Green synthesis of silver nanoparticles using banana sap as a solvent, reducing agent and capping agent is reported in this work. Banana sap has also been used as a binder to incorporate silver nanoparticles into cotton fabric. UV-Visible spectroscopy was used to monitor the quantitative formation of silver nanoparticles. Silver nanoparticle coated fabric showed high antimicrobial activity against gram negative bacteria such asPseudomonas aureginosaandEscherichia coli, and gram positive bacteria such asBacillus subtilisandStaphylococcus aureus.KeywordsGreen synthesis, Silver nanoparticles, banana sap, antimicrobial activity

Background and Objective: In this study, dudoa (Hydnocarpus alcalae C.DC.) leaf extract was used as a reducing and stabilizing agent in a novel one-step green synthesis of silver nanoparticles. Dudoa is an endemic plant in the province of Legazpi, Philippines and its seed oil was used as an anti-leprotic drug. Method: Therefore, the dudoa leaf extract was used to synthesize silver nanoparticles. Moreover, optimization of various parameters greatly affected the size and morphology of the synthesized AgNPs as indicated by the Ultraviolet-visible (UV-vis) spectrophotometry. The synthesized AgNPs were further characterized using spectral analyses such as XRD, EDX, SEM, FT-IR, TGA and DLS. The antimicrobial activity of synthesized AgNPs was also demonstrated. Results and Discussions: The synthesized AgNPs exhibited a diffraction pattern and a particle size ranging from 22-48 nm. The AgNPs also showed complete inhibitory and mild reactivity against representative pathogenic gram-positive (S.aureus) and gram-negative (E.coli) bacteria. Conclusion: Silver nanoparticles were successfully synthesized using H. alcalae leaf extract. Furthermore, this green synthesis approach appeared to be cost-effective, non-toxic, and eco-friendly which is a best alternative to the conventional chemical methods.
