Polymeric thin biofilms of polyvinyl alcohol (PVA)/sodium alginate (SA) doped with a different mass fraction of synthesized selenium nanoparticles were successfully synthesized using traditional solution casting routine. Obtained samples were studied for their structural variations using Fourier transform infrared (FT-IR), and ultravilot/visible (UV/Vis.) spectroscopy. FT-IR spectral data reveals the appearance of spectral bands characterized the functional groups of both PVA and SA structural units in their positions. UV/vis. spectral data was employed to calculate the optical energy gap of prepared samples. Antibacterial tests against pathogenic bacteria were performed and correlated to the optical energy gap.
