Detection methods of micro and nanoplastics

2023
Plastics 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.

Soil algae as a potential carrier for nanoplastics: Adsorption and internalization of nanoplastics in algal cells

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 ...

Nanoplastics Alter DNA

Nano Letters
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 ...

Interactions between Nanoplastics and Antibiotics: Implications for Nanoplastics Aggregation in Aquatic Environments

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.

Nanoplastic Standards

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 ...

Nanoplastics in the Environment

2018
There 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 ...

Nanoplastics can build themselves

The Journal of Physical Chemistry Letters
To understand nanoplastics through modeling, e.g., to assess their toxicity and environmental impact, reliable starting structures are required. In this study, we present a new approach to generate nanoplastic particles from classical molecular dynamics simulations.

Interactions of insects with micro- and nanoplastics: A review

Science of The Total Environment
Despite the rapid spread of plastic pollution, and particularly micro- and nanoplastic pollution, a comprehensive systematic review of microplastic distribution and toxicology in terrestrial and aquatic insects has yet to be conducted. This leaves a significant gap in contrast to the well-documented impacts on marine and vertebrate lineages.
