Exploring the Cobalt-Histidine Complex for Wide-Ranging Colorimetric O₂ Detection.

ABSTRACT: Developing a robust, cost-effective, and user-friendly sensor for monitoring molecular oxygen (O₂) ranging from a minute to a medically relevant level (85-100%) in a stream of flowing breathable gas is vital in various industrial domains. Here, we report an innovative application of the cobalt(l-histidine)₂ complex, a bioinspired model of O₂-carrying metalloproteins, for rapid and reliable sensing of O₂ from 0 to 100% saturation levels under realistic conditions. We have established two distinct colorimetric O₂ detection techniques, which can be executed with the use of a common smartphone camera and readily available color-detecting software. A series of spectroscopic experiments were performed to demonstrate the molecular-level alter
