e-oscillators

Two genetic oscillators, dual-feedback oscillator and quorum-sensing oscillator, are built in our wetlab, so we first analyze the important biological processes and construct ODE sets to simulate these two oscillators separately. However, due to the time interval between the expression of regulating protein and their binding to promoters, we improve our models more precise by DDEs. Once the better genetic oscillator is selected through experiments, we will adopt the corresponding one as the virtual part.

Quorum-sensing oscillator

We transformed the three devices into competent cell (DH 5 alpha) and measured fluorescence as well as optical density of the LB medium at the suitable period (We did pre-experiment before formal experiment for confirming the suitable period as well as the dilution factor), using a plate reader, respectively. We hypothesized that the GFP expression quality of the three devices level is Device 1, Device 2, Device 3, respectively. And our final result accord with our hypothesis.
