The Van2 Biosensor in vivo characterisation. a. Representation of the Van2 biosensor design. b. The Van2 Biosensor in E. coli RARE strain was induced with increasing concentrations of vanillin. The fluorescent gene expression normalised to cell density (RFU/OD₆₀₀) was plotted. Each value represents the mean and standard deviation of 3 biological replicates
