Definition

Nanoparticles are spherical-like particles with their diameter in the range of 1 and 100 nm. Metal nanoparticles are nanoparticles composed of metal elements, which are usually covered by organic molecules as a protective layer. Polymers, surfactants, and metal ligands can be used as protective molecules.

Introduction

During the past few decades, research on metal nanoparticles, clusters, and colloids has been extensively pursued because of the specific properties that are controlled by the size of these materials [1, 2].

Figure 1 shows examples of the symmetrical structure of face-centered cubic (fcc) nanoparticles in several sizes. An M13 nanoparticle has one atom in its core, which is surrounded by 12 shell atoms. An M55nanoparticle has 13 atoms in its core which is surrounded by 42 shell atoms. These particles contain more surface atoms than atoms located in their cores. Therefore, these nanoparticles...
