Mission
Now that there are many tablet computers, our goal is to create the world's smallest tablet ! We are designing and constructing 15x15 pixel display made of DNA origami. We aim to show animation on that display, using bistable system.
Bistable System
What is Bistable System?
Bistable system enables us to express two exclusive states, using network of chemical reaction.
For example, we represent two states by materials A and B. Bistable system uses reaction network like right picture. In this network, A promotes production of A itself and iB(i means inhibition), and B promotes B itself and iA. On the other hand, iA inhibits production of A and iB inhibits production of B. There are also reactions that decompose A, B, iA, and iB.
If A is even bit more than B, this network promotes production of A and decomposition of B (detail is shown in Simulation). Afterwards there will be only A and vice versa. Thus bistable system make two states "There is only A" and "There is only B".
Method
To realize bistable system, we used DNA.
- production of A,B,iA,iB
- inhibition of production of A,B
- decomposition of A,B,iA,iB
DNA tablet
- the DNA tablet shows you the two different pictures in response to its environmental change.
