摘要： Green chemistry is a branch of chemistry that deals with natural materials such as plants, fungi, bacteria, algae, and rocks rather than chemical components. Advantages of green chemistry rather than chemical are that no toxic components are released, inexpensive, available anytime, easy to get, and eco-friendly. Metallic nanoparticles have received great attention from chemists, physicists, biologists and engineers who wish to use them for the development of a new generation of nanodevices. One of the important metal nanoparticles is the silver nanoparticles (AgNPs). Silver is a nontoxic agent having an antibacterial, antifungal, and antioxidant properties. AgNPs have been used in many applications such as catalysis, biotechnology, biomedical applications, electronics, and in the treatment of burns and wounds. The green synthesis of AgNPs involves three main steps: the selection of the solvent medium, the selection of environmentally reducing agents, and the selection of non-toxic substances for the stability of AgNPs. In this review, we will discuss some green chemistry methods to synthesize AgNPs via plant extracts and other natural agents, such as fungi, bacteria, and algae. In addition, we will compare between these methods, according to their applications and stabilities.
