This book aims to prove helpful for all researching in the field of nanoparticles. Nanoparticles have made a significant impact in the scientific domain in the past few years. The properties of numerous conventional materials changed when shaped from nanoparticles. Nanoparticles have a larger surface area per weight as compared to larger molecules which makes it more reactive and effective than other molecules. This book covers various aspects related to metallic nanoparticles and their testing technology. It includes a number of well researched studies which will help students and experts interested in the field of nanotechnology.
