Microbial biosensors are at the forefront of biotechnology, harnessing the natural abilities of microorganisms to detect environmental changes and contaminants. Recent advancements in cell culturing, genetic engineering, and synthetic biology have significantly enhanced the biosensing capabilities of microbes, enabling applications in environmental surveillance, food safety, and biomedicine. This collection includes methods for engineering and developing microbial biosensors, including non-conventional microbial chassis. It also covers novel analytes that can be detected by microbial biosensors, as well as the development of genetic circuits to connect these analytes or combinations with cellular responses. 

Furthermore, the collection delves into advanced techniques for optimizing microbial biosensors, such as improving analyte sensitivity, specificity, and readout speed. For real-world applications, the collection covers recent innovations in translating microbial responses into easily detectable signals and reliable biocontainment technologies, such as encapsulation or kill switches, to prevent the unintended release of genetically modified microbes into the environment.
