Title: Nanomaterials; Carbon nanotubes; Self-assembly using bile acids
Description: Single wall carbon nanotubes enclosed in bile acid shells self assembled into a sheaf of long ordered fibrils each composed of several nanotube rods. Treating the microscope slide with a hydrophobic compound causes the fibrils to cluster like this at specific sites, probably at defects in the hydrophobic surface. Image, 70 micrometers wide, was taken using near-infrared fluorescent microscopy. (Color added for clarity.)
