초록/해제  
요약Accurate measurement of biomarkers is critical for properly assessing and managing disease, but standard methods for biomarker quantification involve laborintensive protocols and expensive equipment that make disease diagnosis difficult in resource-limited settings. The development of rapid, sensitive, and specific sensors that can be used at the point of care could increase testing accessibility in low-resource areas and have an immense impact on global health. While cell-free synthetic biology allows us to design powerful yet accessible biosensors, the range of detectable analytes is limited due to constraints in existing sensor frameworks.This thesis describes my work in developing new platforms to broaden the range of detectable analytes for cell-free biosensors. Specifically, I engineered the first highly adaptable biosensing platform for low-cost protein detection. I also broadened the application space of RNA toehold switch activators and repressors to include shorter RNA inputs. These findings have a strong potential impact in microRNA sensing applications, a space where cell-free expression systems previously had little footprint. Lastly, I describe progress towards a revolutionary new biosensing platform that couples structure-switching DNA aptamers with RNA toehold switches. This technology would enable biosensor construction for virtually any biomarker. Taken together, this work presents several advances in cell-free biosensors that make it possible to detect previously undetectable analytes.
