Previous iGEM teams have focused on genetically engineering bacteria to respond to novel inputs – for example light, or biologically significant compounds. There is an unmistakable need, therefore, to also develop clear, user-friendly outputs, especially for use with biosensors. The most popular output is the expression of a fluorescent protein, detectable using fluorescence microscopy.  However, how much easier would it be if we could simply ''see'' the output with our own eyes?

'''Sensor''': Our sensor system is sensitive to different concentrations of an inducer.

'''Adaptor''': The adaptor is an amplifier; its role in the system is to ensure large-scale production of the genes necessary for pigment production no matter the Pops input from the sensor.  This amplification acts as an "on" switch to guarantee maximum pigment production even with low level input.

'''Colour''': Pigment production
 
-
Thus, we can develop a population of mixed strains of bacteria.  The concentration of the inducer to which they are exposed determines which strains are activated to produce pigment.

The Cambridge 2009 iGEM team has created two kits of parts that will facilitate the design and construction of biosensors in the the future.

Previous iGEM teams have focused on genetically engineering bacterial biosensors by enabling bacteria to respond to novel inputs, especially biologically significant compounds. There is an unmistakable need to also develop devices that can 1) manipulate input by changing the behaviour of the response of the input-sensitive promoter, and that can 2) report a response using clear, user-friendly outputs. The most popular output is the expression of a fluorescent protein, detectable using fluorescence microscopy. But, what if we could simply see the output with our own eyes?

We successfully characterised a set of transcriptional systems for calibrated output - Sensitivity Tuners. We also successfully expressed a spectrum of pigments in E. coli, designing a set of Colour Generators.
