For the first time, the water soluble photoinitiator (PI) 4-(trimethyl ammonium methyl) benzophenone chloride was employed to make silver nanoparticles (AgNPs). Biosynthesis is another environmentally friendly way to make AgNPs. The PI/UV system, carboxymethyl starch (CMS), silver nitrate, and water were used in a new green synthesis technique. A mechanism was proposed for the reduction of silver ions to AgNPs using the PI/UV system as well as freshly formed aldehydic groups. UV-vis spectra and TEM of AgNPs colloidal solution were used to evaluate the synthesis process. CMS, PI, and AgNO3 concentrations of 10 g/L, 1 g/L, and 1 g/L, respectively; 40°C; 60 min; pH 7; and a material : liquor ratio of 1 : 20 yielded the greatest absorbance. The AgNPs were found to be stable in aqueous solution for three weeks at room temperature (25°C) and exhibit a round shape morphology. The diameters of produced AgNPs ranged from 1 to 21 nm, with the highest counts percent for particles measuring 6–10 and 1–3 nm, respectively.
