Figure 3From: Suspended hybrid films assembled from thiol-capped gold nanoparticlesTEM images. TiO2 nanotubes imbedded with MPA-DT-capped AuNPs: (a to d) thick-walled nanotubes; (e,f) thin-walled nanotubes; and (g,h) thin-walled nanotubes after being heated at 250°C for 30 min. The imbedded AuNPs can be seen with the guide of white arrows.Back to article page
