Abstract
Herein we report the deployment of kag-MOF as a sensing layer on a capacitive IDE sensor for detecting H2S at room temperature. Compared to other gases such as nitrogen dioxide, ammonia, carbon dioxide, and carbon monoxide, kag-MOF exhibited a unique and selective response to H2S, making it a promising candidate for H2S sensing applications. In particular, the kag-MOF layer demonstrated a particularly good response and selectivity to H2S in stimulated human breath and could detect concentrations as low as 500 ppb, even under humid conditions. These results clearly demonstrate that kag-MOF has immense potential as a candidate for H2S sensing, and its sensing behaviour opens possibilities for developing gas/vapor sensors that could potentially diagnose uremia at an early stage by monitoring H2S levels in the breath, giving it a potential application in the field of healthcare.
