“…In our experience, it is a very efficient tool to analyze the interaction of various compounds with functionalized surfaces. [30,31] For further characterization, EIS was performed to evaluate the proposed system after the interaction with lead (II). Measurements were performed in KCl 0.1 m at pH 7 after incubation in lead (II) solutions at the open circuit potential (OCP).…”

This work presents a study of self‐assembled platforms of polyelectrolytes constructed by drop casting on screen‐printed electrodes for lead (II) sensing. Infrared characterization by attenuated total reflection (ATR) and electrochemical impedance spectroscopy (EIS) were carried out to evaluate the modification of the surface, its stability against treatment and the changes induced by the adsorption of lead cations. An equivalent circuit of the type R1 [R2 CPE1] CPE2 that explained the results for the actual surface modification was obtained. Linear correlations with lead concentration in the range of 0.5–2.5 mm were found by differential pulse voltammetry (DPV) and EIS techniques for solutions at pH 3. There was a particular concentration in which the presence of citrate increased the DPV reduction signal of lead while ethylenediaminetetraacetic acid (EDTA) diminished it.

The development of sensing coatings, as important sensor elements that integrate functionality, simplicity, chemical stability, and physical stability, has been shown to play a major role in electrochemical sensing system development trends. Simple and versatile assembling procedures and scalability make polyelectrolytes highly convenient for use in electrochemical sensing applications. Polyelectrolytes are mainly used in electrochemical sensor architectures for entrapping (incorporation, immobilization, etc.) various materials into sensing layers. These materials can often increase sensitivity, selectivity, and electronic communications with the electrode substrate, and they can mediate electron transfer between an analyte and transducer. Analytical performance can be significantly improved by the synergistic effect of materials (sensing material, transducer, and mediator) present in these composites. As most reported methods for the preparation of polyelectrolyte-based sensing layers are layer-by-layer and casting/coating methods, this review focuses on the use of the latter methods in the development of electrochemical sensors within the last decade. In contrast to many reviews related to electrochemical sensors that feature polyelectrolytes, this review is focused on architectures of sensing layers and the role of polyelectrolytes in the development of sensing systems. Additionally, the role of polyelectrolytes in the preparation and modification of various nanoparticles, nanoprobes, reporter probes, nanobeads, etc. that are used in electrochemical sensing systems is also reviewed.
