“…In two-dimensional devices, the sample is deposited in the same layer in which the electrochemical cell is printed or flows toward it by capillarity. As commented before, platforms are commonly fabricated by patterning a single piece of paper with a hydrophobic material (e.g., wax or photoresist) that delimits hydrophilic microfluidic channels, areas or reservoirs [ 118 , 119 , 120 , 121 , 122 , 123 , 124 , 125 , 126 , 127 , 128 , 129 , 130 , 131 , 132 , 133 , 134 , 135 , 136 ]. Other materials such as adhesive tape can be used either as an additional stencil for printing the electrodes [ 121 , 137 ] or to delimit the area of the working electrode once the ink has been spread on a specific piece of paper [ 138 ].…”

Screen-printed technology has helped considerably to the development of portable electrochemical sensors since it provides miniaturized but robust and user-friendly electrodes. Moreover, this technology allows to obtain very versatile transducers, not only regarding their design, but also their ease of modification. Therefore, in the last decades, the use of screen-printed electrodes (SPEs) has exponentially increased, with ceramic as the main substrate. However, with the growing interest in the use of cheap and widely available materials as the basis of analytical devices, paper or other low-cost flat materials have become common substrates for SPEs. Thus, in this revision, a comprehensive overview on paper-based SPEs used for analytical proposes is provided. A great variety of designs is reported, together with several examples to illustrate the main applications.

“…Hence, modification of the electrode surfaces is essential for the sensitive detection of 8-HQ. Up to now, some materials such as polymers (electropolymerized 1-amino-2-naphthol-4-sulfonic acid [8] ), metal complexes (cobalt(II) phthalocyanine [9] ) and conductive carbon materials (multiwall carbon nanotube/Nafion composite [10] ) have been applied to modify electrode surface. The development of environmentally friendly, readily available and cheap materials are still greatly needed for the determination of 8-HQ.…”

Tannic acid (TA) as a natural plant polyphenol bearing multiple phenolic hydroxyl groups could cause considerable interactions with organic compounds. This work aims at detecting 8‐hydroxyquinoline (8‐HQ) based on poly (tannic acid) (PTA) by electropolymerization of TA on glassy carbon electrode (GCE). Owing to enhanced modified electrode surface area and interactions of PTA with 8‐HQ via hydrogen bonding and π‐π stacking, PTA/GCE exhibits electrocatalytic activity to 8‐HQ. Using Differential pulse voltammetry, PTA/GCE shows two linear plots with 8‐HQ concentrations from 0.5 to 5 μmol L−1 and 5 to 50 μmol L−1, the detection limit is 0.036 μmol L−1. The PTA modified electrode also shows great reproducibility and stability. The application of the sensor for real hair conditioner samples is demonstrated with satisfactory result.

The application of potassium bromate in the baking industry is used in most parts of the world to avert the human health compromise that characterizes bromates carcinogenic effect. Herein, various methods of its analysis, especially the electrochemical methods of bromate detection, were extensively discussed. Amperometry (AP), cyclic voltammetry (CV), square wave voltammetry (SWV), electrochemiluminescence (ECL), differential pulse voltammetry and electrochemical impedance spectroscopy (EIS) are the techniques that have been deployed for bromate detection in the last two decades, with 50%, 23%, 7.7%, 7.7%, 7.7% and 3.9% application, respectively. Despite the unique electrocatalytic activity of metal phthalocyanine (MP) and carbon quantum dots (CQDs), only few sensors based on MP and CQDs are available compared to the conducting polymers, carbon nanotubes (CNTs), metal (oxide) and graphene-based sensors. This review emboldens the underutilization of CQDs and metal phthalocyanines as sensing materials and briefly discusses the future perspective on MP and CQDs application in bromate detection via EIS.
