Amperometric determination of bisphenol A in milk using PAMAM–Fe3O4 modified glassy carbon electrode

Electrochemically reduced graphene oxide modified acetylene black paste electrode for the sensitive determination of bisphenol A

“…In addition, for further demonstrating the advantages of the fabricated sensor in this work, the determination results obtained by this method were also compared with other electrochemical methods and listed in Table 2. As shown in Table 2, the linear ranges and detection limits shown in this work were superior to the results reported previously [19][20][21][22][23][24][25][26][27][28]. The enhanced performance of GR/ABPE can be attributed to the combination of the excellent properties of GR and AB described above.…”

“…An effective way to overcome these barriers is electrode modification. Some chemically modified electrodes have been reported [19][20][21][22][23][24][25][26][27][28], and comparative analytical figures of merit for different electrodes for the determination of BPA are summarized in Table 2. Each approach has its particular sensitivity and is subject to various limitations.…”

Design of ultrasensitive bisphenol A–aptamer based on platinum nanoparticles loading to polyethyleneimine-functionalized carbon nanotubes

“…These instrument-based techniques offer high sensitivity and accuracy and low detection limit but they are expensive and require time-consuming sample pre-treatment steps and trained operators, which limit their wide applications. Moreover, direct electrochemical methods have been employed for determination of BPA due to their specific properties such as simplicity, fast response, high dynamic range, high sensitivity, excellent selectivity, and low [20,21]. But, they are suffering from fouling of electrode surface by BPA oxidation product which leads to the limitation for applicability of this technique.…”

A label-free photoelectrochemical aptasensor for bisphenol A based on surface plasmon resonance of gold nanoparticle-sensitized ZnO nanopencils

“…It exhibited that binding energy of Au 4f 7/2 showed a negative shift of 0.6 eV in comparison to 84.0 eV of bulk Au (Li et al 2014b;Ranasingha et al 2015). It was commonly believed that this slight shift was caused by electron transfer from Au to ZnO due to the strong electronic interaction between Au nanoparticles and ZnO Yin et al 2011). Furthermore, the other peaks centered at 88. respectively.…”

“…The liquid milk samples were pretreated according to the references (Yin et al 2011) with the same modification. Briefly, 20 mL milk was mixed with 40 mL anhydrous alcohol.…”
