Abstract
(Figure Presented) Ultrasensitive DNA detection using enhanced two-photon excited fluorescence: DNA detection systems formed on a highly regular gold nanopattern over a large area show enhanced sensitivity from high to ultralow concentrations (∼10-11 M, see figure) target molecules. The observed two-photon excited fluorescence on the gold patterned surface is enhanced over two orders of magnitude compared with the molecules on the glass surface.
