Ionomer-Based Ion-Sensitive Field-Effect Transistor for Lithium Ion Sensing
Lithium detection is critical in the medical field, as it is used for the treatment of bipolar disorder. Here, we offer a simple method using an ion-sensitive field-effect transistor device prepared to detect the presence of lithium in a solution. The Nafion 115 membrane used in this study has been conditioned to allow the transport of lithium ions from the electrolyte to a zinc oxide-based transistor. The device was studied with lithium ion concentrations ranging between 10<sup>-2</sup>-10<sup>-7</sup> M. It was modeled using the COMSOL Multiphysics program for 10<sup>-2</sup> M. The device showed 2.85 mA/decade sensitivity and a detection limit of 77 μM.
