“…The greatest electrochemical performance was achieved with multiwalled carbon nanotubes based screen printed electrodes (aSPCNTE/PAA:Pt) with a limit of detection in the range of 24-558 nM with no interference among all carbon-based composites tested. 48 Graphene is a two-dimensional monolayer sheet made up of sp 2 bonded carbon atoms organized in a hexagonal lattice. The key advantages of employing graphene as a modifying material to develop SPE are its unique properties of large surface area, excellent electron transfer rate, and high mechanical strength.…”

Portability is one of the essential keys in the development of modern analytical devices. Screen printing technology is an established technology for both chemical and biosensor development. Screen printing technology has been used to generate a variety of electronic sensors that are rapid, cost-effective, on-site, real-time, inexpensive, and practical for use in healthcare, environmental monitoring, industrial monitoring, and agricultural monitoring. This review aims to describe recent research progress related to the development and improvement of screen-printed electrodes (SPEs). We also demonstrate the wide range of applications, also highlighting the market directions and the need for novel devices to be used by non-specialists. Finally, we conclude and provide an overview of the constraints and future opportunities of SPEs in biosensor application.

Cumene hydroperoxide (CHP) is an important initiator in polymerization industry. The compound is potentially explosive, toxic, and mutagenic. Herein, an electrochemical sensor is developed for CHP detection. First, the mechanism of CHP electrode process was investigated by a combination of electrochemical methods and ex-situ characterization techniques (SEM, FTIR, LC-MS, 1H-NMR, and 13C-NMR). The electrochemically generated species became more easily reduced than CHP and deposited on the electrode surface, allowing the analyte to be detected at low overpotential in aqueous solutions (as opposed to organic solvents typically needed in organic peroxide detection). In addition to the newly developed method, the performance of the electrochemical sensor was further enhanced via the use of copper hexacyanoferrate (CuHCF), a Prussian blue analogue which showed strong electrocatalytic activity towards peroxide reduction. A number of different CuHCF samples were synthesized and tested. The crystalline nanostructured CuHCF with high surface area (31.92 m2 g−1) and large lattice parameter (10.1397(1) Å) yielded excellent analytical performance towards CHP detection. The optimized method showed high tolerance to interferences and was validated in tap water samples. The excellent reproducibility (%RSD = 1.81, n = 3), high sensitivity (44.03 μA cm−2 mM−1), and low detection limit (5.9 μM, 3S b/m) of the developed CHP sensor were demonstrated.
