Electronic tongue systems are multisensor devices dedicated to automatic analysis of complicated composition samples and to the recognition of their characteristic properties. Recently, the number of publications covering this topic has significantly increased. Many possible architectures of such devices were proposed: potentiometric, voltammetric, as well as approaches embracing mass- and opti...

Manganese plays a key role in the health of human beings therefore, its determination is very important in medical fields. In this regards, a novel coated graphite electrode was constructed for determination of manganese (II) by using zolpidem as an ionophore, for the first time. The best performance was obtained of the membrane composition of PVC (32%), Potassium tetrakis (4-chlorophenyl) bora...

A new selectophore was introduced for Cu2+ ions. Spectroscopic studies showed a selectivity of a new organic compound (L) toward copper ions and several transitional metal ions. Hence, L was utilized in designing several ion selective electrodes for these cations. In practice, Cu2+ ion selective electrode behaved Nernstian (slope of 27.95±0.3 mV decade-1) over a...

We built an integrated solid-contact ion-selective electrode (SCISE) system with the functionality of self-calibration. A multiplexed SCISE sensor (K+ and NO3− vs. Ag/AgCl) was fabricated on printed-circuit board (PCB) substrates subsequently embedded into a microfluidic flow cell for self-calibration flow-through analysis. PCB circuit that includes modules both readout fluid control developed....
