Preparation and characterization of MWCNT dispersed in various solutions

In modern technology of biomedical applications, the potential of carbon nanotubes based materials has been widely used in recent years. In this paper, the preparation of the multi wall carbon nanotube (MWCNT) with biocompatibility of these composite are investigated, although many aspects have been studied separately by researchers. We have chosen three different solvents; namely chitosan, Sodium Dodecyl Sulfate (SDS), and isopropyl alcohol (IPA) to mix with MWCNT respectively. This functionalized CNT with carboxylic (COOH) groups were prepared in three different liquid forms and further will be dropped on fabricated Interdigitated electrodes (IDEs) as devices. Scanning electron microscopy (SEM) was used to identify the structures effect of synthesized MWCNT in different solvents. The conductivities show the ability of chitosan and SDS to be used as a solvent in order to synthesis MWCNTs and further will be used as a biosensor.
