The development of a durable and efficient composite material that could perform a long-life antibacterial activity and radical scavenging ability is highly needed. In this paper, selenium nanostructures of different morphologies were synthesized by a wet chemical method under mild experimental setup. Silver nanoparticles were doped on the surface of these nanostructures and successfully characterized by X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray, and high-resolution transmission electron microscopy. The potential applications of the designed composite were investigated in multiple disciplines including antibacterial, antioxidant, and photocatalytic activities. The selenium silver (Se-Ag) nanocomposite was employed as an antibacterial agent against a Gram-positive bacterium and a Gram-negative bacterium, and our findings disclosed that the designed composite is an excellent material in inhibiting the challenged bacterial strains. The Se-Ag composite has shown excellent activity with 30-mm inhibition zone at 2 mg/ml concentration, and maintains significant antibacterial efficacy for 72 h, indicating its sustainable performance for a long-life period. Furthermore, Se-Ag nanocomposite also exhibited a significant radical scavenging property against 2,2-diphenyl-1-picrylhydrazyl free radical and an enhanced photocatalytic activity (90-95%) with complete dye decolorization in 70 min. The superior antibacterial activity (zone of inhibition 30 mm), photocatalytic (95%) and antioxidant performance (78%) of the nanocomposite are due to the combined antibacterial (17 mm), photocatalytic (~ 30%) and antioxidant potentials (15%) of the Ag and Se (16 mm, 40%, 25%), respectively.
