Abstract
Citrate-stabilized silver nanoplates (AgNPs) were prepared via a seed-mediated method without surfactants, such as cetyltrimethylammonium bromide (CTAB), in a short amount of time (15 min). Silver seeds with 3–4 nm in diameter were added to a growth solution containing AgNO3, trisodium citrate (TSC) and L-ascorbic acid (AA). The size of the AgNPs depended on the concentration of the silver seed and TSC. The physical properties of the AgNPs were analyzed by transmission electron microscopy (TEM) and by an ultraviolet-visible (UV-vis) spectrophotometer. In addition, we tested the nanotoxicity of AgNPs prepared in TSC solution to the spleen of a rat, and found that AgNPs induced inflammation and white spots on the surface of the spleen.
