我们提出了一种利用自由支撑式空心纳米线制备纳米管膜的新方案，该方案具有尺寸容易控制的特点。采用金属-有机气相外延方法生长了GaAs-AlInP核壳纳米线，并将其部分嵌入到聚合物薄膜中。有选择地刻蚀了砷化镓芯材和衬底，使管子可以通向膜的两侧。用荧光显微镜观察了T4噬菌体DNA通过中空纳米线的电泳性运输。
We present a novel scheme for producing nanotube membranes using free-standing hollow nanowires, with easily controllable dimensions. GaAs-AlInP core-shell nanowires were grown by metal-organic vapor phase epitaxy and were partially embedded in a polymer film. The GaAs core and substrate were etched selectively, leaving tubes with open access to both sides of the membrane. Electrophoretic transport of T4-phage DNA through the hollow nanowires was demonstrated using epifluorescence microscopy.
