The vegetable kingdom, with approximately 300,000 species of plants available onthe planet, is an abundant source of phytomolecules with reducing and stabilizingproperties suitable for the production of metal nanoparticles by eco-friendly and economicalsynthetic routes. This is the case for silver nanoparticles (AgNPs) synthesizedusing plant leaf extracts, which has become a developing research field dueto optical, electrical, magnetic, catalytic, bio(medical), and antimicrobial applicationsof the resulting nanocomposites.The goal of this chapter is to bring to the readers a general outlook and the currentstate of the art of the green synthesis of AgNPs using leaf extracts with different typesof phytochemicals, considering experimental conditions to control the final size,shape, and homogeneity of the AgNPs. The current interest in the leaf extractmediatedsynthesis of AgNPs is not only promoted by the optical, electrical, magnetic,and antimicrobial intrinsic properties of the metal nanoparticle, but also bythe synergic benefits of the incorporation of suitable phytochemicals that allowthe assembly of new green nanocomposites for utilization in electronic components,cryogenic superconducting materials, (bio)sensor materials, cosmetic products, andantimicrobial composites, among others (Abbasi et al., 2014; Burda et al., 2005;Chung et al., 2016; Jain et al., 2008; Mahmoudi et al., 2020; Ni and Wang, 2016;Siddiqi et al., 2018; Trotta and Mele, 2019; Wei et al., 2015).In this chapter, we have revised and discussed recent literature describing the useof harvested plant leaves as a source of phytochemicals for green synthesis of silvernanoparticles (AgNPs) and describe synthetic methods, characteristics, properties,and applications of the green-prepared nanocomposites. Finally, it is noteworthy to mention that the use of leaf extracts as a naturally occurring media for the preparationof metal nanoparticles is a growing field with a large potential for multipleapplications.
