Sensitive determination of bisphenol A base on arginine functionalized nanocomposite graphene film

Electrochemical determination of bisphenol A with a glassy carbon electrode modified with gold nanodendrites

“…As shown in Table 1, the peak currents of the as-developed method are comparable with those from other electrochemical methods in the literature [4,[34][35][36][37][38]. It might be attributed to the unique structures of gold nanodendrites [39] and subsequent self-assembly of 4-MBA.…”

“…It demonstrates that 4-MBA/gold nanodendrites/GCE has the enhanced anti-interference ability and improved selectivity. Compared with the other electrochemical sensors [4,[34][35][36][37][38], the as-developed method has good selectivity for detection of BPA, which can be applied for potential detection of BPA in real samples.…”

Aptamer-functionalized nanoporous gold film for high-performance direct electrochemical detection of bisphenol A in human serum

“…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.…”

Synergistic Effect of Lithium Perchlorate and Sodium Hydroxide in the Preparation of Electrochemically Treated Pencil Graphite Electrodes for Selective and Sensitive Bisphenol A Detection in Water Samples

“…To overcome these limitations, modification of electrode surfaces using different approaches has been performed lately. In this context, Mg-Al-CO 3 layered double hydroxide [14], the imprinted sol-gel [15], MWCNT-melamine complex [16], fullerene-C 60 [1], Ndoped graphene sheets [17], SWCNT-cyclodextrin [18] and arginine functionalized nanocomposite graphene [19] have been employed in the modification of glassy carbon electrodes. Moreover, boron doped diamond electrode [20], mesoporous silica modified carbon paste electrodes [21] and polyaniline nanorods-multiwalled carbon nanotube modified basal plane pencil graphite [22] were also employed in the determination of BPA.…”
