Synthesis Methods of Metallic Nanoparticles - An Overview

Abstract

In this work, some of the synthesis methods of metallic nanoparticles are presented. There are two main ways to obtain nanoparticles, depending on the direction in which the processes take part, namely top-down (subtraction of material) and bottom-up (addition of material). Top-down methods include mechanical milling, while laser ablation and bioreduction are just a few techniques included in bottom-up approaches. The wide area of application of nanomaterials has led to the continuous development of the procedures used in their synthesis process.
