Patent ID: 8414965

Claim:
A method for manufacturing a substrate of an analytical sensor, said method comprising: (a) the step of preparing a dispersed solution of nanoparticles by surface-modifying said nanoparticles with an organic functional group and dispersing such surface-modified nanoparticles in a volatile organic solvent; (b) the step of preparing a single layer film of the nanoparticles surface-modified with said organic functional group using said dispersed solution of nanoparticles on the basis of the Langmuir-Blodgett method, and then transferring said single layer film of nanoparticles to the substrate; (c) the step of coating the substrate to which said single layer film of nanoparticles is transferred, with a metal thin film by means of vacuum vapor deposition; and (d) the step of removing nanoparticles after coating with the metal thin film by means of the vacuum vapor deposition.
