ABSTRACT:
This invention attempts to provide a method for producing a DNA chip which can be accomplished in simple steps at a low cost, and wherein use of the resulting DNA chip reduces loss of probes and sample substances in the washing step enabling efficient use of such probe and sample. This invention also attempts to provide a DNA chip produced by such method. Accordingly, a method for producing a DNA chip comprising a substrate and a DNA-binding layer formed on the substrate wherein said DNA-binding layer is a diamond like film having a DNA-binding group is provided, and this method comprises the steps of: reducing pressure of a vacuum chamber to a predetermined degree of vacuum; feeding the chamber with a gas which is the source of said diamond like film; feeding the chamber with a gas which is the source of nitrogen; and forming the diamond like film having a DNA-binding group on the substrate by CVD. Also provided is the DNA chip produced by such method.
