<h3 id=Flower>Second stage: Amplification system</h5> <h4 id=sensing>2-1 DNA Origami approach</h4> <h5 id=5>2-1-1 Making DNA Origami</h5> <h5>Making DNA origami</h5> <h6>DNA origami recipe</h6> We designed DNA origami by <A Href="http://cadnano.org/">caDNAno2</A>, software for designing 2D and 3D DNA origami.<br> Our DNA origami has 141 staples that have 30nt free single-stranded parts outside the DNA origami. The sequence of the parts is “<font color="#00a0c0">each DNA origami staple</font>-TTTTTTTTTTTTTTT<font color="red">CTGTCGCATCGAGAG</font>”.<br> Between the staple and unique (<font color="red">CTGTCGCATCGAGAG</font>) sequences, 15 T bases are inserted. They are to make a T loop. Thanks to this T loop, single-stranded DNA complementary to the unique sequences (such as Origami-anchor DNA) are expected to easily hybridize with the unique sequence.<br> The 30nt single-stranded parts are stable till 37°C, according to <A Href="http://www.nupack.org/">NUPACK</A>).<br> The 141 staples have the same length so that they may be present at the same intervals in the DNA origami.<br> Each side of our origami is not fully covered with staples, and single-stranded M13 remains. This is for preventing π-π interaction and stacking by hydrophobic interaction between base pairs of double-stranded DNA.<br> This design enables each DNA origami to exist individually.<br> <br> <h6>The list of strands</h6> The other strands exept DNA origami staples used in our experiment are shown in Table2.<br> The sequence of Origami-anchor DNA is shown below (at the first sequence in Table2). For labeling, we also attached fluorescent-tagged DNA (at the second in Table2) to our DNA origami.<br> To hybridize both Origami-anchor DNA and fluorescent-tagged DNA with the same unique single-stranded parts of our Origami, we arranged two kinds of adaptor DNA (at the third and fourth in Table2). One adaptor has complementary sequences to both the unique sequence and Origami-anchor DNA. The other has complementary sequences to both the unique sequence and the fluorescent-tagged DNA. Thanks to these two adaptors, two different strands can bind to the same unique sequence. <br> <br> <table border cellspacing="3" bgcolor="lightyellow"> <tr bgcolor="lightyellow"> <td> The kinds of DNAtrands </td> <td> Its sequence </td> </tr> <tr bgcolor="moccasin"> <td> Origami-anchor DNA</td> <td> CCAGAAGACG </td> </tr> <tr bgcolor="moccasin"> <td> Fluorescent-tagged DNA </td> <td> ACTAGTGAGTGCAGCAGTCGTACCA </td> </tr> <tr bgcolor="moccasin"> <td> Adaptor strand for Origami-anchor DNA and the unique sequence in DNA origami </td> <td> CGTCTTCTGGCTCTCGATGCGACAG </td> </tr> <tr bgcolor="moccasin"> <td> Adaptor strand for fluorescent-tagged DNA and the unique sequence in DNA origami </td> <td> TGGTACGACTGCTGCACTCACTAGTCTCTCGATGCGACAG </td> </tr> </table> <div class="captiontable">Table2 The sequence of the strands</div><br> <br> <h6>Annealing of DNA origami</h6> The annealing solution is shown in Table3.
