Our Team

The UW iGEM team is a very interdisciplinary group. Our team members span the four faculties of Science, Mathematics, Engineering, and Applied Health Studies and include the programmes of Biology, Computer Science, Bioinformatics, Computer Engineering, Electrical Engineering, Chemical Engineering, and Mathematical Physics at undergraduate and graduate levels. Even our professor advisors are cross-appointed to two other faculties. Our diverse backgrounds bring together a wide range of skills and ideas to the iGEM project. iGEM is giving us the opportunity to learn.

Our Design

Our project is a light-controlled 1-bit adder.

The Inputs

We will be using red light as one of the inputs and blue light as the other. The red light will be detected by the previously used Cph1/EnvZ fusion protein ([http://partsregistry.org/Part:BBa_I15010 BBa_I15010]).

The blue light input will be derived from the Myxococcus xanthus carotenogenesis system, a list of relevant references can be found below. In the event this input should prove difficult to implement, we will use a chemical input instead.

We have chosen to use light as an input for many reasons: it does not require altering the media, it can be turned on and off rapidly, and it has extremely high resolution and accuracy.

The Logic Gates

In order to have a functional adder, we are designing an AND gate aswell as an XOR gate.
