A uncanny potential of plants for metal nanoparticles synthesis

Abstract

In this era, metal nanoparticles have captivated researchers because of their impending applications in numerous fields such as biomedical, catalysis, electronics etc.1–4 The properties of nanoparticles can be tuned by their size, synthesis process, reaction parameters, which make them the special candidate for every field. Generally, these nanoparticles are synthesized by two methods top down and bottom up. The top-down suggests the nanoparticles preparation by lithographic techniques, ball milling, etching, sputtering, etc. The most effective approach for the synthesis of nanoparticles is the bottom-up methods, in which nanoparticles are grown from simpler molecules and size or shape of nanoparticles can be controlled or modulated by changing the concentration of chemicals and reaction condition (temperature, pH etc.).5
