The toxicity of nanoparticles to freshwater microalgae is significant importance in maintaining the overall stability aquatic ecosystems. However, transport mechanism and response towards nanoplastics (NPs) remain be further investigated. In this study, we examined internalization mechanisms polystyrene (PS-NPs) microalga Chlorella sorokiniana. results revealed that PS-NPs inhibited algal cells' growth disrupted cell integrity upon contact, leading shrinkage or rupture. Moreover, amino-modified (Nano-PS-NH2) exhibited greater C. sorokiniana than carboxyl-modified (Nano-PS-COOH). Furthermore, inhibition was observed when four different endocytosis-related inhibitors were used, indicating internalized can enter cells through endocytic pathways. More importantly, exposed Nano-PS-NH2 responded reduction carbon sources energy resulting from suppression photosynthesis by regulating metabolism carbohydrates. These findings elucidate effects on sorokiniana, including their impact morphology metabolism, while shedding light NPs which deepen our understanding algae provide important theoretical support for solving such ecological environment problems.
