“…The results of potentiometric detection could be affected by nonbuffered media with low ionic strength especially for low metal concentrations. Meanwhile the conclusion about rather low sensitivity of the detection of alkali and alkaliearth metal ions with the PANI based sensor was confirmed by similar experiments previously performed in the presence of Na 2 SO 4 and nitric acid (pH 1.7) [9,33].…”

A novel potentiometric sensor based on screen‐printed carbon electrode covered with electropolymerized polyaniline (PANI) and unsubstituted pillar[5]arene as ionophore has been developed and tested in potentiometric measurements of pH and metal ions. The introduction of pillar[5]arene improved the reversibility of the pH response in the range from 2.0 to 9.0 with the slope of 45 mV/pH. Among metal cations, the response to Fe3+ and Ag+ ions was referred to PANI redox conversion whereas the signal toward Cu2+ in the range from 1.0×10−6 to 1.0×10−2 M (limit of detection (LOD) 3.0×10−7 M) to specific interaction with the macrocycle.

“…As it was shown using dynamic light scattering, picrate extraction and potentiometry, thiacalixarenes interact with Ag + ions to form nanoaggregates that are stable in solution and on the interface [36][37][38]. In this paper, we report a simple and effective way of the simultaneous synthesis and stabilization of the silver nanoparticles by the thiacalix [4]arene derivative bearing catechol terminal groups at the lower rim.…”

A sensitive electrochemical sensor based on a composite containing silver nanoparticles and a redox active thiacalixarene with catechol fragments in the substituents at the lower rim has been developed and used for dopamine detection. The electrochemical investigation of thiacalixarene in homogeneous solution and on the electrode interface showed the reversible character of the redox conversion of catechol fragments and its involvement in the chemical reduction of silver which resulted in formation of uniform nanoparticles of 4-6 nm in diameter. The use of such a material for electrode modification made it possible to record a high amplitude cathodic signal at À700 mV that was proportional to the dopamine concentration within 1 nM-1 mM. (limit of detection 0.5 nM).

“…In particular, polyaniline membranes are rarely if ever used for detection of Ag + ions. Recently Evtugyn et al [18,19] fabricated polyaniline and thiacalix [4]arene derivatized composite membranes on glassy carbon and employed the sensors for potentiometric determination of Ag + . The modified electrodes were obtained by initially depositing polyaniline using electropolymerization, and subsequently placing thiacalix [4]arene onto the electrode.…”
