Abstract: The present invention provides a method and system for applying ion-selective membrane on Ion-Sensitive Field Effect Transistor (ISFET) surface without involving a mask step. In one embodiment multi-purpose ISFET devices are first prepared at wafer level using a standard Complementary Metal Oxide Semiconductor (CMOS) fabrication process up to Metal I bond pad and ISFET gate window is open for ion sensing purposes. A retaining structure is applied 105 as a protective layer and to define the gate window opening prior to membrane cocktail application 107 by manually pipetting out through a pipette.

Abstract: The present invention relates to preparation of chemical sensor membrane in the absence of assistance from any plasticizer, and using immobilized fluorinated lipophilic tetraphenylborate salts for in situ measurement of cations soil macronutrients and environmental monitoring of organic cation contaminants. The sterically shielded tetraphenylborate salt covalently bonds to acrylic polymer backbone and creates lipophilic anionic sites that are loosely bound to cations.
