Testing for genetically modified organisms (GMOs): Past, present and future perspectives

Abstract This paper presents an overview of GMO (Genetically Modified Organisms) testing methodologies and how these have evolved and may evolve in the next decade. Challenges and limitations for the application of the test methods as well as to the interpretation of results produced with the methods are highlighted and discussed, under consideration of various [...]

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, [...]
