Abstract :
A biosensor is a bacterium that is genetically modified to produce fluorescent proteins when exposed to environmental pollutants. In this paper, we investigate the possibility of estimating the concentration of environmental pollutants in a sample by using non-specific biosensors. To do that, we first propose an experimental procedure allowing to obtain three-way fluorescence data sets. The extraction of bio-sensor response to changes in environmental pollutant concentrations will be achieved by Candecomp/Parafac. This allows the estimation of multiple environmental pollutant concentrations using calibration curves of biosensors.
