“…Although a moderately diverse set of aquatic organisms populates the nano‐Ni toxicity database (i.e., fish, invertebrates, plants, a macroalga, microalgae, a yeast, fungi, bacteria, and a virus), amphibians have only been tested with 2, relatively atypical, forms of nano‐Ni (Ni 0 ‐coated and NiO‐coated nanoparticulate γ‐Al 2 O 3 ; Svartz et al 2017, 2019). Some of the more commonly tested freshwater and saltwater fish (e.g., fathead minnow [ Pimephales promelas ], sheepshead minnow [ Cyprinodon variegatus ], rainbow trout [ Oncorhynchus mykiss ] and filter‐feeding saltwater benthic invertebrates [blue mussel Mytilus edulis ]) are also absent from the dataset.…”

We reviewed the literature on toxicity of nanoparticulate nickel (nano-Ni) to aquatic organisms, from the perspective of relevance and reliability in a regulatory framework. Our main findings were 1) much of the published nano-Ni toxicity data is of low or medium quality in terms of reporting key physical-chemical properties, methodologies, and results, compared with published dissolved nickel studies; and 2) based on the available information, some common findings about nanoparticle (NP) toxicity are not supported for nano-Ni. First, we concluded that nanoparticulate elemental nickel and nickel oxide, which differ in chemical composition, generally did not differ in their toxicity. Second, there is no evidence that the toxicity of nano-Ni increases as the size of the NPs decreases. Third, for most organisms tested, nano-Ni was not more toxic on a mass-concentration basis than dissolved Ni. Fourth, there is conflicting evidence about whether the toxicity is directly caused by the NPs or by the dissolved fraction released from the NPs. However, no evidence suggests that any of the molecular, physiological, and structural mechanisms of nano-Ni toxicity differ from the general pattern for many metal-based nanomaterials, wherein oxidative stress underlies the observed effects. Physical-chemical factors in the design and conduct of nano-Ni toxicity tests are important, but often they are not adequately reported (e.g., characteristics of dry nano-Ni particles and of wetted particles in exposure waters; exposure-water chemistry).

Metal‐based nanoentities, apart from being indispensable research tools, have found extensive use in the industrial and biomedical arena. Because their biological impacts are governed by factors such as size, shape, and composition, such issues must be taken into account when these materials are incorporated into multi‐component ensembles for clinical applications. The size and shape (rods, wires, sheets, tubes, and cages) of metallic nanostructures influence cell viability by virtue of their varied geometry and physicochemical interactions with mammalian cell membranes. The anisotropic properties of nonspherical metal‐based nanoarchitectures render them exciting candidates for biomedical applications. Here, the size‐, shape‐, and composition‐dependent properties of nonspherical metal‐based nanoarchitectures are reviewed in the context of their potential applications in cancer diagnostics and therapeutics, as well as, in regenerative medicine. Strategies for the synthesis of nonspherical metal‐based nanoarchitectures and their cytotoxicity and immunological profiles are also comprehensively appraised.
