Nanobrook Omni测量应用案例-14

The widespread application of copper oxide nanoparticles (nCuO) results in ecological risk when nanoparticles enter the environment. This study clarifies the mechanism of nCuO toxicity in Arabidopsis thaliana seedlings via comparison with copper (Cu) ion bioeffects. Under the same culture conditions, Cu2+ ion exposure exerted a stronger inhibitory effect on plant fresh weight and growth and caused stronger oxidative disruption (measured by malondialdehyde, MDA) than nCuO exposure. The Cu2+ ions also showed a stronger induction effect than did nCuO on the activity of antioxidant enzymes and the transcription of antioxidant-related genes.
