Bright-field images of rice plants showing C₇₀ uptake. (A) Bright field images of root and leaf portions of 1-week-old rice seedlings. Control plants without any C₇₀ (a–d) and treated plants showing C₇₀ uptake (e and f). Arrows indicate the aggregation of nanoparticles in corresponding C₇₀ treated plant tissues (scale bars are 20 μm). (B) (a) Bright field image of the leaf portion of a second generation rice plant. C₇₀ aggregates were mostly found near the leaf vascular system. (b) TEM image of the leaf cells showing C₇₀ particles (C₇₀: 20 mg/L). (c) transmission electron microscopy (TEM) image of C₇₀ particles with higher magnification. Reprinted from: Husen and Siddiqi (2014), Copyright © 2014 Husen and Siddiqi; licensee BioMed Central Ltd.
