“…A smart strategy to overcome this situation is the immobilization of the complexes in a composite. Carbonbased nanomaterials such as graphene, reduced graphene oxide (RGO), graphene oxide (GO), or carbon nanotubes (CNTs) are widely used to immobilize MP or MPc via the π-π non-covalent stacking interactions that occur between porphyrin rings and the nanomaterial's aromatic rings [7]. This kind of combination enhances the electron-conductive properties of coordination complexes and makes MP and MPc very stable compounds in alkaline or acidic media [8].…”

“…As an alternative analytical tool, diverse electrochemical sensors based on coordination compounds have been developed for the identification and quantification of these pollutants in aqueous media. Cobalt (II) and iron (III) phthalocyanine or porphyrin composites are widely preferred as redox-active catalysts on this kind of electrochemical sensor due to their high efficiency in electro-oxidation reactions in acidic media, their high surface area, and the presence of high electron density on their 18 π-electron aromatic ring that make these molecules perfectly suitable for being robust electron mediators [7]. Excellent results have been obtained with these composites, presenting LOD from femtomolar to micromolar order.…”

Metalloporphyrins (MP) and metallophtalocyanines (MPc) are innovative materials with catalytic properties that have attracted attention for their application for diverse electrochemical purposes. The presence of metallic centers in their structure offers a redox-active behavior that is being applied in the design of solid electrodes for the quantification of biomolecules, water contaminants, and pharmaceuticals, among others. Herein, we collect the recent information about porphyrin and phthalocyanine complexes as modifiers of electrodes, and the important aspects of the design, characterization, and application of these electrodes.

“…Other self-assembly methods have been proposed to develop sensors based on GO and Fe(III) or Cu(II)-metalloporphyrins to detect bisphenol A or dopamine. [167,168] In another study, FeTMAP was self-assembled onto rGO, yielding FePGF, which was further applied in electrocatalysis ( Figure 10). [169] In this case, it was reported that the frameworks were formed rapidly and agglomerated in the solution, while the residual solution became colorless, suggesting the formation of larger and heavier agglomerates.…”

Among the available carbon nanomaterials, graphene oxide (GO) has been widely studied because of the possibility of anchoring different chemical species for a large number of applications, including those requiring water‐compatible systems. This Review summarizes the state‐of‐the‐art of synthetic routes used to functionalize GO, such as those involving multiple covalent and non‐covalent bonds to organic molecules, functionalization with nanoparticles and doping. As a recent development in this field, special focus is given to the formation of nanocomposites comprising GO and porphyrins, and their characterization through spectroscopic techniques (such as UV‐Vis, fluorescence, Raman spectroscopy), among others. The potential of such hybrid systems in targeted biological applications is also discussed, namely for cancer therapies relying on photodynamic and photothermal therapies and for the inhibition of telomerase enzyme. Lastly, some promising alternative materials to GO are presented to overcome current challenges of GO‐based research and to inspire future research directions in this field.

“…Recently, Hsine et al [ 56 ] combined the use of a porphyrin derivative with that of thermally reduced graphene oxide (TRGO), which also can be attached using π–π interactions. BPA molecules were absorbed on the surface of the nanocomposite, increasing the membrane resistance, which was quantified with EIS.…”

Endocrine disruptors (EDs) are contaminants that may mimic or interfere with the body’s hormones, hampering the normal functions of the endocrine system in humans and animals. These substances, either natural or man-made, are involved in development, breeding, and immunity, causing a wide range of diseases and disorders. The traditional detection methods such as enzyme linked immunosorbent assay (ELISA) and chromatography are still the golden techniques for EDs detection due to their high sensitivity, robustness, and accuracy. Nevertheless, they have the disadvantage of being expensive and time-consuming, requiring bulky equipment or skilled personnel. On the other hand, early stage detection of EDs on-the-field requires portable devices fulfilling the Affordable, Sensitive, Specific, User-friendly, Rapid and Robust, Equipment free, Deliverable to end users (ASSURED) norms. Electrochemical impedance spectroscopy (EIS)-based sensors can be easily implemented in fully automated, sample-to-answer devices by integrating electrodes in microfluidic chips. The latest achievements on EIS-based sensors are discussed and critically assessed.
