Nannotechnolgy significantly impacting the humanlife and every dimensions of science. The field of medicine and drug delivery succesfuly used nanoscience for various applications. This books explores the simple method of preparation of nanoparticles without the use of higly sophisticated instruments and expensive procedures.This book also guides the beginners about basic charecterization techniques of nanoparticles and evaluations such as XRD,Zeta sizer , Zeta potential and in vitro studies. The procedures, experiments and results are discussed in brief and straigh which is easy to undersatand and useful for the initial level researcher who is eager do some thing on nanomedicine or nanodrug delivery. Cancer is the challenging disease the research on cancer completely shifted to nanotechnology due to the promising results. This research work also used the 5 Fluro Uracil for colon cancer as model drug. Simply this book is nanoparticle treatise for learners.
