“…Gr exhibits very large 2‐D electrical conductivity, large‐specific surface area, remarkable mechanical stiffness, and good biocompatibility; hence, it is considered as an ideal material for electrochemical application. Sun et al used Gr‐MnO 2 nanocomposite modified carbon ionic liquid electrode (CILE) to analyze rutin in the commercial drug samples and found that the modification greatly enhanced electrochemical performances of the electrode …”

Excess amount of analgesic and anti‐inflammatory drug, such as indomethacin, often leads to serious gastrointestinal complications; therefore, amount of such active compound should be regulated in commercial drugs. This study proposes an efficient analytical technique to detect indomethacin selectively. We prepared and investigated electrochemical properties of a manganese dioxide‐graphene nanocomposite film modified glassy carbon electrode (MnO2‐Gr/GCE). The behavior of the modified electrode as electrocatalyst towards indomethacin oxidation was also examined. The cyclic voltammetric results reveal that the electrocatalytic activity for the oxidation of indomethacin can significantly be enhanced on the MnO2‐Gr/GCE. Indomethacin exhibited a sensitive anodic peak at about 0.90 V at MnO2‐Gr/GCE. The data obtained from differential pulse voltammetry showed that the anodic peak currents were linearly dependent on the indomethacin concentrations in the range of 1.0 × 10−7 to 2.5 × 10−5 mol/L with a detection limit of 3.2 × 10−8 mol/L (S/N = 3). Most importantly, the proposed method shows efficient and selective sensing of indomethacin in commercial pharmaceutical formulations. This is the first report of a voltammetric sensor for indomethacin using MnO2‐Gr/GCE. We believe that this new method can be commercialized for routine applications in laboratories.

“…Rutin, also known as vitamin P, exists in many plants and multivitamin preparations. [1][2][3][4] As a avonoid compound, rutin exhibits a broad range of physiological activities, such as antibacterial, anti-aging, antioxidant, and anti-inammatory, and has been widely used for the treatment of hypertension and vascular fragility. 5,6 To date, different methods have been developed for rutin detection, such as capillary electrophoresis, 7 performance liquid chromatography (HPLC), 8 spectrophotometry, 9 and chemiluminescene.…”

“…The detection of RT using CS in electrode modification has been reported with multiwalled carbon nanotubes [ 42 , 43 ], graphene [ 44 ] and graphene with poly (amido amine) [ 45 ]. Moreover, the use of ionic liquids to detect rutin has also been reported using pyridinium and imidazolium ionic liquid on a modified carbon paste and glassy carbon electrodes with detection limits between 0.6 nmol L −1 and 0.09 μmol L −1 [ 33 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 ]. On the other hand, CS and IL composites with rutin have been recently reported to act as an immunosensor with multiwalled carbon nanotubes and [BMIM]BF 4 [ 54 ].…”

This work reports the development of a composite of the ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM]BP4) and chitosan (CS) described in previous reports through a new method using cyclic voltammetry with 10 cycles at a scan rate of 50.0 mV s−1. This method is different from usual methods such as casting, deposition, and constant potential, and it allows the development of an electroactive surface toward the oxidation of rutin by stripping voltammetry applied to the detection in tropical fruits such as orange, lemon, and agraz (Vaccinium meridionale Swartz), with results similar to those reported in previous studies. In addition, the surface was characterized by electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM), and Raman spectroscopy. The limit of detection was 0.07 µmol L−1 and the relative standard deviation (RSD) of 10 measurements using the same modified electrode was 0.86%. Moreover, the stability of the sensor was studied for six days using the same modified electrode, where the variation of the signal using a known concentration of rutin (RT) was found to be less than 5.0%. The method was validated using a urine chemistry control spiked with known amounts of RT and possible interference was studied using ten substances including organic and biological compounds, metal ions, and dyes. The results obtained in this study demonstrated that this electrodeveloped composite was sensitive, selective, and stable.
