Title:
BIOSENSOR USING DNA-BASED CONDUCTIVE NANOWIRE AND FABRICATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/174329
Kind Code:
A1
Abstract:
The present invention relates to a biosensor using a DNA-based conductive nanowire and a fabrication method therefor and, more particularly, to a biosensor able to determine the onset of a disease at high sensitivity, using a DNA-based conductive nanowire, the biosensor comprising: a DNA-based conductive nanowire formed by coating with conductive nanoparticles which are spontaneously positively charged; and a protein detection receptor coupled with the DNA-based conductive nanowire by electrostatic attraction, and a fabrication method therefor. A biosensor using a DNA-based conductive nanowire according to the present invention is fabricated by a fabrication method comprising: a DNA alignment step (S100) of selectively aligning DNA on a substrate, a DNA-based conductive nanowire manufacturing step (S200) of coupling the aligned DNA with positively charged, conductive nanoparticles to manufacture a spontaneously, positively charged DNA-based conductive nanowire, and a protein detection receptor immobilizing step (S300) of immobilizing a receptor for detecting a protein to the DNA-based conductive nanowire.
