A Raman imaging study of the ecocorona surrounding microplastics in aquatic environments
AI summary Read the abstract
This Raman imaging study characterized the eco-corona that forms around microplastics in natural water, identifying the organic molecules and biomolecules that coat plastic particles when they enter aquatic environments. Understanding the eco-corona is important because it alters the surface properties of microplastics and can influence how organisms interact with and ingest them.

A Raman imaging study of the ecocorona surrounding microplastics in aquatic environments
AI summary Read the abstract
This conference abstract describes a Raman imaging study of the ecocorona—the layer of biological and environmental molecules—surrounding microplastic particles in aquatic environments. The research aims to characterize how this surface coating forms and changes in polar aquatic settings, with implications for how microplastics interact with organisms and transport contaminants.
The interaction of micro/nano plastics and the environment: Effects of ecological corona on the toxicity to aquatic organisms.
AI summary Read the abstract
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.
The Composition of the Eco-corona Acquired by Micro- and Nanoscale Plastics Impacts on their Ecotoxicity and Interactions with Co-pollutants
AI summary Read the abstract
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.
Eco-corona formation on aminated nanoplastics interacted with extracellular polymeric substances from bloom-forming cyanobacteria: Insightful mechanisms with DFT study
AI summary Read the abstract
This study examined how tiny plastic particles with amino surface groups interact with substances released by algae in water, forming a coating called an "eco-corona." Understanding how nanoplastics behave and clump together in natural water environments is important because it affects how easily they move through ecosystems and potentially into drinking water sources.
Toxicity of micro/nanoplastics in the environment: Roles of plastisphere and eco-corona
AI summary Read the abstract
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.
