Summary of some green approaches to fabricate and evaluate the antibacterial ability of Ag NPs nanoparticles

Abstract

Some green methods for the preparation of silver nanoparticles (Ag NPs) from plant extracts are listed in this review. Plant extracts (guava leaves, aloe vera leaves, Jatropha seeds (J. curcas) or honeybee wings,...) are used in the fabrication of Ag NPs as a reducing agent for Ag⁺ (from silver nitrate salt) to Ag and to stabilize the nanoparticles during the development process. Simple wet chemical method from organic bases such as triethyl amine, pyridine, glucose to fabricate stable and pollution-free Ag NPs nanoparticles is also one of the green approaches to fabricate Ag NPs nanoparticles. Methods for measuring material properties are discussed such as UV-vis, XRD, SEM, antibacterial and antifungal properties. The fabricated Ag NPs nanoparticles have a nanometer particle size of 10-70 nm, have a spherical particle shape and have very good antibacterial and antifungal properties, promising to exploit the application field of AgNPs in agriculture to control pathogens, various pharmaceutical and biomedical applications. This statistic is to expand and deepen further studies on Ag NPs nanomaterials with many interesting useful applications.
