ANTIHELMINTHIC, ANTICANCER, ANTIOXIDANT ACTIVITY OF SILVER NANOPARTICLES ISOLATED FROM F.oxysporum

Human beings are often infected by microorganisms such as bacteria, molds, yeasts, and viruses present in their living environments. Because of the emergence and increase in the number of multiple antibiotic-resistant microorganisms and the continuing emphasis on health-care costs, many scientists have researched methods to develop new effective antimicrobial agents that overcome the resistances of these microorganisms and are also costeffective. Such problems and needs have led to resurgence in the use of silver-based antiseptics that may be linked to a broadspectrum activity and considerably lower propensity to induce microbial resistance compared with those of antibiotics. In particular, silver ions have long been known to exert strong inhibitory and bactericidal effects as well as to possess a broad spectrum of antimicrobial activities. Silver ions cause the release of K+ ions from bacteria; thus, the bacterial plasma or cytoplasmic membrane, which is associated with many important enzymes and DNA, is an important target site of silver (Abhilash et al., 2011) .
