Synthesis of Silver Nanoparticles using Fagonia Cretica and their Antimicrobial Activities

Abstract

Silver nanoparticles (NPs) were synthesized using an efficient bioreducing agent from Fagonia cretica extract having advantages of eco-friendliness over chemical and physical methods. Sharp color change and appearance of representative absorption peak in UV-visible spectra confirm the quick reduction of Ag salt and evolution of Ag NPs. Morphological and structural aspects showed that resulted Ag NPs are well-crystalline with an average size of 16 nm. Further, compositional analysis of extract confirmed the existence of active bioreducing and stabilizing agents in Fagonia cretica extract. Furthermore, various concentrations of AgNO3 and Fagonia cretica extract were employed to obtain higher yield with better stability of Ag NPs. The resulted Ag NPs showed effective antibacterial activity against Proteus vulgaris, Escherichia coli, Klebsiella pneumoniae. It is found that the Ag NPs induce maximum reactive oxygen species (ROS) in Proteus vulgaris as compared Escherichia coli and Klebsiella pneumoniae to induced cell toxicity, while ROS production in presence of Ag NPs was 30% higher than only plant extract and control in all three bacterial strains. Thus, present finding show that plant extracts can be a useful natural resource to prepare functional nanomaterials for targeted applications especially in the field of biotechnology.
