Anisotropic Nanostructures with Bimetallic Nanocluster and Conducting Polymer Compartment for Photonics-based Biosensing process for producing the same and use thereof

摘要

The present invention relates to anisotropic nanostructures comprising a bimetallic nanocluster and conductive polymer block for photonics-based biosensing, that is, an asymmetric Janus nanoprobe for surface-enhanced Raman scattering (SERS)-based target material detection; a method for producing the same; and target material detection using the same. The asymmetric Janus nanoprobe according to the present invention significantly enhances an SERS characteristic from couplings among core-shell nanoparticles inside a metal nanocluster. In particular, by capturing a target in the polymer block, and measuring SERS in the metal nanocluster block, target detection and optical properties can be simultaneously enhanced. Accordingly, the asymmetric Janus nanoprobe of the present invention may be utilized as a functional nanoprobe for SERS-based biosensing.
