When our creative minds get captive of the imagination, fantasy and unlikely ideas flourish inside us, commonly named imaginations. Whereas great inventors of History had to decide if their imaginations worth it or not in order to work on them, we rely on Modeling. Still implausible ideas being represented by equations, can transform imagination in reality, as it happened with AladDNA. Using knowledge from Biology and Engineering, biological processes already known become pieces of a puzzle which results in innovative designs that perform new functions. Modeling AladDNA has not only confirmed that our idea is feasible, it has also undressed its mechanism. Whereas wet lab experiments need inexistent time to depict our system’s performance, Modeling has been a headstone of our project, allowing us to know with depth the behavior of the circuit and becoming deadlines in feasible dates.

We started by figuring out how it should work in a tree diagram, keeping the idea simple:

Basically, our aim is the biological design of a decoder that only expresses the codified genetic information when, where and which is desired by the user. The biological components that allow us this implementation in living organisms are two switches, two recombinases and a library of different binding domains. All those elements have been coordinated in this cascade of three different levels.

Our deterministic model uses mathematical information contained in its equations, in order to provide results that depict the behavior of our device. After deterministic model, it is time to test our biological machine in different conditions.

One of the main points when innovative devices are being tested, is “how”. How does AladDNA behave? This is the main question that we want to answer with our modeling task.

Take a sit and enjoy this wander in our mathematical chaos!
