Abstract Silver nanoparticles imply as a promising competitor for enhancement of future antibacterial treatments due to its wide range of activity. The present study reports the implantation of Oxygen-functionalized Multi-Walled Carbon Nanotubes (O-MWCNTs) onto Silver nanoparticles in their pure phase are warily and homogenously implanted via facile approach by means of silver nitrate as precursor material. X-ray Diffraction was performed to detect crystalline size; differentiation of bands for P-MWCNTs, O-MWCNTs and Ag-MWCNTs was detected by Fourier Transform Infrared Spectroscopy; the exact shift was clearly depicted using Raman Spectroscopy; weight loss percentage through Thermogravimetric Analysis; potential values by Zeta Potential; Size, morphology and elemental analysis using Transmission Electron Microscopy and FE-SEM with EDX respectively. The antibacterial studies of Ag-MWCNTs were performed for four bacterial strains i.e., Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa through disc diffusion method. As the concentration of Ag-MWCNTs was high, the zone of inhibition is high especially in Gram+ve bacteria signifying as a good anti-bacterial agent.

1 Introduction Multi walled carbon nanotubes (MWCNTs) comprise an encouraging application in almost all aspects of Nanotechnology [1]. In contrast to other material forms of carbon–diamond and graphite, carbon nanotubes (CNTs) are one dimensional and support to function specifically in preparing metal, metal oxide CNT composites [2, 3]. In recent times, silver nanoparticles decorated on MWCNTs as composite material has attracted significant interest with abundant array of latent applications in the field of solar power alteration and photo catalysis [4, 5]. It is well known that the binding of metal nanoparticles on to the surface Vol:.(1234567890)
of CNTs (CNTs-Metals) is very poor [6]. It has been reported [7] by the inclusion of defects and functional groups on CNTs, the surface reactivity can be increased. Therefore, functional grou
