摘要：

The developed potentiometric urea biosensor is based on a modified PVC-nonactin NH3-sensitive gas electrode. Membrane resistance has been optimised by incorporating lipophilic salt. The coefficient of variation for the standard urea solution is 2.45. The sensor performance has been compared with a photometric method for blood samples.
