Organophosphonic acid and cerium functionalized antimonotungstate with electrochemical promise in biosensing bacterial dissimilatory sulfite reductase gene sequence

Abstract

Rational design and synthesis of organically functionalized cluster-based materials has always been one of the hot topics. Polyoxometalates (POMs) have become primary candidates for fabricating novel organic−inorganic hybrid cluster-based materials...

Cerium-Encapsulated SbIII–SeIV-Templating Polyoxotungstate for Electrochemically Sensing Human Multidrug Resistance Gene Segment

“…Besides, two rGO materials were, respectively, fabricated with and without addition of 1 (the former is marked as 1 @rGO, while the latter is marked as p-rGO; SEM images of 1@rGO are shown in Figure S21) under the same conditions to preparing 1 -Au@rGO. As illustrated in Figure b, only the characteristic peak of rGO (2θ = 27.9°) is observed in the PXRD pattern of 1 @rGO, demonstrating the reduction of GO to rGO, while characteristic peaks of both GO (2θ = 12.7°) and rGO occur in the PXRD pattern of p-rGO, illustrating that the reduction of GO is incomplete . That is to say, the addition of 1 in the reaction can enhance the efficiency of the N 2 H 4 reduction of GO .…”

“…As illustrated in Figure 4b, only the characteristic peak of rGO (2θ = 27.9°) is observed in the PXRD pattern of 1@rGO, demonstrating the reduction of GO to rGO, while characteristic peaks of both GO (2θ = 12.7°) and rGO occur in the PXRD pattern of p-rGO, illustrating that the reduction of GO is incomplete. 54 That is to say, the addition of 1 in the reaction can enhance the efficiency of the N 2 H 4 reduction of GO. 55 This observation can be also verified by Raman spectra (Figure 4c).…”

Advances in polyoxometalate-based electrochemical sensors in the last three years

“…93 Besides, a binary composite 14/CMCN was prepared by combining 14 and carboxylated multiwalled carbon nanotubes (CMCN). The 55 This journal is © The Royal Society of Chemistry 2024 (PW12)-based electrochemiluminescence (ECL) immunosensor for protein detection by the quenching of PW12 on ECL emission of luminol loaded CeVO 4 /Au (Fig. 4d).…”

“…In the same year, the POM-based ECS for bacterial dissimilatory sulte reductase gene sequence detection was put out by this group. 55 16) as the POM unit, an Au-rGO-16 nanocomposite was fabricated as an electrochemically active material in this work (Fig. 4h).…”

Two new manganese-based phosphomolybdate compounds as electrochemical sensors for the highly sensitive trace determination of heavy metal Cr(vi) ions

“…Polyoxometalates (POMs) have attracted extensive attention in optics, electricity, pharmaceuticals, and materials science due to their definite structure, adjustable composition, and various unique physical and electrochemical properties. 16–25 Also, POMs are ideal candidates for electrochemical sensor materials due to their unique electrochemical redox properties. 26–29 In particular, as a member of POMs, the P 4 Mo 6 V O 31 12− cluster (abbr.…”
