“…Yazhini et al used MWCNTs mixed with pectin to prepare the working electrode due to the high surface area and specific orientation, which provides more binding sites with pectin through OH bonds. 64 Kalaivani et al fabricated an electrode with a MWCNT/inulin–TiO 2 composite, with limits of detection of 0.06 and 90 μM and concentration ranges of 0.2–1 and 50–12 000 μM. 41 Inulin and TiO 2 were mixed to form a biocomposite by Lewis's acid–base interactions.…”

In this work, the bimetallic (Ni,Co) sulfide film of 852.213 nm thickness was successfully deposited using the spray pyrolysis technique at 300 °C. The compound was prepared with a mixture of nickel acetate (C4H6O4Ni. 4H2O), cobalt chloride (CoCl2. 6H2O), and thiourea (CS(NH2)2) as precursors for Ni, Co, and S, respectively. The temperature and sedimentation time were 300 °C and 10 min, respectively; the film was then, characterized without any thermal post-treatment. The structural, morphological, optical and electrical analysis were carried out to investigate the different properties of the material. The X-ray diffraction analysis confirmed the presence of NiCo2S4 according to the JCPDS Card # 98- 004-0019, with an average crystallite size of 34.45 nm. The optical analysis revealed the metallic behavior of the film with an average transmittance of 3.41% in the visible region and a direct optical band gap of 2.15 eV, as well as a high absorption coefficient of α ≈ 104 - 105 cm-1 ). The elementary composition analysis (EDS) confirmed the presence of Ni, Co and S elements in the film. Morphological analysis revealed a homogeneous, compact, crack-free appearance and a granular surface in all studied areas. On the other hand, the film shows a high electrical conductivity of about 1.42×105 S/cm at room temperature. The obtained results show that the bimetallic (Ni, Co) sulfide prepared in this study exhibits a good crystallinity, dense morphology, good stoichiometric ratio and high conductivity. Therefore, it is a potential candidate for application in supercapacitors as electrode material.

Biopolymers are an attractive green alternative to conventional polymers, owing to their excellent biocompatibility and biodegradability. However, their amorphous and nonconductive nature limits their potential as active biosensor material/substrate. To enhance their bio-analytical performance, biopolymers are combined with conductive materials to improve their physical and chemical characteristics. We review the main advances in the field of electrochemical biosensors, specifically the structure, approach, and application of biopolymers, as well as their conjugation with conductive nanomaterials, polymers, and metal oxides in green-based non-invasive analytical biosensors. In addition, we reviewed signal measurement, substrate bio-functionality, biochemical reaction, sensitivity, and limit of detection (LOD) of different biopolymers on various transducers.To date, pectin biopolymer, when conjugated with either gold nanoparticles, polypyrrole, reduced graphene oxide, or multiwall carbon nanotubes forming nanocomposites on glass carbon electrode transducer, tends to give the best LOD, highest sensitivity, and can detect multiple analytes/targets. This review will spur new possibilities for the use of biosensors for medical diagnostic tests.
