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.
我们提出了一种使用独立式中空纳米线制造具有易于控制尺寸的纳米管膜的新方案。GaAs-AlInP 核壳纳米线通过金属有机气相外延生长，并部分嵌入聚合物薄膜中。GaAs 核和衬底被选择性地刻蚀，留下两端开口的纳米管。使用荧光显微镜证明了 T4 噬菌体 DNA 通过中空纳米线的电泳传输。
