Recent advances in ion sensing with
Ion interactions with conducting polymers. The mechanism and behaviour of the oxidation and reduction in conducting polymers, has an influence on the polymer’s utility in sensing. To this end, research into the doping process is of interest that accompanies the oxidation or reduction of the polymer.
The New Lead (II) Ion Selective Electrode Based On Free
Sensor selectivity test is on of the important parameter to be done in the development of ion-selective electrode (ISE) types such as Pb 2+-ISE. Selectivity test describes the ability of sensor to respond to the target analyte without influence of presence of contaminant ions. 16 , 17 This test aims to assess the Pb 2+ -ISE sensor's performance

- What are Plasticizer-based and polymer-free ion-selective optodes?
- Plasticizer-based and polymer-free ion-selective optodes are fabricated on cellulose paper. The use of plasticizers enhances the optode performance compared to plasticizer-free optodes. Inkjet printing of the plasticizer-based optode ink is realized using the newly launched Samba cartridge.
- Which ionophore is most compatible with plasticizer-free optodes?
- An ionophore with a solvation capability is most compatible with the concept of plasticizer-free optodes. For other solid ionophores with rigid structures, the inclusion of a plasticizer significantly enhances the sensitivity of the ISOs. 3.3. Inkjet printing of paper-based ISOs using tetrahydrofuran-based inks with plasticizers
- Do plasticizer-free paper-based ionophores behave like Plasticizer based optodes?
- It is clear that the plasticizer-free paper-based ISOs do not automatically behave identically to their plasticizer-based counterparts. An ionophore with a solvation capability is most compatible with the concept of plasticizer-free optodes.
- What are ionophores and auxiliary components used in potentiometric or optical sensors?
- Ionophores and auxiliary components (polymers, plasticizers, additives) used in potentiometric or optical sensors have different specifications than materials used for other applications. It is essential that the product is free of disrupting impurities, such as metal ions or surfactants.
- What is a plasticizer based ionophore?
- The plasticizer provides a low-polarity solvent environment that is independent of the ionophore used. The plasticizer-based and polymer-free ISOs allow for accurate colorimetric measurements of urine calcium in an example application.
- Are plasticizers better than plasticizer-free optodes?
- The use of plasticizers enhances the optode performance compared to plasticizer-free optodes. Inkjet printing of the plasticizer-based optode ink is realized using the newly launched Samba cartridge. The inkjet-printed optodes are used for colorimetric calcium measurements in urine.
