Savagatrup Suchol, et al. "Bio‐Inspired Carbon Monoxide Sensors with Voltage‐Activated Sensitivity." Angewandte Chemie 129 (45) ,2017, 14254. Carbon monoxide (CO) outcompetes oxygen when binding to the iron center of hemeproteins, leading to a reduction in blood oxygen level and acute poisoning. Harvesting the strong specific interaction between CO and the iron porphyrin provides a highly selective and customizable sensor. We report the development of chemiresistive sensors with voltage‐activated sensitivity for the detection of CO comprising iron porphyrin and functionalized single‐walled
