0.Construction of Biomolecular Rocket

Selective coating by vapor deposition

    In order to have a positional specificity, We make metal-deposited beads. Hemispherical part of polystyrene bead is covered with Cr, 1/4 part of spere is covered with Au and the other part is polystyrene. First, deposit Au on the half of polystyrene beads. Second, deposit Cr on the half of polystyrene beads.

DNA conjugation to polystyrene surface

    Carboxyl (COOH) microparticles can be used for covalent coupling of proteins by activating the carboxyl group with water-soluble carbodiimide. The carbodiimide reacts with the carboxyl group to create an active ester that is reactive toward primary amines on the DNA.
    First, carboxyl group of polystyrene beads and EDAC react with each other. Next, carboxyl group become active intermediate. Then DNA coupled to polystyrene beads.

DNA conjugation to metal surface

    When we mix thiol-modified DNA and Pt or Au, they will be self assembly. Thiol-modified DNA and Au or Pt are organized naturally. Using this characteristic, bond two kinds of DNA with Pt and bond another kind of DNA with Au.

Catalyst conjugation

     Finally, we conjugated the catalyst to our rocket body by DNA hybridization. Complementary strand DNA had adhered to the corresponding parts of the rocket body, so it enabled to conjugate catalyst engines in that we designed these DNA were thermodynamically stable when they hybridized.     we build our rocket in this way.
