Co, Fe Dual-Doped MoS2 Nanosheets on Polypyrrole Microtubes as Effective Peroxidase Mimics for Glutathione Sensing

“…The isotherm curve indicated the mesoporous structure of Fe, Co−MoS 2 @PPy, which is beneficial for ion diffusion and mass transport, thereby improving the catalytic efficiency. 30,31 All of the results illustrated the successful synthesis of Fe, Co−MoS 2 @PPy composites with the mesoporous tubular structure integrated with Fe, Co dualdoped MoS 2 moieties. The unique rod-like structure with hierarchical MoS 2 NSs makes the Fe, Co−MoS 2 @PPy composites have great potential for catalysis and adsorption applications.…”

Fabrication of shish-kebab structure of MnO2@Co3O4 with remarkably enhanced oxidase-mimicking activity for the detection of l-cysteine

“…The two other peaks at 473 and 680 cm −1 observed for MnO 2 @Co 3 O 4 can be assigned to the Raman vibrational modes of Co–O and Mn–O, respectively. 25 Furthermore, the obtained MnO 2 @Co 3 O 4 showed type IV isotherms, suggesting its mesoporous structure 26 (Fig. 2F).…”

Simultaneous Assay of CA 72-4, CA 19-9, CEA and CA 125 in Biological Samples Using Needle Three-Dimensional Stochastic Microsensors

“…In comparison to other tools and methods proposed to date (including an ultrasensitive electrochemical immune sensor proposed for the assay of CA 72-4 by Yan et al [47]; an electrochemical sensor proposed for the simultaneous assay of CA19-9 and CA 72-4, which was based on tumor marker dual recognition via glycosyl imprinting and lectin-specific binding, proposed by Luo et al [48]; an ultrasensitive split-type electrochemical immunosensor based on the controlled-released strategy proposed by Li et al for the assay of CA 19-9 [49]; a photoelectrochemical immunosensor proposed by Gholamin et al for the assay of CA 19-9 [50]; a flower-shaped chemiluminescence-based sensor for the assay of CEA [51]; a magnetic copper silicate and boronic acid conjugate AuNCs@keratin-based electrochemical/fluorescent dual sensor proposed by Jin et al for the determination of CEA [52]; for the assay of CA 125, a hydrogel-based immunosensor proposed by Er et al [53]; and a label-free dual immunosensor proposed by Kamac et al [54]), the needle 3D stochastic microsensors proposed in this paper had the following advantages: The developed sensors exhibit reliable molecular recognition capabilities for CA 72-4, CA 19-9, CEA and CA 125, and they demonstrate wider working concentration ranges compared to those documented in the referenced papers. Additionally, the sensors achieve lower limits of determination and higher sensitivities, and their design, which does not involve the use of biomolecules, contributes to their enhanced stability over time.…”
