Figure 2

(a,c) Bright field modes. The red arrow in panel a shows a broken CNT falling on the substrate. Scale bar, 100 μm (in a); 20 μm (in c). (b) Dark field mode. Scale bar, 100 μm. (d,e) Optical images with low magnification (× 50). Scale bar, 1 mm. The light source in panel d is green laser, whereas the light source in panel e is visible light. (f) High-resolution optical image of a suspended CNT decorated with TiO2 NPs. The small TiO2 NPs indicated by the red arrows have diameters <200 nm. Scale bar, 1 μm.
