ABSTRACT
Metallicnanoparticles have been traditionally synthesized using wet chemical techniques,where the chemicals used are quite often toxic and flammable. In this research,we present a simple and ecofriendly biosynthesis of Ag nanoparticles using Ulvafasciata crude ethyl acetate extract as reducing and capping agent. The bionanoparticlecharacterized with UV-vis Spectroscopy, FTIR, XRD, SEM and EDX. Characterizationreveals that the nanoparticles are crystalline in nature, spherical in shapeand poly-dispersed with size ranging from 28 to 41 nm. The alkyne group(3424.30 cm-1) of U.fasciata crude ethyl acetate extract shifted and reduced the AgNO3. GC-MS analysisrevealed the presence of 1-(Hydroxymethyl)–2, 5, 5, 8A-tetramethyl decahydro-2-napthalenol as reducing agent and hexadecanoic acid was found to be astabilizing agent. Ulva fasciata based bionanoparticles inhibited thegrowth of Xanthomonas campestris pv. malvacearum (14.00±0.58 mmZone of inhibition), with a Minimum Inhibitory Concentration of 40.00±5.77μg/mL.The study shows that U. fasciata crude ethyl acetate extract could beused as a reducing agent for simple ecofriendly synthesis of silver nanoparticles.However, more studies are essential before recommending them for diseasemanagement.
