A facile synthesis of implantation of silver nanoparticles on oxygen-functionalized multi-walled carbon nanotubes: structural and antibacterial activity

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. Graphic abstract
