Polystyrene nanoparticles induce DNA damage and apoptosis in HeLa cells.

Nanoplastics (NPs) are plastic particles, typically less than 100 nm in size, that result from daily life products as well as the degradation of larger plastic debris. Due to their small size and chemical composition, they can interact with biological systems in ways that larger plastic particles cannot. Humans are continuously exposed to NPs and several studies showed the potentially toxic effects of these latter on health.
