Electrochemical Determination of Uric Acid Using a Nanocomposite Electrode with Molybdenum Disulfide/Multiwalled Carbon Nanotubes (MoS@MWCNT).

This paper presents an application for a molybdenum disulfide nanomaterial with multiwalled carbon nanotubes (MoS@MWCNT/E) in a modified electrode substrate for the detection of uric acid (UA). The modified electrode generates a substantial three-fold increase in the anodic peak current for UA compared to the unmodified MWCNT electrode (MWCNT/E). The MoS@MWCNT/E surface was characterized by cyclic voltammetry (CV), scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS) and electrochemical impedance spectroscopy (EIS).

Development of a microcomposite with single-walled carbon nanotubes and NdO for determination of paracetamol in pharmaceutical dosage by adsorptive voltammetry.

This study presents for the first time a new composite of carbon paste (CP), single-walled carbon nanotubes (SWCNTs) and NdO (Nd). This versatile composite (Nd-SWCNT/CPE) was applied to the oxidation of paracetamol (PCM). The newly formed surface was characterized by scanning electron microscopy (SEM), electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV).
