A novel Keggin‐type metatungstate hybrid POMs ((APy)6[H2W12O40])/carboxylic acid functionalized single‐walled carbon nanotube based amperometric sensing platform was successfully constructed for the sensitive detection of hydrogen peroxide. A simple and reliable procedure was implemented for the synthesis of new composite materials obtained by the covalent grafting of (APy)6[H2W12O40] onto the surface of (SWCNT‐COOH). The synergistic effect of single walled carbon nanotubes on the electrochemical behavior of (APy)6[H2W12O40] was evidenced through the increase of the oxidation and reduction peaks of the polyoxometalate. The sensitivity of hydrogen peroxide detection was increased by a factor of 38.5 in presence of SWCNTs, showing their high influence on peroxidase‐like mimics of (APy)6[H2W12O40]. The detection limit, the response time, the repeatability and the shelf lifetime were respectively 0.4 μM, 10 s, <4%, 60 days.

“…It should be noted that one of the new orientations in the development of POM-based materials is the use of the electrochemical ability of POMs to construct electrochemical sensors. Therefore, a new exploration tendency has been established with remarkable abilities like high sensitivity, selectivity, and low limit of detection of glucose sensor applications obtained by using POM-based electrode materials. − The first use of POMs with the ability for glucose sensing was reported by Turdean et al They designed and developed an amperometric glucose sensor based on trilacunary Keggin-type POM deposited on a graphite electrode . In addition, Xu et al reported a novel nonenzymatic glucose electrochemical sensor based on Cu NPs and PMo 12 -functionalized graphene.…”

We exploited a tactic to obtain a low-cost, highefficiency, pollution-free, and stable nonenzymatic polyoxometalatebased heterogeneous electrode material for electrochemical sensing of glucose. It is first followed by the countercation exchange of K 2 Na 8 [Cu 4 (H 2 O) 2 (PW 9 O 34 ) 2 ] (CuPOM) using cesium chloride to prepare an insoluble CuPOM (Cs-CuPOM), which exhibits a uniform and perfect claviform shape with smooth surface. Further, it was mixed with graphite powder to prepare Cs-CuPOM-modified carbon paste electrode (Cs-CuPOM/CPE) with the Cs-CuPOM content between 15% and 50% in weight. This obtained electrode material Cs-CuPOM shows a better electrochemical sensor activity than Cs-MnPOM, Cs-FePOM, and other reported POM-based electrode materials for glucose oxidation on account of their quicker electron transfer kinetics, which also exhibits conspicuous characteristics with a wide linear range of 5−1500 μM. It also possesses a high sensitivity of 16.3 A M −1 cm −2 and a low limit of detection (LOD) of 0.99 × 10 −6 M at the signal-to-noise ratio of 3. The conspicuous sensing feature, low cost, and liable synthetic method can make Cs-CuPOM a promising candidate for the exploitation of a preeminent glucose sensor.

Two new inorganic-organic hybrid materials based on heteropolyoxometalates (POMs): (CHN)[PMoO]·4HO (PMo) and (CHNO)[HPWO]·6HO (PW) are reported as mediators for electron transfer between FAD-dependent glucose dehydrogenase (FAD-GDH) and a multiwalled carbon nanotube (MWCNT) matrix for glucose biofuel cell and biosensor applications. These polyoxometalates were chosen due to their promising redox behavior in a potential range for mediated electron transfer with the glucose oxidizing enzyme, FAD-GDH. PMo and PW were immobilized on 1-pyrenemethylamine (PMA) functionalized MWCNT deposits. After immobilization of FAD-GDH, the PW-modified MWCNT electrode demonstrated mediated electron transfer and provided a catalytic current density of 0.34 mA cm at 0.2 V vs SCE with an open circuit potential (OCP) of -0.08 V vs SCE. A 10-fold increase in catalytic current to 4.7 mA cm at 0.2 V vs SCE and a slightly lower OCP of -0.10 V vs SCE was observed for an equivalent electrode modified with PMo.The apparent superiority of PMo is related, at least in part, to its improved incorporation in the MWCNT matrix compared to PW. Both POM-modified bioanodes showed exceptional stabilities with 45% of their initial performances remaining after 15 days. The mediated electron transfer capacities of the POMs were also evaluated in a glucose sensor setup and showed very satisfying performances for glucose detection, including a sensitivity of 0.198 mA mol L cm, a satisfying linear range between 1 mmol L and 20 mmol L, and good reproducibility for the PMo electrode.
