Nanohybrids formed by the multiwalled carbon nanotubes (MWCNTs) and metallic nanoparticles (NPs) have gained immense interest recently for their potential biological applications. In this paper, we present a comprehensive study of the nanohybrid formed with varied concentrations of Au-NPs with MWCNTs. It is demonstrated that the concentration of Au-NPs in the nanohybrid is crucial in defining ultimate characteristics of the nanohybrid. The MWCNTs were functionalized with varied concentrations of Au-NPs (40–100 nano Molar (nM)) and characterized extensively by the X-ray diffraction, electron microscopy, Raman spectroscopy and UV–Vis absorption spectroscopy. The process of purification and acid treatment led to the activation of –COOH bond at the surface of MWCNTs and functionalization with Au-NPs also induced stresses as observed in the X-ray diffraction patterns. The fusion of Au-NPs in the …
