cube3d.dna

The most advanced and compact 3d engine ever implemented in DNA code.

How to deploy

1. Synthesize the oligonucleotides from the cube3d.dna file.
2. Arrange the test tubes as shown in the diagram below.
3. Don't forget to provide the initial concentrations according to the table below.
4. Use a pipette to encode the position (row and column) of each tube to start the computation.

Environment variables

q = 0.01
cxtm = 0.606
axp = 0.606
cytm = 0.898
ayp = 0.898
cztm = 1.243
azp = 1.243
mxyzm = 0.3
nx = 0.036 + 0.555 Col + 0.147 Row
ny = 0.853 + -0.517 Row
nz = 0.737 + -0.270 Col + 0.302 Row

Testing

1. Pick the fluorophore of your favorite color and attach it to the Strand R0, so that it activates when the R species are being produced.
2. Use a light source with a specific wavelength (depending on the fluorophore you've chosen) to render the result.

Disclaimer: perhaps it would not be a good idea to try this experiment in a real lab, because it will cost you a lot of money and most likely won’t work as intended the first time.

10 reactions after the minification used in this project. Since the piperine compiler doesn't support more than 2 products on the right-hand side, the reactions were split.	CRN++ 70 reactions output for comparison (CRN++ is not used in this implementation).

Building from source

1. Install the piperine compiler by the DNA and Natural Algorithms Group.
2. Run the following command

piperine-design cube3d.crn --maxspurious 0.765

3. Wait 2-3 hours for the compilation results.
