Abstract
A DNA chip (or PNA chip) composed of a solid carrier and plural DNA fragments (or PNA fragments) fixed onto is the solid carrier at each one end, wherein a plurality of short chain spacer molecules having a hydrophilic moiety at each one end are fixed at each another end onto a surface of the solid carrier having no DNA fragments (or no PNA fragments) on its surface is effective for high sensitive quantitative analysis of a nucleic acid fragment complementary to the DNA fragment (or PNA fragment).
