A leaf-like carbon nanotube/nickel (CNT/Ni) composite nanostructure is used as the sensing membrane in an extended-gate field-effect transistor (EGFET) for the pH sensors is first developed using nanocomposite plating technique. While sensing pH within a range of 2-10, the leaf-like CNT/Ni EGFET exhibits a sensitivity of 59 mV/pH. This simple and low-cost sensing membrane can be applied in disposable biosensors.
