Development of Long Term Stable Multiple-Ion- Selective Sensors for Agriculture and Aquaculture applications

An integrated multiplex all-solid-state, polymer membrane-based ion-selective-electrode was designed and fabricated. The device includes an on-chip Pt pseudo-reference electrode and three independent Au working electrode. Nitrate, potassium, and phosphate selective membranes are coated on three elec...

Description
Summary:An integrated multiplex all-solid-state, polymer membrane-based ion-selective-electrode was designed and fabricated. The device includes an on-chip Pt pseudo-reference electrode and three independent Au working electrode. Nitrate, potassium, and phosphate selective membranes are coated on three electrodes independently. The sensitivity, selectivity, and stability of the device are evaluated using a laboratory-made measurement circuit board for ion concentrations from 10 μM to 100 mM.
