Nanoplastics are potentially more dangerous than microplastics

Nanoplastics are probably much more dangerous for living organisms than microplastics because they are more abundant and reactive. They can potentially reach more remote locations and penetrate in living cells. Here we compare nanoplastics with microplastics and engineered nanoparticles, with focus on formation, size, reactivity, mobility, biofilms, and interactions with microbes, pollutants and natural organic matter.
