BIOCHIP AND METHOD FOR MANUFACTURING THE SAME

摘要

Disclosed are a biochip and a method for manufacturing the same. The biochip comprises a substrate; a thin metal pattern formed on the substrate by patterning a metal solution with an inkjet printer; and a biomaterial immobilized on the thin metal pattern via a linker. The biochip, in which a thin metal pattern is freely formed through an inkjet printer, allows biomaterials to be formed in various patterns. The thin metal pattern, which can be easily formed in an inkjet printing ejection manner, can be produced in a mass scale. Also, the apparatus for manufacturing the biochip of the present invention is small and inexpensive. Further, thin metal pattern can be formed to a size as small as micrometers so that biomaterials can be integrated at high density. In addition, the method is environmentally friendly because there is no need to carry out a washing process for an etching process. No limitations are imposed on the kinds of the metal that can be used in the present invention, and silver can be used, which results in an improvement in the adhesiveness of the substrate to the thin metal pattern as well as in the immobilization efficiency of biomolecules.
