Project Description



PixCell

Electrogenetics is a synthetic biology discipline developing electronic methods to control and measure gene expression. For PixCell we developed the first aerobic electrogenetic control system.

Using this system we demonstrated electronic control of gene expression and built a affordable custom-built electrode array which can be used as a tool for precise, programmable biological patterning.

We further improved our system by building a library of electrogenetic parts compatible with a variety of assembly standards. This is the first electrogenetic toolkit and has been characterised for “plug-and-play” manipulation of the transcriptional response to electricity.

Robust models of the system were developed so that electrogenetic circuits can be tested in silico before they are in vivo.

Using this library we developed a device with an important application in the field of biocontainment.

Electronic control

The ability to control gene expression in response to electronic stimuli is a very powerful novel tool.By developing this system to work in an aerobic system, for the first time,it has brought about exciting new applications that can be further developed upon. Not only does this project introduce a new system to control gene expression to iGEM but it also expands upon the current parts available to exploit the system. Electrogenetics is, like optigenetics and the others come before it, a new arrow in the quiver of control over gene expression.

Patterning

Separation of labour between different cell populations allows for more complex biological processes to be engineered. Whilst Ecolibrium demonstrated a method of maintaining a stable multicellular co-culture, PixCell addresses a further necessary condition of complex multicellular life: patterning. Without patterning animals, plants and fungi would not be complex forms of life but a cellular soup. As such spatial control of gene expression is of key importance to the development of complex synthetic biology.
