Abstract
Numerous studies have shown zinc oxide nanoparticles (ZnO NPs) inducing zebrafish embryotoxicity. However, due to the complexity and heterogeneity of published data, the relationship between exposure dose and their toxicity is confounded. In this study, we present a rigorous approach for extracting and analyzing pertinent knowledge from the originally published evidence on embryotoxicity of ZnO NPs. The available 17 studies were determined by random effects model of meta-analysis. After exposure dose subgroup analysis from 0.5 to 50 mg/L, we found that ZnO NPs decreased the hatching rate of zebrafish embryo at lower dose of 0.5 mg/L (standardized mean difference (SMD) = − 2.20, 95% CI = [− 3.71, − 0.68]). Moreover, we summarized the potential mechanisms of ZnO NP-induced embryotoxicity and found that particle form or released Zn ions form nanoparticles entered into embryo and induced oxidative stress, inflammation and apoptosis. Our results help people get to know more about nano-embryotoxicity and provide a criterion for future studies to develop nanoparticles that are safe by design.
期刊介绍:
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
