Nanomaterials such as graphene oxide (GO) have potential for a myriad of industrial applications due to their physical, chemical, mechanical and structural properties. However, due to these unique attributes, assessing the toxicity of GO -- necessary to meet relevant regulatory requirements -- remains challenging. A study now seeks a robust, reliable methodology for evaluating the ecotoxicity of GO, using an alga (Raphidocelis subcapitata) and a shrimp species (Paratya australiensis) to evaluate exposure risk.
