Abstract
Since the ability of bacteria to acquire resistance is increasing, it is important to find alternative therapeutics. One possible way to deal with this problem is the use of nanoparticles as possible alternatives to antibiotic therapy. Silver nanoparticles (AgNPs) are viewed as a novel type of antibacterial agents. AgNPs can be synthesized using raw materials, such as red sand that found in nature. Characterization of the AgNPs was achieved using variety spectroscopic and microscopic devises. AgNPs showed antibacterial activity and large effect when combined with different antibiotics against Staphylococcus aureus, Acinetobacter baumannii, Escherichia coli, Salmonella typhimurium, Pseudomonas aeruginosa and Proteus vulgaris.
