In this study, we investigate the antibacterial properties of green synthesized silver nanoparticle decorated on functionalized multi-walled carbon nanotube (MWCNT). Silver nanoparticles (AgNPs) were synthesized using a microwave irradiation technique with Hyptis capitata leaf extract. The nanocomposite was prepared by incorporating carboxylic acid functionalized MWCNTs with AgNPs, employing a simple method that utilized green strategies. The synthesized nanocomposite was characterized using various techniques including Fourier-transform infrared spectroscopy, UV–Vis spectroscopy, high-resolution transmission electron microscopy, X-ray diffraction, thermogravimetric analysis, and Raman spectroscopy. These analyses confirmed the successful synthesis of the nanocomposite and provided insights into its structural and morphological properties. The antibacterial potential of the nanocomposite was evaluated against two common bacterial strains, Staphylococcus aureus and Escherichia coli. The results demonstrated that the nanocomposite exhibited has superior antibacterial activity against both strains compared to the AgNPs. This enhanced antibacterial property suggests a synergistic effect resulting from the combination of AgNPs and MWCNTs in the nanocomposite. This research highlights the successful synthesis of silver nanoparticles decorated on functionalized multi-walled carbon nanotube through a green and straightforward approach. The nanocomposite displayed excellent antibacterial activity against S. aureus and E. coli, making it a promising candidate for applications in antibacterial materials and biomedical devices.
