Introduction: Two immiscible liquids are combined to form emulsions, which are stabilized by an emulsifying agent to stop separation. Surfactants, which lower the interfacial tension between the two phases and facilitate easier mixing, are commonly used as emulsifying agents.

Abstract: The effects of surface coatings on the acute and long-term toxicity of six zinc oxide nanoparticles (ZnO-NPs) against the marine copepod Tigriopus japonicus were investigated in this work. Yet, the copepod’s antioxidant gene expression revealed that these variations were caused by the hydrodynamic size and ion dissolution. In acute testing, bare and hydrophobic particles …
