Nanotechnology as an Emerging Field in the Arena of Medicine

Abstract

Nanotechnology as an emerging scientific field has enabled humanity to manipulate the environment at molecular and atomic level and has touched and even revolutionized all scientific fields due to its characteristic features. Medicine is one of the important fields that witnessed a nanotechnological revolution that guided medical scientists to device new approaches to study pathologies and explore genuine therapeutic tricks by exploring nanotechnology to operate on more specific molecular targets and to reduce the adverse risks and side effects imposed by the conventional approaches. By manipulating drugs and other materials, the fundamental properties and bioactivity of the materials can be altered at the nano scale. These tools can led to the different characteristics of drugs or agents such as a) modulation in solubility and blood pool retention time, b) controlled release over short or long durations, c) environmentally triggered controlled release or highly specific site-targeted deliver.
