Abstract

Ion irradiation and the inevitable damage it creates has long been a topic of great interest in the field of medicine. Irradiation of MWNTs with diameters of about 10 nm by 3 keV Ar ions followed by X-ray photoelectron spectroscopy and TEM probing demonstrated that the bombardment resulted in the appearance of carbon dangling bonds, which can be understood in terms of single and multi atom vacancies[2]. A gradual amorphization of the carbon network was reported, and for maximum irradiation doses used (more than 1019 ions/cm2 ) MWNTs with originally hollow cores transformed to nano-rods composed of amorphous carbon, but the irradiation did not change the sp2 hybridization of carbon to sp3 hybridization. In particular, the effect of selecting a particular ion during irradiation, determines the mobility of the material. The critical bottlenecks in drug discovery may be overcome by using arrays of CNT sensors [3] and current information technology solutions for identification of genes and genetic materials for drug discovery and development. This investigation will be carried out to study the effect of swift heavy ion irradiation on the surface morphology of f-MWCNTs..
