Effects of BSA-SeNPs on mitochondrial morphology. (A) Transmission electron microscopy (TEM) images of hippocampal neuronal cells treated with Hemin (6 h), BSA-SeNPs + Hemin (6 h), BSA-SeNPs (6 h). Shrunken mitochondria were marked as single white arrowheads (upper scale bar: 2 μm, bottom scale bar: 500 nm). (B) Internalization of BSA-SeNPs into mitochondria of hippocampal neurons was imaged by confocal microscopy (scale bar: 16 μm). The nucleus of hippocampal neuron was stained with Hoechst (blue); mitochondria were stained with Mitotracker Red (red).
