简介:传导性的Au-biopolymercomposites在象神经织物那样的织物工程有有希望的应用新生。在这研究,丝绸丝心蛋白nanofibers被调整丝绸在水的答案形成自己组装进程然后为Aunanowire用作模板制造。我们由重复播种周期执行了Au种子的合成因为若干次Au的密度在nanofibers上播种以便增加。在无电的plating以后,浓密地装饰了种子种了进跟随丝绸nanofiber充满在粒子之间的差距并且最后形成一致连续nanowires的不规则地塑造的粒子的Au。Au丝绸丝心蛋白nanowires的传导性的性质被学习与当前电压(IV)测量。典型欧姆的行为被观察,它在神经织物新生加亮他们的潜在的应用。
简介:Aunanoparticles装饰了graphene(AuNPs@Gr)/nickel泡沫(Gr/NiF)nanocomposite(AuNPs@Gr/NiF)被AuNPs的electrophoretic免职在Gr/NiF上跟随的化学蒸汽免职准备。形态学,微观结构和同样准备的AuNPs@Gr/NiFnanocomposite的察觉到的性能被描绘并且测量,分别地由扫描电子显微镜,传播电子显微镜,紫外可见光谱学和化学工作站。同样准备的AuNPs@Gr/NiFnanocomposite被用作电极为氢过氧化物的察觉构造一个化学传感器(H2O2)。结果证明AuNPs在Gr/NiF的表面上同质地并且稳定地散布了。化学传感器展出敏感、选择的表演到H2O2.
