Abstract

Background: The feasibility of plant extracts for metallic nanoparticle fabrication has been demonstrated. Each plant species impacts differently on formed nanoparticles, thus specific plants need to be explored in detail. Objective: Continuing the fabrication of nanoparticles using green method, Garcinia mangostana shell and Tradescantia spathacea leaf extract are exploited as reducing sources to form two types of silver nanoparticles (GMS-AgNPs and TSL-AgNPs) less than 50 nm. Methods: Structural characterization of GMS-AgNPs and TSL-AgNPs was performed by ultravioletvisible spectrophotometry (UV-vis), Fourier transform infrared spectroscopy (FTIR), X-ray energy dispersive spectrometer (EDAX), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Antifungal tests of GMS-AgNPs and TSL-AgNPs were performed with Aspergillus niger, Aspergillus flavus, and Fusarium oxysporum. Results: UV-vis spectra with the 440-nm peak demonstrate the silver nanoparticle formation. FTIR analysis shows the GMS-AgNPs and TSL-AgNPs modified by organic functional groups. The SEM and TEM images indicate that the GMS-AgNPs are spherical shaped with rough edged, while the TSL-AgNPs are spherical shape with smooth surface. The GMS-AgNP average size (15.8 nm) is smaller than TSL-AgNP (22.4 nm). In addition, antifungal tests using Aspergillus niger, Aspergillus flavus, and Fusarium oxysporum reveal that GMS-AgNPs and TSL-AgNPs can significantly inhibit the proliferation of these fungal strains. Conclusion: Garcinia mangostana shell and Tradescantia spathacea leaf extract as renewable and eco-friendly resources playing a dual role for nanoparticle biosynthesis create GMS-AgNPs and TSL-AgNPs with high antifungal efficiency for biomedical or agricultural applications.
