通过在多孔聚合物膜的孔壁上无电沉积Au来制备金纳米线和纳米管。支撑膜中的孔充当纳米结构的模板。载体是具有圆柱形纳米级孔的市售纳米多孔聚碳酸酯过滤器。我们已经表明，通过控制Au沉积时间，可以制备Au纳米管（短沉积时间）或纳米线（长沉积时间）。金纳米线和纳米管膜可用于纳米电极系综、分子过滤器和化学开关。
Gold nanowires and nanotubes are prepared via electroless deposition of Au onto the pore walls of a porous polymeric membrane. The pores in the support membrane act as a template for the nanostructures. The support is a commercially available nanoporous polycarbonate filter with cylindrical nanoscopic pores. We have shown that by controlling the Au deposition time, Au nanotubes (short deposition times) or nanowires (longer deposition times) can be prepared. The gold nanowires and nanotube membranes can be utilized for nanoelectrode ensembles, molecular filters and as chemical switches.
