Fluorescent polymeric sensor for the detection of urea |
| abstract |
The present invention provides a urea sensor material having a first layer of a protonated 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; a second layer of urease and a polymer; and a third layer of a polymer. The present invention also provides a method for detecting urea using the urea sensor material and optical sensing devices that incorporate the urea sensor material. |
