A facile synthesis of nanostructured CoFe₂O₄ for the electrochemical sensing of bisphenol A

Abstract

A new electrochemical sensor for bisphenol A is reported. CoFe2O4 nanoparticles were synthesized by a sol–gel combustion method. A nanoparticle-modified glassy carbon electrode exhibited outstanding electrochemical performance for the detection of bisphenol A.

Graphitic Carbon-Coated PtCoNi Alloys Supported on N-Doped Porous Carbon Nanoflakes for Sensitive Detection of Bisphenol A

“…The slope value of 63 mV/pH is approximately close to the theoretical value of 57.6 mV/pH (291.15 K) . These results prove that the transferred electrons and protons are numerically equal during the oxidation process of BPA Figure C presents the oxidation process.…”

Core‐shell Hierarchical Enzymatic Biosensor Based on Hyaluronic Acid Capped Copper Ferrite Nanoparticles for Determination of Endocrine‐disrupting Bisphenol A

“…Although ferrite structures have been used as one of the components of various composite systems for the detection of analytes such as dopamine [62], pesticides [63], paracetamol [64] in recent years sensor designs containing BPA very few ferrite structures are encountered. As seen in Table 1, these structures generally didn't contain any modification process on their surfaces and they were not enzymatic systems [11,31b, 57]. BPA sensors containing enzymes, biopolymers and structures such as carbon black [15] or MWCNT [28] having toxic properties have been used.…”

Cobalt-nickel phosphide supported on reduced graphene oxide for sensitive electrochemical detection of bisphenol A

“…Electrochemical sensing emerges as a cost-effective, highly selective, easily operable, and efficient solution, offering swift response times for target analyte detection. Various electrode materials have been explored for BPA detection, including transition metal oxides [ [6] , [7] , [8] ], sulfides [ 9 , 10 ] selenides [ 11 , 12 ], carbon materials [ [13] , [14] , [15] ], and noble metals [ [16] , [17] , [18] ], aiming to enhance the performance of electrocatalytic and analytical sensors. However, the existing sensors fall short of meeting the mandated parametric value.…”
