Abstract: A method of preparing an immunological substance detection nanowire complex includes preparing a multilayer nanowire in which a first metal and a second metal are alternately stacked, attaching a polymer, having a carboxyl group and an amine group at both ends of the polymer, to the second metal, attaching a first antibody, treated with a thiol's group, to the first metal of the multilayer nanowire, and attaching a second antibody to the second metal through the carboxyl group of the polymer. The second antibody includes a phosphor.

Abstract: A method for manufacturing a metallic nanospring includes preparing a nanotemplate having a nanopore and including a working electrode disposed on its one surface, preparing a first metal precursor mixture including ascorbic acid (C6H8O6), vanadium (IV) oxide sulfate (VOSO4.xH2O), and a metal precursor solution including a metal desired to be deposited, preparing a second metal precursor mixture by mixing the first metal precursor mixture with nitric acid (HNO3), depositing a metallic nanospring into the nanopore using electrodeposition by dipping the nanotemplate into the second metal precursor mixture and applying current between a counter electrode inserted into the second metal precursor mixture and the working electrode, and selectively removing the working electrode on the nanotemplate with the deposited metallic nanospring and the nanotemplate.
