“…In addition to GNP noble metal, Pt nanoparticles (PtNPs) could also be applied to construct the immunosensor. Recently, a novel human chorionic gonadotropin (hCG) immunosensor was fabrication based on PtNPs and the GN/IL/chitosan nanocomposite [105]. Besides, rutin was used for the first time as the redox probe in the electrochemical immunosensor.…”

“…Among the several magnetic materials reported in the literature for analytical detection [20][21][22][23][24][25][26][27][28][29][30], iron oxides (mainly Fe 3 O 4 ) nanoparticles are the most used due to its simple preparation and superparamagnetic properties [31][32][33][34][35][36]. Iron oxide nanoparticles can be applied for simple adsorption of biomolecules [37], functionalized and/or encapsulated with polymers or silica materials for making hybrid composites, providing increased functionality [38]and biocompatibility [39].…”

A novel platform for carbamate-based pesticide quantification using a chitosan/magnetic iron oxide (Chit-FeO) nanocomposite as a glassy carbon electrode (GCE) modifier is shown for an analytical methodology for determination of bendiocarb (BND). The BND oxidation signal using GCE/Chit-FeO compared with bare GCE was catalyzed, showing a 37.5% of current increase with the peak potential towards less positive values, showing method's increased sensitivity and selectivity. Using square-wave voltammetry (SWV), calibration curves for BND determination were obtained (n = 3), and calculated detection and quantification limits values were 2.09 × 10 mol L (466.99 ppb) and 6.97 × 10 mol L (1555.91 ppb), respectively. The proposed electroanalytical methodology was successfully applied for BND quantification in natural raw waters without any sample pretreatment, proving that the GCE/Chit-FeO modified electrode showed great potential for BND determination in complex samples. ᅟ Graphical abstract.

“…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 ]. Most of these reports use other substances such as graphene, carbon nanotubes, nanoparticles, and conductive polymers.…”

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.
