A plasmophore sensitized optode was developed for imaging ammonia (NH3) concentrations in muscle tissues. The developed ammonia sensor and an equivalent non plasmophore version of the sensor were tested side by side to compare their limit of detection, dynamic range, reversibility and overall imaging quality. Bio-degradation patterns of ammonia release from lean porcine skeletal muscle were studied over a period of 11 days. We demonstrate that ammonia concentrations ranging from 10nM can be quantified reversibly with an optical resolution of 127μm in a sample area of 25×35mm. The plasmophore ammonia optode showed improved reversibility, less false pixels and a 2nM...
Highlights: ► A plasmophore sensitized optode for imaging ammonia (NH3) concentrations in muscle tissues was developed. ► Ammonia concentrations ranging from 10nM and upwards can be quantified reversibly with an optical resolution of 127μm. ► The general sensing scheme offers new possibilities for the development of artificial optical noses and tongues.
