ABSTRACT:
The present invention provides an ammonia sensor including a pH sensitive fluorophore immobilized in a hydrophobic polymer, wherein the fluorophore can react quantitatively with ammonia and the transducing moiety of the fluorophore is neutrally charged when deprotonated. The present invention also provides a method for detecting ammonia using the ammonia sensor and optical sensing devices comprising the ammonia sensor.
