This book focuses on the green synthesis of silver nanoparticles (AgNPs) using plant extracts from Capparis spinosa (caper plant) and Allophylus serratus, emphasizing their eco-friendly, cost-effective, and non-toxic approach compared to traditional chemical methods. AgNPs exhibited strong antibacterial activity against Gram-positive (Staphylococcus aureus, Bacillus subtilis) and Gram-negative (Escherichia coli, Pseudomonas aeruginosa) pathogens Plant-mediated synthesis avoids toxic byproducts and aligns with green chemistry principles.Nanoparticles showed stability, high surface-area-to-volume ratios, and biocompatibility.The book underscores the potential of plant-derived AgNPs as sustainable alternatives for combating microbial resistance and advancing nanomedicine. Experimental validation and scalability for industrial applications are recommended for future work.
