Unravelling the in vivo biotoxicity of a green-biofabricated graphene oxide–microplastic hybrid mediated by proximal intrinsic atomic interactions
AI summary Read the abstract
Researchers found that when graphene oxide, a nanomaterial used in many products, combines with polystyrene microplastics, the hybrid material is more toxic to zebrafish embryos than either substance alone. The increased toxicity was driven by oxidative stress, where the atomic interactions between the two materials amplified cell damage. This study highlights how microplastics can interact with other nanomaterials in the environment to create unexpected health risks.
GO@PS exhibit higher biotoxicity than individual graphene oxide and polystyrene primarily through oxidative stress in zebrafish embryos emphasizing the environmental and health risks.

Scientists found that when tiny plastic particles (microplastics) combine with a carbon-based material called graphene oxide, they become much more toxic to immune cells than either substance alone. The combination caused more cell damage and death by harming the cells' energy centers and triggering harmful chemical reactions. This research suggests that microplastics in our environment could become even more dangerous when they mix with other materials, which is important for understanding health risks as plastic pollution continues to increase.

AI summary Read the abstract
Researchers examined how fluorescent nanoplastics modify the toxic effects of graphene oxide nanoparticles on freshwater algae. They found that the combination of nanoplastics and graphene oxide significantly amplified toxicity compared to either pollutant alone, increasing oxidative stress, membrane damage, and loss of photosynthetic activity. The study highlights that co-occurring nanoscale pollutants in freshwater environments may pose greater ecological risks than individual contaminants.

AI summary Read the abstract
This review examined how micro- and nanoplastics cause oxidative stress — a form of cellular damage — in living organisms, particularly when combined with other chemical pollutants in the environment. Co-exposure to microplastics and chemicals like pesticides or heavy metals tends to be more damaging than either pollutant alone.
