Nanobiotechnology is a highly promising domain within contemporary technology and nanoscience. Nanoparticles of metal are utilized in various applications across multiple domains, including agriculture, medicine, electronics, and catalysis. Silver nanoparticles were synthesized using Typha domingensis extract, an essential component in nanotechnology, to address the high cost and low biocompatibility associated with chemically and physically synthesized nanoparticles. This research aimed to explore the feasibility of synthesizing silver nanoparticles (Ag-NPs) using an aqueous extract of Typha domingensis. The synthesized Ag nanoparticles were characterized using SEM, EDX, XRD, and UV-vis spectroscopy. The produced colloidal silver solution exhibited maximal absorption at 243 nm in UV-vis spectroscopy, with the best findings obtained at pH 9 and 45°C, and the silver nanoparticles had a spherical form with an average particle size of 31–69 nm, according to the X-ray diffraction and analysis. At concentrations of 25%, 50%, and 75%, the antibacterial activity of silver nanoparticles was examined against Escherichia coli and Pseudomonas aeruginosa (Gram-negative), and Staphylococcus aureus and Streptococcus (Gram-positive). The results showed that silver nanoparticles inhibited bacterial growth.
