ZrO 2 decorated nanocrystalline ZSM-5 nanocomposites with different weight ratios were prepared by the calcination of physical mixture of nanocrystalline ZrO 2 and Nano-ZSM-5.Material was characterized by the complementary combination of X-ray diffraction, N 2adsorption, and transmission/scanning electron microscopic techniques. An electrochemical sensor based on ZrO 2 supported nanocrystalline zeolite was developed for the nanomolar detection of organic water pollutants metol and bisphenol A with high electrocatalytic activity, stability, sensitivity, and selectivity. Under the optimum condition, a wide linear range was obtained from 4 nM-800 µM and 6 nM-600 µM with a limit of detection of 1 nM and 3 nM for metol and bisphenol A, respectively. The analytical performance of the developed sensor was demonstrated for the determination of metol and bisphenol A in different real samples such as river water, metol in photographic solution, and bisphenol A in baby bottle with satisfactory results.

Azo dye functionalized graphene nanoplatelets for selective detection of bisphenol A and hydrogen peroxide

Graphene nanoplatelets (GNP) have emerged as a promising electrode material for electrochemical sensing applications because of their high conductivity, large surface-to-volume ratio, biocompatibility, and low cost. However, GNP are not soluble in water. We dispersed GNP in water with the assistance of a tri-azo dye, Direct blue 71 (DB). Thin films prepared with GNP/DB dispersion were characterized by scanning electron microscopy (SEM), Raman spectroscopy, and UV-vis spectroscopy, which indicated the binding of DB with GNP films. The GNP/DB film coated glassy carbon electrode (GCE) exhibited high electrocatalytic activity to oxidation of bisphenol A (BPA) and reduction of hydrogen peroxide (H 2 O 2 ). The GNP/DB film greatly enhanced the BPA oxidation peak current at +524 mV, and the H 2 O 2 reduction peak current at -400 mV vs. Ag/AgCl in pH 7.0 phosphate-buffered saline (PBS) solution. The oxidation peak current was proportional to BPA concentration from 10 nM to 100 nM and 100 nM to 25 µM, with a limit of detection of 1.23 nM. The GNP/DB-modified GCE also showed remarkable decrease of over-potential for the reduction of H 2 O 2 with a fast amperometric response of less than 2 s, good linear range of 10 µM to 1.9 mM, and high sensitivity of 57.6 µA/mM. The fabricated sensor shows good reproducibility and stability with limited interference. Furthermore, the sensor was successfully applied to determine BPA in spiked commercial milk and juice samples.A new electrochemical sensor is developed based on graphene nanoplatelets functionalized with tri-azo dye (Direct blue 71) for selective and highly sensitive detection of bisphenol A and hydrogen peroxide in pH 7 phosphate buffered saline solution.

“…These chromatography and mass spectrometry-based techniques can analyze BPA with high sensitivity, however, large capital investment, skilled operators, and cumbersome sample preparation and pretreatment are required, reducing their applicability of on-site and rapid detection of BPA in various samples and matrices [9,11]. The other recently developed methods for BPA detection include enzyme-linked immunosorbent assay (ELISA) [12], fluorescent method [13], surface-enhanced Raman scattering [14,15], colorimetric methods [16], and electrochemical sensors [17][18][19][20][21][22][23][24][25][26][27][28][29]. Among those methods, electrochemical sensors are the widely accepted and employed group due to their simple operation, rapid response time, low cost, high sensitivity, potential for miniaturization, and capability of real sample analysis [9], thereby having promising potential for BPA analysis in human internal fluids.…”

“…To enhance the detectable signals, nanomaterials that possess large specific surface area and electrocatalytic property are usually utilized to catalyze the redox reaction of BPA. Electrochemical sensors that were developed with metal nanoparticles [18], quantum dots [19], carbon nanotubes [20,21], graphene [17,[22][23][24], and the composite of nanomaterials [25][26][27] have been reported for the detection of BPA. Besides BPA, however, there are many other phenolic compounds that also can be electrocatalyzed by the nanomaterials mentioned above, which may interfere the detection of BPA.…”
