Determination of the structural features is a fundamental subject in nanotube research. A simple method is proposed to evaluate the structure of multiwalled carbon nanotubes (MWNTs) having either the concentric or the scrolled structure. Although transmission electron microscopy and Raman scattering did not indicate a distinct difference in the structural features of the MWNTs, the temperature dependence...
Deoxyribonucleic acid (DNA) molecules in water entangle together and form agglomerated spongy spherical structure. However, when the multiwall carbon nanotubes (MWNTs) are added to the solution, DNA effectively interacts with MWNTs and disentangled DNA molecules immobilize at the surface of MWNT. Such phenomena are identified by the tapping mode atomic force microscopy (AFM), which clearly indicates...
