A novel oligonucleotide microarray that can detect RNAs without fluorescent labeling of sample RNAs was developed. As a capture and detection probe, bispyrene-modified 2'-O-methyl oligoribonucleotide (OMUpy2), whose fluorescence was dramatically increased when hybridized with its complementary RNA, was adopted. Fluorescence of the OMUpy2 tethered on the glass surface was enhanced as much as 22-fold by the addition of complementary oligoribonucleotide.
