This paper deals with the bio-synthesis of silver nano-particles using a soil fungi. In this work, FTIR examinations indicated that the encountered soil particles actually contained Silver particles, while XRD analysis confirmed the silver was in the nano-crystalline phase. Moreover, the hurried decline of silver (Ag+) ions monitored using UV-visible spectrophotometer, demonstrated that these silver nano-particles formed within 19 minutes. In addition, transmission electron microscopy (TEM) revealed that the synthesized silver nano-particles come in a size ranging between 16-57 nm and have a variety of shapes, including round, rod and uneven. The present study thus concludes that silver nano-particles were actually produced and that these have admirable antibacterial activity. The current study also indicates that increasing concentration increases the rate of reduction and decreases the particle size.
