Electrochemistry at the interface between two immiscible electrolyte solutions (ITIES) has become an invaluable tool for the selective and sensitive detection of cationic and anionic species, including charged drug molecules and proteins. In addition, neutral molecules can also be detected at the ITIES via enzymatic reactions. This chapter highlights recent developments towards creating a wide spectrum of sensing platforms involving ion transfer across the ITIES. As well as outlining the basic principles needed for performing these sensing applications, the development of ITIES-based detection strategies for inorganic, organic, and biological ions is discussed.

The stabilization of lecithin layer physically adsorbed on the interface between two immiscible electrolyte solutions (ITIES) using addition of Yb3+ to the aqueous phase was studied using cyclic voltammetry. Stability of this layer was evaluated according to the time of the layer formation; the optimal time amounted to 180 s. The stability of the layer as a function of the potential applied on the system during the layer formation was investigated. The behavior of the monolayer during the layer polarization was studied by the facilitated K+ transport using dibenzo-18-crown-6. The stoichiometry of Yb/anion/lecithin complexes was investigated using electrospray ionization mass spectrometry (ESI-MS).

En este trabajo se estudió la influencia del lípido L-α-fosfatidilcolina en la transferencia de los cationes TMA+ y TEA+ a través de la interfase formada entre dos líquidos inmiscibles. En un sistema electroquímico basado en una celda de cuatro electrodos, se aplicaron las técnicas de voltamperometría cíclica y espectroscopía de impedancia electroquímica. Se determinaron los potenciales de onda media de ambos cationes, mismos que se compararon con valores previamente publicados sin la presencia del lípido; también se estudió la cinética de transferencia con la interfase modificada y sin modificar. En base a estos experimentos, se encontró que la monocapa formada por las diferentes concentraciones (10-30 mM) de PC causa un efecto en el desfasamiento del potencial de transferencia a valores menos positivos, con lo cual se deduce que una barrera más hidrofóbica induce un efecto en el cambio de la energía de transferencia de estos cationes. Por otro lado, la monocapa del lípido disminuye la constante de velocidad de transferencia en función de la concentración de éste.
