Fig. 2From: ROS/mtROS promotes TNTs formation via the PI3K/AKT/mTOR pathway to protect against mitochondrial damages in glial cells induced by engineered nanomaterialsImages of TiO2NPs and MWCNTs captured by TEM and SEM. (a1, b1) TEM images show the size of 1 mg/mL TiO2NPs and MWCNTs in water. Scale bar = 100 nm. (a2, b2) SEM images demonstrate the morphology of 1 mg/mL TiO2NPs and MWCNTs in water. Scale bar = 500 nmBack to article page
