  • 1st Deposition
  1. increase the pressure in Bell jar.

<energization>
※Au can't connect with polystyrene beads, so we deposit Au after Cr.
5. increase electric current slowly.
6. (Cr) 1st: stop at 15 A and keep 30 seconds. / 2nd: stop at 15 A and keep 50 seconds.
(Au): confirm melting at 8 A and keep 11 A until all Au has evaporated.
7. off electric current
8. cool down
9. increase pressure
10. take out the sample
11. vacuuming (to 1.0×101)
※※
  1. wash the surface of the cover glass with 70% ethanol.
  2. wash the surface of the cover glass with 70% ethanol.
  3. pipette 70% ethanol and polystyrene-beads into a 2.0 mL tube.
  4. centrifuge the tube by tabletop centrifuge.
  5. remove supernatant.
  6. repeat 3 to 5
  7. extend the polystyrene-beads over a cover glass.
  8. dry the cover glass.

Way to hybridize DNA

  1. Irradiate visible-light (blue-light λ > 400 nm) to solution A and B for 5 minutes with Visible-light irradiation equipment (Epi-Green Slim pro S) to stabilize trans-azobenzene
  2. mix 40 µL of each solution under the visible light
  3. irradiate visible light for 10 minutes again
  4. Put solution into dark box at 4°C for 12 hours to cool down for hybridization

Irradiate UV-light to DNA duplex and measures absorbance

  1. Irradiated UV-light (365 nm, 30 mW/cm2) to a solution A+B for 1, 5 minutes
  2. Measured absorbance of each DNA solutions (1~5) near 260 nm wavelength of light. The Abs of each DNA solution we measured was as follows (table below).
