Nanoparticles have major applications in biomedical, electronic and other fields. A broad overview of nanoparticle materials has been presented in this book. 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 discusses the inherent properties of nanoparticles and their applications in various fields. It includes a number of well researched studies which will help students and experts interested in the field of nanotechnology.
