From: Graphene oxide amplifies the phytotoxicity of arsenic in wheat

Structural damage to the cell wall and plasma membrane.
Fourier transform infrared spectra (a) and electrolyte leakage (b) in root cells. GO10 and GO1 are cells exposed to 10 and 1 mg/L GO, respectively. As, arsenic (V) 10 mg/L; GO, graphene oxide. The chemical groups in the Fourier transform infrared spectra refer to previous work25,26,27.
