High-performance carbon black/molybdenum disulfide nanohybrid sensor for cocoa catechins determination using an extraction-free approach

Class-selective voltammetric determination of hydroxycinnamic acids structural analogs using a WS2/catechin-capped AuNPs/carbon black–based nanocomposite sensor

“…After the boost of graphene in the analytical and materials sciences, more recently other two-dimensional graphene-like NMs started to be studied. In particular, transitions metal dichalcogenides (TMDs) have received great attention because of their chemistry, physical properties, and versatility [6][7][8][9][10]. However, their employment in the development of sensors for the analysis of real matrices needs to be further explored [7,11].…”

“…However, their employment in the development of sensors for the analysis of real matrices needs to be further explored [7,11]. The main limitation of TMDs [9] is linked both to the intrinsic low conductivity and massive tendency to the "restacking" phenomenon, regardless of the type of synthesis/exfoliation and the resulting conformation of the sheets [13]. Nevertheless, TMDs have demonstrated to be elective building blocks for the development of hybrids nanomaterials, giving rise to improved and sometimes unexpected properties [8][9][10][11].…”

Fast, Simple and Sensitive Determination of Coumaric Acid in Fruit Juice Samples by Magnetite Nanoparticles‐zeolitic Imidazolate Framework Material

“…Among them, voltammetric determination of polyphenols including CA has gained the most attention due to its stability, fast response and sensitivity. Recent accelerated studies have been conducted to determine antioxidants in real samples using electrochemical methods [17][18][19][20]. Thus, numerous inor-ganic and organic modified nanomaterials such as carbon nanotubes, graphene or metal oxide nanoparticles have been applied for electrochemical sensor for antioxidant [3,[21][22][23].…”

Electrochemical determination of tetrabromobisphenol A in water samples based on a carbon nanotubes@zeolitic imidazole framework-67 modified electrode

“…What is more, the prepared composite was used in the determination of phenol like analytes. [27][28][29][30][31][32] In the eld of electrochemical, MOF-based electrodes were usually modied with conductive materials, such as Au nanoparticles 33 and Naon® ion exchangers. 34 Though the performance of carbon materials in improving the electrode conductivity is preferable, the application of carbon materials to the preparation of MOF-based sensors is still limited.…”
