UTILIZING BANANA PEEL WASTE EXTRACT FOR GREEN SYNTHESIS OF SILVER NANOPARTICLES AND THEIR ANTIBACTERIAL APPLICATION

Silver nanoparticles (AgNPs) were successfully produced through a green synthesis method involving the utilization of waste banana peel waste (BPW) extract. BPW has attracted considerable attention for its attributes as a straightforward, environmentally friendly, and non-toxic material. To facilitate this process, BPW powder was created by boiling, blending, and air-drying, serving as both a reducing and capping agent. The biosynthesized AgNPs underwent characterization via UV-visible spectroscopy, Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), and Field Emission scanning electron microscopy (FE-SEM). Furthermore, antibacterial activity tests were conducted on cotton fabrics to optimize the process and assess its effectiveness. The results revealed a distinct absorption peak at 420 nm corresponding to AgNPs, a finding corroborated by FE-SEM and energy dispersive spectrometry (EDS). The application of AgNPs from BPW on fabrics exhibited outstanding antibacterial activity by inhibiting the growth of Staphylococcus aureus and Escherichia coli. Overall, the present findings support the use of BPW extraction as a cost-effective, environmentally friendly, and efficient approach for the green synthesis of AgNPs with promising antibacterial properties on fabrics.
