Nanoparticles (NPs) are extensively investigated in recent years because of their potentials in catalysis, optical and electronic devices. For these NPs, the catalytic activity as well as their electrical, thermodynamic and chemical properties are dependent on their size and shape. The control over their morphology and size is thus an important aim. Generally, this is achieved by varying the synthesis method, reducing agent, stabilizer, temperature and pH in the reaction system. In this study, silver NPs are prepared using poly(vinyl alcohol) (PVA) and maltose as stabilizing and reducing agents, respectively. And silver NPs precursor is silver nitrate. We tried to confirm the effect of temperature and pH on the formation of silver NPs. The size distribution and diameter of PVA stabilized Ag NPs were observed by TEM and the reaction rate were characterized UV-vis spectrophotometer. And we investigated the effect of PVA stabilized silver NPs on in-vitro burn wound healing ability. |
