Digital Barcode Nano-Wire and System for Bio-Sensing Using the Same

A digital barcode nano-wire, comprising:

• a hard magnetic segment showing digital information;
• a non-magnetic segment showing digital information different from the hard magnetic segment;
• and
• a spacer that is disposed between the hard magnetic segment and the non-magnetic segment, between the hard magnetic segment and the hard magnetic segment, or between the non-magnetic segment and the non-magnetic segment, and that does not show digital information;
• and
• a coating film coating the hard magnetic segment, the spacer and the non-magnetic segment surface with gold (Au) or silver (Ag),
• wherein detecting biomolecules for combining with probe biomolecules formed on a surface of magnetic nano particles are formed on a surface of the coating film.

A bio-sensing system in a fluidic state, comprising:

• a nano-wire inlet introducing a digital barcode nano-wire;
• a sample inlet introducing a sample;
• a hybridizing means forming a hybridized digital barcode nano-wire with the attached sample and a non-hybridized digital barcode nano-wire without the attached sample by hybridizing the digital barcode nano-wire and the sample;
• an aligning and sorting means transmitting the hybridized digital barcode nano-wire to a hybridized channel and transmitting the non-hybridized digital barcode nano-wire to a non-hybridized channel by separating the hybridized digital barcode nano-wire and the non-hybridized digital barcode nano-wire;
• an encoding means for encoding the separated hybridized digital barcode nano-wire;
• and
• a decoding means decoding the encoded hybridized digital barcode nano-wire.
