Application

使用银纳米线配制水基油墨。已对导致更多可洗脱物质的银纳米颗粒进行研究。 对银纳米颗粒 (AgNPs) 的免疫佐剂作用进行了体外 和体内 研究 制造了基于银纳米颗粒的石墨环氧纳米复合材料。 有研究表明,AgNP 可通过增加血小板聚集和促凝血活性促进血栓形成。已制备 AgNP 光致沉积的光纤传感器。 含 Ag 和羟基磷灰石作为纳米添加剂的 PAN 纤维基纳米复合材料已有报道。

General description

这种纳米银粉由直径小于100 nm的金属银纳米颗粒组成。这些纳米银颗粒包被有质量浓度为0.2%的聚乙烯吡咯烷酮(PVP)。这种涂层有效地抑制了表面氧化,并增强了粉末在各种溶剂中的分散性。

纳米银粉在医学应用和医疗器械中得到了广泛应用。纳米银的表面积体积比增加、反应性提高,使其在现代生物医学应用中特别有价值,特别是在医疗器械涂层中。
