ClearThe Composition of the Eco-corona Acquired by Micro- and Nanoscale Plastics Impacts on their Ecotoxicity and Interactions with Co-pollutants
This review examines how the 'eco-corona' — a layer of environmental biomolecules adsorbing onto plastic particle surfaces — alters the toxicity, transport, and interaction with co-pollutants of micro- and nanoplastics, emphasizing that this biological coating fundamentally changes how plastics behave in living organisms.
Ecotoxicological significance of bio-corona formation on micro/nanoplastics in aquatic organisms

Toxicity of micro/nanoplastics in the environment: Roles of plastisphere and eco-corona
This review examines how microplastics and nanoplastics gain biological coatings in the environment: larger microplastics develop a "plastisphere" of microorganisms on their surface, while smaller nanoplastics get wrapped in proteins and organic matter forming an "eco-corona." Both coatings change how toxic the particles are to living organisms and humans. The review highlights that studying plastic particles without these coatings, as most lab experiments do, may underestimate or mischaracterize their real-world health risks.
Eco-corona formation and associated ecotoxicological impacts of nanoplastics in the environment
This review examines how nanoplastics interact with natural organic matter in the environment to form an 'eco-corona,' a coating of biomolecules on the particle surface that changes their behavior and toxicity. Researchers found that eco-corona formation alters nanoplastic stability, transport, and biological interactions in ways that can either increase or decrease their harmful effects on organisms. The study highlights the importance of considering these surface transformations when assessing the real-world environmental risks of nanoplastic pollution.
A critical review on the biological impact of natural organic matter on nanomaterials in the aquatic environment

Coronas of micro/nano plastics: a key determinant in their risk assessments
This review examines how micro- and nanoplastics develop surface coatings called coronas when they interact with biological and environmental substances. These corona layers, formed from proteins, organic matter, and other materials, can significantly change how plastic particles behave in the body and environment, affecting their uptake, distribution, and toxicity. The study suggests that understanding these surface coatings is essential for accurately assessing the real-world risks of plastic particle exposure.

This review examines how nanoplastics in aquatic environments interact with natural biomolecules to form an eco-corona coating that fundamentally changes their behavior and ecological impact. Researchers found that this biological coating alters the surface chemistry, transport, and toxicity of nanoplastic particles in ways that depend on environmental conditions. The study highlights that understanding eco-corona formation is essential for accurately assessing the real-world risks of nanoplastic pollution.
Interactions between micro(nano)plastics and natural organic matter: implications for toxicity mitigation in aquatic species
This review examines how natural organic matter found in water can reduce the harmful effects of micro- and nanoplastics on aquatic species. Researchers found that natural organic matter forms a coating called an eco-corona on plastic particles, which can decrease their toxicity to organisms like fish and water fleas. The findings suggest that the natural composition of waterways plays an important role in moderating the ecological impact of plastic pollution.

The development of eco-coronas on agricultural nanomaterials reduces their harmful impact: a review
This review examines how 'eco-coronas' — layers of soil biomolecules that form on agricultural nanomaterials including microplastics — affect the toxicity of those particles to crops and soil organisms. The eco-corona can reduce or modify the harmful impacts of nanomaterials by changing their surface chemistry. Understanding how eco-coronas develop on microplastics in soil helps predict their real-world environmental behavior, which may differ from laboratory studies using clean particles.
Unravelling protein corona formation on pristine and leached microplastics
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.

Aquatic organisms modulate the bioreactivity of engineered nanoparticles: focus on biomolecular corona
This review examines how aquatic organisms influence the bioreactivity of engineered nanoparticles through the formation of a biomolecular corona in environmental settings. Researchers found that biological molecules shed by organisms can coat nanoparticle surfaces and significantly alter their behavior, toxicity, and fate in aquatic ecosystems beyond what standard laboratory toxicity studies capture.
Environmental dimensions of the protein corona
Researchers reviewed how nanomaterials entering natural environments acquire an "eco-corona" — a coating of proteins and other biomolecules that alters how organisms recognize and interact with the particles — and called for targeted research into how this coating changes during food chain transfer and affects ecotoxicity.
Unravelling protein corona formation on pristine and leached microplastics
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.
Aggravated Visual Toxicity of Eco-Corona on Micro(Nano)Plastics in Marine Medaka (Oryzias melastigma)
Researchers studied how a natural coating of biomolecules, called an eco-corona, that forms on micro and nanoplastics in seawater affects their toxicity to the eyes of marine medaka fish. They found that the eco-corona actually worsened visual damage compared to bare plastic particles, causing more severe retinal injury and eye cell death. The study reveals that the real-world biological coating on ocean plastics can amplify rather than reduce their harmful effects on marine life.

This review examines how minerals, metals, and biological material that accumulate on marine plastic surfaces—collectively the eco-corona—affect plastic buoyancy, degradation rates, and interaction with marine organisms. The authors find that eco-corona formation is rapid and fundamentally alters plastic biogeochemistry, influencing which organisms encounter plastics and how toxic chemicals are transferred.

Interactions of microplastics throughout the marine ecosystem
This conceptual review developed the idea of microplastic as a complex, dynamic mixture that accumulates organic material and contaminants into an 'ecocorona', changing particles' bioavailability and toxicity over time. The authors examined evidence for how chronic microplastic exposure reduces feeding, depletes energy, and impairs fecundity and growth across marine species.
