| Popis: | A facile, eco-friendly and green synthesis method was used to prepare spherical silver nanoparticles (AgNP) with ~5.6 ± 1.5 nm diameters using Lilium casa blanca (LCB) petals. Synthesized AgNP showed good antioxidant and surface enhanced Raman scattering (SERS) activities. After reacting at 37 °C for 12 h, 10 mg LCB petal's biomass with 5 mL 5 mM silver nitrate solutions at pH 12, became a golden color with a characteristic absorption peak at 410 nm. The conversion rate of Ag+ to Ag0 reached 98.3%. The formation of AgNP was due to the combined action of several reducing substances in the LCB petals. Antioxidant and SERS activities of the AgNP were also obtained. ABTS, FRAP and RP assays all showed that AgNP had good antioxidant activity in comparison with the antioxidant activity of LCB petals. AgNP also showed good SERS activity. |
