Summary

Neutron scattering experiments revealed that polystyrene nanoplastics structurally disrupt phospholipid biomembranes at the molecular level, providing mechanistic evidence for how nanoplastics compromise cellular integrity. These molecular-scale insights help explain observed toxicity of nanoplastics in biological systems and highlight risks from environmental nanoplastic exposure.
