Development innovation of silver nanoparticles used leaves of banana (Musa sapientum) as eco-friendly bioreductor

Background: Silver nanoparticle could be developed by natural reducing agent like Epigallocatechin Gallate (EGCG) of banana leaves (Musa sapientum) as bioreductor in biosynthesis. Objective: This study aimed to examine the formulation and characterization of silver nanoparticles using the combination of banana leaf (M. sapientum) extract containing epigallocatechin gallate (EGCG) for biosynthesis. The biosynthesis of silver nanoparticles is eco-friendly and low energy process. Method: Each formula was added with 500microlitre AgNO3. Identification of nanoparticles was characterized by duration of its discoloration, its absorbance using UV/Vis spectrophotometer and FTIR, its particle size using PSA, and its morphology under TEM. Result: The silver nanoparticle formation need less than 15 minutes. The measurement of its absorbance showed the wavelength of this silver nanoparticles are in the range of 410-480nm. Characterization using FTIR showed a decrease in absorption of the functional -OH group spectrum. This particle has the smallest particle size in value of 57.16 ± 0.40 nm in spherical shape. Conclusion: Nanosilver could be prepared using banana leaf extract using low energy biosynthesis process. Keywords: characterization, nanosilver, banana leaf (M. sapientum)
