General description

Single walled nanotubes were prepared by the electric arc discharge method. The SWNTs were functionalized by purifying them in nitric acid. The carboxylic acid (-COOH) functionality along the length of the nanotube can be derivatized with a variety of functional groups. The average diameter of the nanotubes is 1.4nm ± 0.1nm. Transport properties of the SWNTs in soil was studied.

Application

Carboxylated SWNTs were used to modify an indium tin oxide (ITO) electrode towards the fabrication of a novel electrochemical immunosensor. Carboxylated SWNTs was further multifunctionalized and were used in studying the influence of attached chemical group on the sorption of pyrene conjugates of oligonucleotides. An electrochemical DNA biosensor was reportedly designed using functionalized SWNTs. It was used in the preparation of the chlorocarbonyl-functionalized SWNT. It was used to fabricate SWNTs/(Pb, Zn)-phosphate glass composite structure for the dual use as light sensor and photocurrent converter. Interaction of carboxylated SWNT with Caco-2 was investigated in detail.

We report a further advance in the bulk purification of nitric acid-treated single-walled carbon nanotubes (SWNTs) by use of high-speed centrifugation. We have already shown that low-speed centrifugation is effective in removing amorphous carbon (AC). In these earlier experiments, the
