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.
Biofilm (Eco-Corona) Formation from Microplastics in Freshwater

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.
Ecotoxicological significance of bio-corona formation on micro/nanoplastics in aquatic organisms
This review examined the ecotoxicological significance of bio-corona formation on micro- and nanoplastics in aquatic organisms, exploring how protein and biomolecule coatings alter the bioavailability, toxicity, and environmental fate of plastic particles.
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.
Understanding the formation and influence of soil-typical eco-coronas on microplastics through laboratory and field incubation experiments
Researchers conducted laboratory and field incubation experiments to characterize eco-corona formation on microplastics in soil, finding that soil-derived organic matter including humic acids, proteins, and carbohydrates forms a coating that alters MP surface properties, transport behavior, and adsorption efficiency in terrestrial environments.
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.
Eco-Corona Formation on Photooxidized Plastics Exposed to Mixed Organic Matter
Researchers studied eco-corona formation on photooxidized plastic surfaces exposed to mixed organic matter, finding that weathering alters plastic surface chemistry in ways that significantly change how organic molecules adsorb and form corona layers.
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.
The chemical behaviors of microplastics in marine environment: A review
This review summarized interactions between microplastics and organic pollutants and metals in the marine environment, covering sorption behavior across polymer types, the role of degradation in altering sorption capacity, and global monitoring data on pollutant concentrations on marine plastics. The authors conclude that microplastic type, pollutant properties, and environmental conditions all strongly influence chemical accumulation on plastic surfaces.
A comparative study of microplastics under the influence of soil-typical eco-coronas through laboratory and field incubation experiments
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.
Interactions of microplastic debris throughout the marine ecosystem
Researchers synthesized evidence on how microplastics function as dynamic mixtures of polymers, additives, and adsorbed organic contaminants — forming an 'ecocorona' — and reviewed how chronic exposure reduces feeding, depletes energy reserves, impairs fecundity, and may alter ecosystem processes including carbon flux to the deep ocean.
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.
A comparative study of microplastics under the influence of soil-typical eco-coronas through laboratory and field incubation experiments
Researchers compared microplastic behavior under laboratory and field incubation conditions when eco-coronas — natural surface coatings of organic matter, proteins, and humic acids — were present on particles, assessing how these coatings modify microplastic hydrophobicity, transport, and toxicity to soil organisms.
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.
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.
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.
