I have a sensor with Ni nanoparticles on reduced graphene oxide for glycerol determination and need to calculate the thickness of the sensing membrane...
Is there any way to calculate based on theory or do I need to perform a TEM?
If the sensing layer (membrane) is attached to the electrode, you can use a thickness gauge to measure the thickness of the layer. First, measure the thickness with membrane and then without membrane, you will get the thickness size.
