Abstract

In this investigation, for the first time, we used Fragaria ananassa (strawberry) leaf extract as a source of natural reducing, capping or stabilizing agents to develop an eco-friendly, cost-effective and safe process for the biosynthesis of metal-based nanoparticles including silver, copper, iron, zinc and magnesium oxide. Calcinated and non-calcinated zinc oxide nanoparticles also synthesized during a method different from our previous study. To confirm the successful formation of nanoparticles, different characterization techniques applied. UV-Vis spectroscopy, X-ray Diffraction (XRD) spectroscopy, Field Emission Scanning Electron Microscopy (FESEM) coupled with Energy Dispersive X-ray Spectroscopy (EDS), Photon Cross-Correlation Spectroscopy (PCCS) and Fourier Transformed Infrared Spectroscopy (FT-IR) were used to study the unique structure and properties of biosynthesized nanoparticles. The results show the successful formation of metal-based particles in the range of nanometer, confirmed by different characterization techniques. Finally, the presented approach has been demonstrated to be effective in the biosynthesis of metal and metal oxide nanoparticles.

Summary

Introduction

Metal-based nanoparticles (NPs) are used in many fields including agriculture, medicine, cosmetics, water treatment, electronics and catalysis, as their huge potential in nanotechnology is due to their ideal electrical, optical, magnetic and chemical properties [1,2]. Synthesis of metal-based NPs mainly mediates by physical or chemical methods. Supportive researches on plant-mediated biosynthesized nanoparticles indicate that biogenic nanomaterials are biocompatible and an effective therapeutic agent against bacterial, fungal infections, and cancer treatment [3]. The application of such NPs as nano-biopesticide and nano-fertilizer is more acceptable as they are benign for plants and cause less environmental contamination in comparison to conventional chemicals, as toxic chemicals may remain in the synthesized NPs and limit their application due to the toxicity of harmful residues, especially in the field of medicine, food industry and agriculture. To mitigate the problem of expensive equipment and toxic chemicals, green methods have been developed rapidly, presenting facile synthesis approaches [4,5,6]
