Hydrogels represent a versatile class of materials with remarkable potential as three-dimensional matrices for nanoparticle integration. This study explores the mechanism silver formation within polyacrylamide–alginate hybrid hydrogel, employing controlled reduction–oxidation reaction between nitrate (AgNO3) and sodium borohydride (NaBH4) across temperature gradient (5–70 °C). Characterization techniques, including Raman, infrared, UV-Vis spectroscopies, X-ray diffraction, scanning electron microscopy, were employed to analyze structural optical properties nanoparticles hydrogel. The results show that, rose, numbers decreased, while their size increased. Consistently octahedral in shape averaging 100–120 nm, these revealed temperature-dependent growth pattern, rare larger crystals emerging more frequently at higher temperatures. findings highlight hydrogels effective incorporation metal nanoparticles, paving way applications drug delivery, biosensing, antimicrobial treatments.
