Nanotechnology is one of the most widely used sciences in the world, which plays an essential role in many medical, research and laboratory fields. Researchers need to carry out extensive research to obtain accurate results from this science. As a biochemical researcher and researcher, I also knew from my duties that I would carry out investigation on both the cell and the animal sector in order to provide these results in the right way to other researchers. I am very pleased that there was an opportunity to put part of my research into a regular collection. The book consists of 9 chapters, in which synthesis of zinc oxide nanoparticles in green and some biochemical properties including antioxidant, cytotoxic and anticancer properties of these nanoparticles are investigated. I hope that this book will be of interest to the readers of science. I am grateful to all the people who helped me in this book. Hoping for an empty sack of Sickness for all Beings Along with world peace.
