Figure 12From: Uptake, transport, distribution and Bio-effects of SiO2 nanoparticles in Bt-transgenic cotton TEM images of root sections of non-transgenic cotton (A-B) and Bt-transgenic cotton (C-D) after 21 days treated with SiO2 NPs. A and C were TEM images of nontransgenic and Bt-transgenic cotton roots without SiO2 NPs treatments. B and D were TEM images of non-transgenic and Bt-transgenic cotton roots treated with 2000 mg.L−1 SiO2 NPs.Back to article page
