DNA cleavage and chemical transformation of nano-plastics mediated by surface ligand and size

Abstract

Here, we investigated the photochemistry of nano-plastic particles with different surface ligands and sizes (i.e. PS-NH₂ 40, 80, 100, 200 nm and PS-COOH 40, 80, 100, 200 nm) under a solar simulator. Our findings provide new insights into DNA cleavage and chemical transformation of nano-plastics, especially mediated by different ligands and sizes.
