Polystyrene nanoparticles (PS NPs) are considered an upcoming threat to marine ecosystems. When NPs encounter biological fluids, they are readily covered by a biomolecular coating, named the “protein corona”, which critically drives the biological fate and toxicity of NPs. Here we provide the first attempt to identify key components of protein coronas of charged amino- and carboxyl-functionalized (PS-NH2 and PS-COOH, respectively) PS NPs exposed to coelomic fluid (CF) of the Mediterranean sea… Expand
Interplay Between Nanoplastics and the Immune System of the Mediterranean Sea Urchin Paracentrotus lividus
The present study highlights for the first time the interplay between model nanoplastics, such as the carboxyl-modified polystyrene nanoparticles (PS-COOH, 60 nm) NPs and the coelomocytes of the seaExpand
The Crucial Role of Environmental Coronas in Determining the Biological Effects of Engineered Nanomaterials.
Molecular mechanisms triggered by pristine and environmental corona-coated ENMs are compared, including membrane adhesion, membrane damage, cellular internalization, oxidative stress, immunotoxicity, genot toxicity, and reproductive toxicity. Expand
Nanoplastics affect moulting and faecal pellet sinking in Antarctic krill (Euphausia superba) juveniles.
The presence of fluorescent signal in krill faecal pellets (FPs) confirmed the waterborne ingestion and egestion of PS-COOH at 48 h of exposure and changes in FP structure and properties were also associated to the incorporation of PS NPs regardless of their surface charge. Expand
Nanoplastics affect moulting and faecal pellet sinking in Antarctic krill (Euphausia superba) juveniles
Plastic debris has been identified as a potential threat to Antarctic marine ecosystems, however, the impact of nanoplastics (< 1 μm) is currently unexplored. Antarctic krill (Euphausia superba) is aExpand
Impact of nanoplastics on hemolymph immune parameters and microbiota composition in Mytilus galloprovincialis.
The results indicate that exposure to nanoplastics can impact on the microbiome of marine bivalves, and suggest that downregulation of immune defences induced by PS-NH2 may favour potentially pathogenic bacteria. Expand
Environmental dimensions of the protein corona
The emerging understanding of the importance of the dynamic and evolving protein corona composition in mediating the fate, transport and biological identity of nanomaterials in the environment is presented. Expand
Toxicity of Carbon, Silicon, and Metal-Based Nanoparticles to the Hemocytes of Three Marine Bivalves
The highest aquatic toxicity was registered for metal-based NPs, which caused cytotoxicity to the hemocytes of all the studied bivalve species, and the results highlighted different sensitivities of the used tested mollusc species to specific NPs. Expand
