Dear fellow researchers, I am curious about spin-coatable ion detectable membrane for Ca2+. What composition would be best if I use graphene FET for detection. What would be the spin coating code for obtaining precise thickness?
For metal evaporation, cost of Au and Pd pallets are comparable. But in most of the cases, Au electrode is widely used though the work function of graphene under Au is lower than graphene under...
