We’ve made our entire system <b>modular</b>, where we trigger the succession of events using this control system. Here, we have tackled a drug delivery problem, but this "Black box" approach can be applied to any other system. This is our <b>novel engineering approach</b>, which is extremely <b>reusable</b> in synthetic biology.
-
We’ve made our entire system modular. Each module can essentially be pictured as a blackbox with one temporal control input and one output. Therefore, each module is linked to the next module by temporal control. Temporal control has allowed us to create a system that can be reused in other projects in synthetic biology. It is in fact a novel engineering approach that is both reusable and elegant.

In our temporal control system, we have employed 3 kinds of temporal control:

In our case, thermoinduction was necessary, as chemical induction may be blocked by the presence of the capsule (that inhibits diffusion).

The idea to link each module by a temporal control is developed such that we can use adapt this method other systems, by simply changing the contents of the blackboxes / modules.

[[Image:II09_diax_wolf.jpg | left]]We have modelled autoinduction by a number of models, and we hope that experimental results will confirm which model is most applicable to our system.
 +
 +
 +
The first of our diauxic growth models is a cybernetic model developed by Kompala et al [1]. This model shows that glucose (S1) is used up before the secondary carbon source (S2). During this phase, the population (X) is in exponential grow until glucose (S1) runs out. This is followed by a stationary growth phase, and finally the population enters a second exponential growth phase as they start uptaking the secondary carbon source (S2).

Temporal Control


Engineering Approach to Module Integration by Temporal Control

This temporal control platform showcases our engineering approach in the E.ncapsulator project. It allows us to integrate all our modules in a simple and elegant way.

We’ve made our entire system modular, where we trigger the succession of events using this control system. Here, we have tackled a drug delivery problem, but this "Black box" approach can be applied to any other system. This is our novel engineering approach, which is extremely reusable in synthetic biology.

  About the timeline, its explainations, and to view our testing construct.




Conclusion

Module integration has allowed us to link all our modules together, to create a working network.

It also allows us to showcase the advantages of synthetic biology as the marriage of engineering with biology. By integrating the engineering principles of reusability and simplicity of system, we have developed this platform to program biologcal systems.
