Green Synthesis of Silver Nanoparticles Using Walnut Shell Powder and Cynara sp. and their Antibacterial Activities

The silver (Ag) is a well-known material with interesting properties (i.e. catalytic activity, antimicrobial, etc.). nano-sized particles of propose enhanced due to having relatively higher surface areas. green synthesis promising way preparation/production being more environmentally friendly by utilization less harmful materials. In this work, the plant extracts (Cynara & Walnut shell powder) were used as reaction media for nanoparticles (Ag NPs). produced via two ~46 nm and ~109 in size, respectively. antibacterial activities (against E. coli S. aureus species) determined minimum effective concentrations (MIC) activity investigated.
