Abstract
The method of synthesizing antimicrobial silver nanoparticles using pigeon dung includes collecting pigeon dung and suspending the pigeon dung in water to produce a pigeon dung aqueous extract, filtering the pigeon dung aqueous extract, adding a solution including a silver source to the pigeon dung aqueous extract to produce a mixture, and resting the mixture to allow silver nanoparticles to form. In an embodiment the antimicrobial pigeon dung nanoparticles may be incorporated in a pharmaceutical composition.

1-2. (canceled)
A method of synthesizing pigeon dung nanoparticles, the method consisting of the sequential steps of:
- (a) collecting pigeon dung;
- (b) suspending 17 g of pigeon dung in 90 ml of water to form a pigeon dung aqueous extract;
- (c) filtering the pigeon dung aqueous extract, wherein the filtering includes filtering the pigeon dung aqueous extract through gauze to provide a filtrate and subsequently filtering the filtrate through filter paper;
- (d) preparing a silver nitrate aqueous solution, wherein 0.012 g AgNO3 is mixed with 50 ml distilled water and stirred for 15 minutes at 50° C.;
- (e) adding the solution to 5 ml of the filtered pigeon dung aqueous extract to form a mixture;
- and
- (f) resting the mixture to allow pigeon dung silver nanoparticles to form, wherein the pigeon dung silver nanoparticles have an average diameter of 135 nm and an absorption band at 454 nm on the UV-Visible spectrum.
