Introduction

Nanotechnology is the science of manipulating matter on an atomic and molecular scale. Over the past decade, this eld has seen enormous growth in terms of precisely manipulating matter at the “nano” scale. At scales on the order of hundreds of nanometers, novel materials properties emerge, enabling the development of new classes of materials. The unique properties experienced at that scale have been utilized to create many new materials with a vast range of applications, such as in electronics, energy production, and, very recently, human health. It can create opportunities for paradigm shifting results, creating preventive, diagnostic, and therapeutic approaches to human diseases such as cancer, neurological, and cardiovascular [1-7] diseases. The strategy for uniting diagnostics and/or therapeutics on the nanoscale is dened popularly as nanomedicine, which offers benets due to the high degree of equivalent transport and distribution of the active agents within the biological systems for the diagnosis and treatment of diseases.
