652490 is carboxylic acid functionalized single-walled carbon nanotubes which are ready to use. Another carboxylated CNTs (P/N# 755125) are carboxylic acid functionalized multi-walled carbon nanotubes. Generally speaking, single-walled carbon nanotubes can provide a higher electrical conductivity than multi-walled carbon nanotubes.

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.[1] The average diameter of the nanotubes is 1.4nm ± 0.1nm. Transport properties of the SWNTs in soil was studied.[2]
Application
Carboxylated SWNTs were used to modify an indium tin oxide (ITO) electrode towards the fabrication of a novel electrochemical immunosensor.[3] Carboxylated SWNTs was further multifunctionalized and were used in studying the influence of attached chemical group on the sorption of pyrene conjugates of oligonucleotides.[4] An electrochemical DNA biosensor was reportedly designed using functionalized SWNTs.[5] It was used in the preparation of the chlorocarbonyl-functionalized SWNT. [6] It was used to fabricate SWNTs/(Pb, Zn)-phosphate glass composite structure for the dual use as light sensor and photocurrent converter.[7] Interaction of carboxylated SWNT with Caco-2 was investigated in detail.[8]
