Nanoplastics impact on marine biota: A review
Environmental Pollution, 2021 Emerging contaminants, such as nanoplastics, are gaining a vast interest within the scientific community. Most of the plastic debris found in the marine environment originates from land-based sources, and once in the marine environment, plastic can be ...

Modular Molecular Nanoplastics
ACS Nano, 2019In view of their facile fabrication and recycling, functional materials that are built from small molecules ("molecular plastics") may represent a cost-efficient and sustainable alternative to conventional covalent materials. We show how molecular plastics can be made robust and how their (nano)structure can be tuned via modular construction.

Here we show that the direct binding of functionalized polystyrene chains can trigger biochemically relevant structural changes in DNA helices. For the stable association of the plastic and the biomolecule, the presence of the positively charged functional groups was found to be essential, which form strong Coulombic interactions with the phosphate ...

Detection methods of micro and nanoplastics
2023Plastics and related contaminants (including microplastics; MPs and nanoplastics; NPs) have become a serious global safety issue due to their overuse in many products and applications and their inadequate management, leading to possible leakage into the environment and eventually to the food chain and humans.

Science of The Total Environment, 2022
Although plastics are widely distributed in soil environments, few studies have assessed their effects on different test species. In this study, the responses (adsorption or internalization) of two green algal species (Chlorococcum infusionum and Chlamydomonas reinhardtii) to nanoplastics in soil were evaluated via microscopic analysis for nine weeks ...

Open questions about the potential effects of nanoplastic particles have driven researchers to a frontier of measurement science, where they seek answers without the full support of metrological standards. Documentary and material standards improve the reliability of measurement results but are slow to develop, while researchers are eager to explore ...

Environmental Science & Technology
Nanoplastics and antibiotics frequently co-occur in aquatic environments, and their interactions could alter nanoplastics' surface properties, affecting nanoplastics aggregation, fate, and ecotoxicity. However, the mechanisms driving antibiotics-induced nanoplastics aggregation under environmentally relevant conditions remain unclear.

Nanoplastics in the Environment
2018There has been an increasing awareness of the potential ecotoxicological consequences of the growing presence of plastic materials in the environment. Among these, due to their inherent physical and chemical characteristics, microplastics have received special attention, though smaller particles, defined as nanoplastics, could have more pervasive ...
