This paper is about the carbon nanotube(CNT) samples called as CNT cartridges. The CNT cartridges are useful to make it better to fabricate the nano-sized devices like nanoprobes and nanotweezers through physical attachment. To make these cartridges, we need to align CNTs and to purify them from raw material. There is a variety of methods to align 1-dimensional nanostructures like nanotubes and nanowires. In this review, we mainly focused on the methods using electric field. And we will introduce various researches in relation to the CNT cartridges and the fabrication methods using the CNT cartridges and nanomanipulation techniques.
