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.
The interaction of micro/nano plastics and the environment: Effects of ecological corona on the toxicity to aquatic organisms.
This review examines how the ecological corona — the layer of organic matter, proteins, and microbes that form on micro- and nanoplastic surfaces in water — affects their toxicity to aquatic organisms. The ecological corona can either increase or decrease toxicity depending on its composition, making real-world plastic hazard assessment more complex than laboratory tests with clean particles suggest.
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.
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.
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.
Interaction of nanoplastics with extracellular polymeric substances (EPS) in the aquatic environment: A special reference to eco-corona formation and associated impacts
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.

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.
Mechanisms of eco-corona effects on micro(nano)plastics in marine medaka: Insights into translocation, immunity, and energy metabolism
Researchers studied how eco-corona (biomolecule coatings that form on plastics in the ocean) affects the behavior of micro- and nanoplastics in marine medaka fish. They found that eco-corona facilitated the translocation of microplastics from the intestine to the liver and prolonged their retention time in larvae. The study suggests that naturally occurring biomolecules in marine environments can enhance the movement and toxic effects of plastic particles in fish.

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.
A critical review on the biological impact of natural organic matter on nanomaterials in the aquatic environment
This review examines how natural organic matter in aquatic environments forms an ecological corona on the surface of nanomaterials, influencing their behavior, toxicity, and environmental fate. Researchers found that eco-corona formation can either increase or decrease the hazards posed by nanomaterials to aquatic organisms, making it a critical factor for environmental risk assessment.
A Review of Eco-Corona Formation on Micro/Nanoplastics and Its Effects on Stability, Bioavailability, and Toxicity
When microplastics and nanoplastics enter water, natural substances like humic acid coat their surfaces, forming what scientists call an "eco-corona." This coating changes how the plastic particles behave, including how they clump together and how easily organisms absorb them. Importantly, the eco-corona can actually reduce some of the toxic effects of these plastic particles, such as growth problems and oxidative stress.
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.
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.

Nanoplastics and Protein Corona - Investigating the Corona Structure and their Biological Impacts
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.

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.

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.
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.
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.
Assessment on interactive prospectives of nanoplastics with plasma proteins and the toxicological impacts of virgin, coronated and environmentally released-nanoplastics
Researchers found that nanoplastics quickly coat themselves in blood proteins, forming a multi-layered "corona" that changes the proteins' shape and makes them biologically harmful; these protein-coated nanoplastics caused more DNA and cell damage in human blood cells than bare nanoplastics. The study highlights the need to regulate nanoplastics in medical products and better understand how they accumulate in the body.
