Abstract

Analyte detection is a major component of fieldwork, environmental surveillance, and health protection, but lack of resources or access to instruments can create challenges in technology-limited environments such as remote research sites or low- and middle-income countries (LMICs). Whole-cell yeast-based biosensors provide potential solutions to these barriers. Here, we discuss the components of whole-cell yeast-based biosensors, emphasizing the process by which they are designed for their analyte of interest, approaches for harnessing them to function in particular research environments, and their advantages and disadvantages relative to other analytical tools. We provide examples of the various purposes for which existing whole-cell yeast-based biosensors have been used, focusing most on those appropriate for detecting externally-generated analytes in technology-limited settings. The further development of field-friendly whole-cell yeast-based biosensors still faces challenges, including the need to reduce the time from contact with the analyte to signal readout of the biosensor. Regardless, the inexpensive, robust, portable, environmentally friendly, and highly modular nature of yeast-based biosensors suggests that they could become useful tools for a range of analytical tasks.
