This review book describes biogenic and green synthesis of Copper nanoparticles with different methods. 80% of the world population using traditional medicinal plant as primary health care. Different plant posses different properties according to their use in disease. Synthesis mentioned in book is carried out using plant material by different methods. Biogenic Nanoparticles are those particles which are synthesized by biogenic systems like plants, microbes, fishes etc. This biological synthesis of metal nanoparticles is mainly a strategy which is employed to protect the system from the toxic and harsh effect. Conventional methods consist of some toxic chemicals which hazards environment that's why this book will show you selective method for biogenic synthesis of metal nanoparticles with non-toxic material (plants), cost effective and eco-friendly. Book explains properties of Copper metal nanoparticles and includes mechanism behind the reaction. This book provides the basic ideaof various syntheses so; it will be really helpful for the upcoming researchers who want to work on plant synthesis.
