The College of Education for Pure Sciences, Department of Life Sciences, has conducted a doctoral thesis on "Evaluation of the Bioactivity of Silver Nanoparticles Synthesized from Aqueous Extracts of Some Plant Species Against Antibiotic-Resistant Bacteria Associated with Burn Injuries." The thesis, presented by researcher Alaa Mohammed Rasha Abdul Amir, included this study to isolate and identify bacterial species in burn patients and determine their drug sensitivity. It also explored the effectiveness of biosynthesized silver nanoparticles as potential antimicrobials against pathogenic bacteria and evaluated their toxicity to normal and cancer cells, along with their antioxidant properties. The research included collecting clinical samples from burn patients and identifying pathogenic bacteria associated with these injuries. A worrying pattern of resistance was revealed. Green manufacturing was adopted to prepare the silver nanoparticles. The synthesized nanoparticles demonstrated clear antibacterial activity against resistant bacteria and demonstrated a significant inhibitory capacity. Cytotoxicity tests revealed that the particles had a selective effect, being less toxic to normal cells than to cancer cells. The particles also proved effective as antioxidants. These results indicate that nanoparticles manufactured from plant extracts represent a promising option for inhibiting multiresistant bacteria. This study also reinforces the trend toward the use of biosynthesized compounds in medical fields
