Abstract
Starch as capping molecule has been used increasingly as part of the green chemistry concept of synthesis and in this work is used to stabilize silver selenide nanoparticles. The influence of extraction time and capping agent concentration were studied to investigate their effect on the size of the synthesized nanoparticles. Silver selenide has good potential in antibacterial activity but that depends on the shape and sizes of the nanoparticles. The FT-IR and UV-visible spectroscopy, TGA, TEM and XRD techniques have been used to characterize the prepared silver selenide nanoparticles. The prepared nanoparticles gave size distribution of the diameters of 1-9 nm. The size of nanoparticles was found to decrease with an increase in extraction time 0 to 20 h. With an increase in the concentration of starch, 0.025 to 0.1 w/v, nanoparticles size decreased and then increased at higher capping concentration, which was due to ripening effect.
