چکیده:

In this paper an attempt is made to review the specific urease with one of the best and most modern materials, modifiers, in order that multi-walled carbon nanotubes (MWCNTs) / silica, which has been modified with the rest of the Biosensors are a large variety of electrodes with different genera based fixative that can work with different fixed times to examine. This is important in order to be useful for biosensor And a lot of them, sometimes we doubt that what we wrong Biosensor that is relevant to our work, we use this to help us Associated with plant conditions and at what strength and durability of stabilized We expect our biosensor, Biosensors of your choice to be taken to maximize the efficiency of its And have less time and money trying to be good and resist. The resulting biosensor exhibits a good response performance to urea detection with a wide linear range from 2.18×۱۰−۵ to 1.07×۱۰−۳ M urea. The biosensor shows a short response time of 10–۲۵ s and a high sensitivity of 23 mV /decade/ cm2 [
