Chapter 1 - Hybrid Nanoparticles: An Introduction

Abstract

This chapter aims to introduce the hybrid nanoparticles, which are constructed from at least two different nanoparticles, in order to overcome the limits of single-component nanoparticles, to improve properties, to achieve new properties not possible for single nanoparticles, and/or to achieve multiple functionalities for single nanoparticles. Diverse hybrid nanostructures, such as core–shell, yolk–shell, heterodimer, Janus, dot-in-nanotube, dot-on-nanorod, nanobranches, etc., have been mentioned. The rational design, controlled synthesis, and in depth understanding of structure–property relationships are all highly important in pushing forward their promising applications.
