Abstract:
The present invention provides a biosensor and a method for detecting a target material using the same. The biosensor can quickly detect the target material, even in a small amounts. The biosensor includes the following: a receptor fixing part in which a receptor is fixed and a ferromagnetic substance is included; a magnetic field applying part which can apply an electric field with various directions to the receptor fixing part.
Abstract:
The present invention relates to a structure including an assembly of nanoparticles and polynucleotides and a method for producing same. In particular, the structure comprises: an assembly that is bonded to nanoparticles and large-scale DNA (the large-scale DNA has a bp length of 1,000-1,000,000, one side terminal bonded to the nanoparticles, and the other side terminal having a functional group that can be bonded to other nanoparticles or the outer surface); and a supported lipid bilayer (SLB) bonded to the assembly. The nanoparticle-large DNA assembly according to the present invention has a stable adhering force and linearized large DNA that is rolled in a coil shape by means of an external force (that is formed through an electric field or a fluid flow) so as to be widely used for DNA mapping or other DNA-related protein reaction analyses.
