imply that CoO and NiO NPs exhibit toxicity on artemia (e.g., zooplankton) that are an important source of food in aquatic food chain.

“…This might be due to the presence of Ni 2+ ions in the polymer composites. Mostly, NiO NPs themselves have toxicity because soluble fraction of Ni free ionic behavior may lead to cellular toxic effect . As, the synthesized novel green composites could reduce their toxic level due to presence of herbal plant extract as evidence from Fig.…”

“…Nevertheless, very few reports are available on PMMA/NiO composite for biological application due to their toxic nature of NiO. Our goal is to reduce the toxicity of NPs by using herbal plant into polymer matrix . Considering the significance of prepared polymer nanobiocomposites on their effective investigation of cytotoxicity studies are very rare.…”

We report the intrinsic biological properties of nickel oxide nanoparticle (NiO NPs) encapsulated Nardostachys jatamansi DC-based polymethyl methacrylate (PMMA) via free radical polymerization technique. A simple and cost effective NiO NPs was adapted to synthesize via sol-gel/co-precipitation method to afford crystalline structures of NPs and it was confirmed by X-ray diffraction (XRD) patterns (2θ at 38.78 [111] and 62.66 [220]). The results demonstrated that the sparingly loaded NiO NPs onto composites exhibited the lowest crystallinity, which led to better dispersion into the polymer matrix and also observed by scanning electron microscopy (SEM) and atomic force microscopy (AFM). ATR-IR enunciate the functional groups of polymer nano-biocomposites attributed at 1730 cm −1 ( C=O), 1446 cm −1 ( CH 3 -asymmetric deformation), 1162 cm −1 ( C-N), and 822 cm −1 ( C-H), which were found to be good agreement for the formation of polymer composites and further confirmed their structural identification by NMR, fluorescence spectroscopy and UV-vis spectroscopy. This hybrid nano-biocomposite has been utilized for antimicrobial studies using a gram positive and gram-negative bacteria and showed better results on minimum bactericidal concentration (MBC) assay against Micrococcus luteus, Staphylococcus epidermidis, Yersinia enterocolitica, and Klebsiella pneumoniae. In addition, cell morphology and proliferation were monitored by fluorescence microscopy. The MTT assay results showed that the nano-biocomposites possessed significantly low cytotoxicity against human keratinocyte cell lines (HaCaT).

“…In the environment, nickel nanoparticles appear to pose a low ecological risk to aquatic organisms [258][259][260][261][262]. In the Ispas et al [255] study, zebrafish were treated with three different nickel nanoparticle sizes resulting in less toxicity than the larger soluble nickel.…”

Nickel (Ni) metal and Ni compounds are widely used in applications like stainless steel, alloys, and batteries. Nickel is a naturally occurring element in water, soil, air, and living organisms, and is essential to microorganisms and plants. Thus, human and environmental nickel exposures are ubiquitous. Production and use of nickel and its compounds can, however, result in additional exposures to humans and the environment. Notable human health toxicity effects identified from human and/or animal studies include respiratory cancer, non-cancer toxicity effects following inhalation, dermatitis, and reproductive effects. These effects have thresholds, with indirect genotoxic and epigenetic events underlying the threshold mode of action for nickel carcinogenicity. Differences in human toxicity potencies/potentials of different nickel chemical forms are correlated with the bioavailability of the Ni2+ ion at target sites. Likewise, Ni2+ has been demonstrated to be the toxic chemical species in the environment, and models have been developed that account for the influence of abiotic factors on the bioavailability and toxicity of Ni2+ in different habitats. Emerging issues regarding the toxicity of nickel nanoforms and metal mixtures are briefly discussed. This review is unique in its covering of both human and environmental nickel toxicity data.
