Core Tip

Core Tip: Eco-coronas form spontaneously on micro- and nanoplastics in natural environments, giving them new bioactive surfaces that influence their interactions with living systems. By modifying the behavior of plastics in the gut, influencing microbial composition, immune responses, and barrier integrity, eco-coronas appear as a critical yet insufficiently explored factor in evaluating the health risks associated with plastic ingestion. Understanding these transformations is key to advancing both environmental and gastrointestinal toxicology.
