Method for making polymer single nanowires and sensors utilizing the same |
摘要 |
A method of fabricating polymer single nanowires, comprising the steps of: spin coating a polymethylmethacrylate resist onto a silicon wafer patterned with at least one gold electrode pair; creating a nanochannel using e-beam lithography between each pair of the at least one gold electrode pairs; placing the silicon wafer into an aniline monomer polymerization solution; reacting the polymerization solution to give a coated wafer and a polyaniline film; and cleaning the coated wafer of polymethylmethacrylate resist and polyaniline film to give at least one gold electrode pair with a connecting polymer single nanowire. |

1. A method of fabricating a plurality of polymer single nanowires having elevated surface to volume ratios, comprising the steps of:
spin coating a polymethylmethacrylate resist onto a silicon wafer patterned with a plurality of gold electrode pairs; creating a nanochannel using e-beam lithography between each pair of the plurality of gold electrode pairs; placing the silicon wafer into a first solution maintained at a temperature between 0° C. and 5° C. and comprising an aniline monomer in an aqueous perchloric acid; reacting the first solution with a second solution maintained at a temperature between 0° C. and 5° C. and comprising ammonium persulfate in an aqueous perchloric acid to give a polyaniline film coated wafer; and cleaning the polyaniline film coated wafer of polymethylmethacrylate resist and polyaniline film to give a plurality of gold electrode pairs with a connecting polymer single nanowire having an elevated surface to volume ratio between each of the plurality of gold electrode pairs. |
