“…If the glucose sensors and some other electrochemical biosensors are now established among the commercially successful technologies [10][11][12] and if wearable and/or skin electrochemical sensors appear to be very promising for economically viable applications [13][14][15], there are still a lot of room for improvement. Nanomaterials have proven to be suitable candidates contributing to the evolvement of electrochemical sensing platforms and hundreds of reviews are available dealing with the use of various kinds of electrode modifiers, such as nanoparticles, 2D layered nanomaterials or 3D nanostructures owing to their electrocatalytic response and/or recognition capabilities (see some illustrative examples [16][17][18][19][20][21]). However, the focus of many studies is targeted towards feasibility demonstration, association of multiple nanomaterials for signal amplification, determination of analytical figures of merit and comparing systems between them, etc.…”

The interaction of drugs with DNA has been searched thoroughly giving rise to an endless number of findings of undoubted importance, such as a prompt alert to harmful substances, ability to explain most of the biological mechanisms, or provision of important clues in targeted development of novel chemotherapeutics. The existence of some drugs that induce oxidative damage is an increasing point of concern as they can cause cellular death, aging, and are closely related to the development of many diseases. Because of a direct correlation between the response, strength/ nature of the interaction and the pharmaceutical action of DNA‐targeted drugs, the electrochemical analysis is based on the signals of DNA before and after the interaction with the DNA‐targeted drug. Nowadays, nanoscale materials are used extensively for offering fascinating characteristics that can be used in designing new strategies for drug‐DNA interaction detection. This work presents a review of nanomaterials (NMs) for the study of drug‐nucleic acid interaction. We summarize types of drug‐DNA interactions, electroanalytical techniques for evidencing these interactions and quantification of drug and/or DNA monitoring.

Modular sensor platforms are a fashion approach that allows the use of advanced materials to promote the evolution of portable electrochemical sensors. A modular platform building by the combination of carbonized poly(acrylonitrile) electrospun mat (C‐PAN; fiber diameter ca. 300 nm) and a poly(N‐isopropylacrylamide; PNIPAm) hydrogel was assayed. The individual components of the platform were physicochemically characterized before assembling. The swelling behavior and the capacity of sorption of a redox complex tris(1,10‐phenanthroline)iron(II) of the polymeric hydrogel were evaluated. Moreover, the morphological aspects of the electrospun fibers before and after carbonization were analyzed. Finally, cyclic voltammetry and chronocoulometry experiments were performed to analyze the electrochemical performance of the modular platform. In this work, we demonstrated that the platform takes advantage of the3D structure of the electrospun mat and the selective sorption of the hydrogel for the electrochemical sensing target analyte. The iron sensing using its complexation into the tris(1,10‐phenanthroline)iron(II) redox complex was assessed by differential pulse voltammetry (DPV). The anodic peak current showed a linear relation versus iron complex concentration in the range of 10–80 μmol L−1 with a detection limit of 0.103 μmol L−1. All the results herein presented suggest that a synergistic combination of large surface area carbon fiber electrodes and ion retaining hydrogel has been achieved.
