Hardware

PVA Hydrogel

We are the first iGEM project that successfully use PVA Hydrogel for B. subtilis whole -cell biosensor construction for higher effectiveness of hydrophobic toxin detection

Potential Implementation

Our hardware design, PVA Hydrogel, can help organisms grow according to experimental parameters and execute their engineered function.


Future iGEM teams could construct PVA Hydrogel as a new option for whole cell biosensors, especially if they are testing hydrophobic toxins.


Dry Lab

Modelling

Proposed method of using 2-step fit: GA and lsqcurvefit in MatLab for both global parameters space searching and local optimization.

Cereulide production model: give

Visualisation code for turning 2D to 3D matrix

Image thresholding and cropping
Simplified version of rotation matrix function
Visualisation using tinker

Circuit

The promoter PsinI reporter is tested by exposing the transformed B. subtilis to different concentrations of cereulide and its structurally similar ionophore, valinomycin


Characterization of PsinI-RFP reporter system (BBa_K4725012)

The behavior of the PsinI-RFP reporter system upon the addition of valinomycin and cereulide is characterized.
