Synthetic biosensing systems

Abstract An essential feature of synthetic biology devices is the conversion of signals from the exterior of the cell into specific cellular events such as the synthesis of a fluorescent protein…In the future, completely artificial signaling pathways will give us the possibility to control cellular processes in a direct, precise and reliable way. At present, [...]

Applications of whole-cell bacterial sensors in biotechnology and environmental science

Abstract Biosensors have major advantages over chemical or physical analyses with regard to specificity, sensitivity, and portability. Recently, many types of whole-cell bacterial biosensors have been developed using recombinant DNA technology. The bacteria are genetically engineered to respond to the presence of chemicals or physiological stresses by synthesizing a reporter protein, such as luciferase, β-galactosidase, [...]
