Abstract:
A method for fabricating a 3D (three-dimensional) structure is disclosed to provide hydrophobicity to a surface of a 3D structure by using a dipping method in which a predetermined-shaped structure is immersed in a molten metal solution. The method includes: immersing a predetermined-shaped structure in a molten metal solution to coat a molten metal material on the surface of the predetermined-shaped structure; anodizing a metal base coated with the molten metal material; coating a polymer material on an outer surface of the metal-coated base to form a negative replica structure; covering an outer surface of the negative replica structure with an outer formation material; and removing the metal-coated base from the negative replica structure and the outer formation material.

A method for fabricating a 3D (three-dimensional) structure such that the 3D structure has a surface with hydrophobicity by using a metal foil such as an aluminum foil is disclosed. The method includes preparing a metal foil base by attaching a metal foil on an outer surface of a predetermined-shaped 3D structure; anodizing the metal foil base; coating a polymer material on the outer surface of the metal foil base material to form a negative replica structure; forming an outer structure by covering an outer surface of the negative replica structure with an outer formation material; and removing the metal foil base.
Abstract:
A molecular detection chip including a metal oxide silicon-field effect transistor (MOSFET) on sidewalls of a micro-fluid channel and a molecular detection device including the molecular detection chip are provided. A molecular detection method, particularly, qualification methods for the immobilization of molecular probes and the binding of a target sample to the molecular probes, using the molecular detection device, and a nucleic acid mutation assay device and method are also provided. The formation of the MOSFET on the sidewalls of the micro-fluid channel makes easier to highly integrate a molecular detection chip. In addition, immobilization of probes directly on the surface of a gate electrode ensures the molecular detection chip to check for the immobilization of probes and coupling of a target molecule to the probes in situ.
