An oxidative stress-specific bacterial cell array chip was fabricated and implemented in the analysis of various different chemicals. The chip consisted of twelve toxicity responsive strains that respond specifically to different oxidative toxicities such as the generation of the superoxide radical, except for strain EBMalK, which was included as a negative(More)
In this study, we describe a straightforward strategy to develop whole cell-based biosensors using fusions of the bacterial bioluminescence genes and the promoters from chemically responsive genes within Escherichia coli, in which chemical target-responsive genes were screened by using the information of gene expression data obtained from DNA microarray(More)
