How can we use the results we obtained from the experiments and the model to create a wavelength biosensor?

This is how we propose that the system would work:

From experiments we have characterised this trend of our initial system:

boarder

We can achieve this through fusing different fluorescent proteins onto the system.Through the characterization of the system, we have a model which shows us:


We also know that different fluorescent proteins have different excitation wavelengths.


Say if we fused EGFP (488nm) onto the LacZ gene.


1. When we shine a blue light of 400nm onto our system, the LacZ activity in the system is high, but the wavelength of the light is not high enough to excite the fluorescent protein.

2. The system will have an initial system that is switched on, but an EGFP that is switched off. Therefore the overall system is switched off


3. However if we shine a blue light of 500nm onto our system, the activity of the LacZ is high and the EGFP is also activated and so we have an overall system that is switched on

Through this method, we can fuse several fluorescent protein with different excitation and emission wavelengths and therefore get a system that can respond to different wavelengths.
