英文摘要	Currently, nanomaterial-based all-solid-state ion-selective electrodes (ASS-ISEs) have become attractive tools for ion sensing in environmental and biological applications. However, nanomaterial solid contact can easily fall off the electrode surface owing to poor adhesion. This poses serious limits to the wide use of these sensors. Herein, we report a general and facile method for the robust fabrication of nanomaterial-based ASS-ISEs. It is based on the silver-based conductive adhesive (CA) with excellent electronic conductivity and strong adhesion ability as the binder to construct nanomaterial-based solid contact. The solid-contact Ca2+-ISE based on single-walled carbon nanotubes (SWCNTs) is chosen as a model. The proposed electrode based on CA-SWCNTs shows a linear response in the concentration range of 10 6 to 10 3 M with a slope of 25.96 0.36 mV per decade and a detection limit of 1.7 10 7 M. In addition, the CA-SWCNT-based Ca2+-ISE exhibits an improved potential stability and reduced water film compared to the coated-wire ISE. Above all, experiments also show that the CA-SWCNTbased electrode exhibits nearly the same electrochemical characteristics as the classical only SWCNTbased electrode in term of resistance, capacitance and potential stability. We believe that CAnanomaterial- based solid contacts provide an appealing substitute for traditional solid contacts based on nanomaterials.
