Ag nanoparticles incorporated onto flour (F)/polyvinyl alcohol ( PVA ) were performed by green synthesis using gamma irradiation to form (F/ PVA /Ag) bio‐based nanocomposite hydrogel. The effect of the hydrogel composition and irradiation dose on the gelation percent was investigated. Characterization of (F/ PVA ) and (F/ PVA /Ag) by Fourier transform infrared spectroscopy and thermogravimetric analysis was was investigated. The formation of Ag nanoparticles in (F/ PVA /Ag) was confirmed by UV –Vis spectra, X‐ray diffraction, and transmission electron microscopy. The (F/ PVA /Ag) nanocomposite exhibited excellent antibacterial activity against the gram‐positive bacteria Staphylococcus aureus ( ATCC 29213) and moderate activity against the gram‐negative bacteria Escherichia coli ( ATCC 25922). It exhibited excellent antifungal activity against Candida albicans ( ATCC 10231). The results proved that this novel developed (F/ PVA /Ag) naocomposite has a great potential for use in biomedical applications such as wound dressing hydrogel.
