Unraveling the interfacial fate of nanoplastics in soil: proteomics and molecular dynamics decipher the protein corona governed by surface functionalization
AI summary Read the abstract
This study used proteomics and molecular dynamics simulations to examine how soil proteins coat nanoplastics — forming what is called a 'protein corona' — and how that coating changes depending on the nanoplastic's surface chemistry. The protein corona affects how nanoplastics move through soil and interact with living organisms, making this research important for understanding the true environmental fate of nanoplastics once they enter land ecosystems.
Interactions between nanoplastics and soil proteins can profoundly influence their environmental behavior and transformation in terrestrial environments.

Mobility of soil-biodegradable nanoplastics in unsaturated porous media affected by protein-corona
AI summary Read the abstract
Biodegradable plastic mulches used in agriculture can release nanoplastics into soil, and this study shows that a protein corona — a coating of soil proteins — affects how those nanoplastics move through unsaturated soil layers. The finding matters because biodegradable labels do not guarantee that plastic particles stay put; they can still migrate toward groundwater depending on soil chemistry.
Unravelling protein corona formation on pristine and leached microplastics
AI summary Read the abstract
Researchers found that when microplastics encounter proteins in biological fluids, they get coated in a "protein corona" that depends heavily on the plastic's chemical additives, surface area, and how much it has been weathered in the environment. This coating changes how microplastics behave in the body, meaning toxicity studies need to account for these real-world surface changes.
Unravelling protein corona formation on pristine and leached microplastics
AI summary Read the abstract
When microplastics enter biological fluids or protein-rich environments, proteins coat their surface to form a 'protein corona' that changes how the particles behave in living systems. This study explored how the physical and chemical properties of pristine versus weathered microplastics influence corona formation, finding that surface changes caused by environmental aging significantly alter protein binding. Understanding this process matters because the protein coat — not the plastic itself — is often what cells and organisms first encounter.
Nanoplastics and Protein Corona - Investigating the Corona Structure and their Biological Impacts
AI summary Read the abstract
This PhD thesis investigated how proteins from biological fluids coat the surface of nanoplastics, forming a 'protein corona' that changes how nanoplastics interact with cells and tissues. The protein corona is important because it alters the biological behavior of nanoplastics once they enter the body, potentially affecting how harmful they are.
A comparative study of microplastics under the influence of soil-typical eco-coronas through laboratory and field incubation experiments
AI summary Read the abstract
Researchers compared the formation and properties of soil-typical eco-coronas on microplastics through both laboratory incubation and real-world field experiments, examining how natural organic matter coatings of proteins, carbohydrates, and humic acids alter microplastic surface hydrophobicity and transport behaviour. The study found that eco-corona composition significantly influences how microplastics move through terrestrial environments and interact with soil organisms.
