Abstract

Abstract: This research, for the first time, demonstrates a direct electrochemical detection of bisphenol A (BPA) using silver oxide (Ag2 O) nanocubes (NCs) modified platinum electrode. The Ag2 O NCs, size ranging from 60 to 100 nm utilized in this research as a smart electro-active sensing platform were pure and synthesized using a cost-effective, affordable, and facile chemical route. The Ag2 O NCs modified electrochemical sensor exhibited a low limit of detection (LOD) as 20 nmol dm −3, high sensitivity as 95 μA (μmol dm −3 ) −1 cm −2, and linear dynamic range (LDR) varies from 80 nmol dm −3 - 4.8 μmol dm −3 . This sensor also showed good selectivity, reproducibility, and reusability for BPA detection. The practical application of developed sensor was also tested using real water samples. The outcomes of this research suggested that Ag2 O NCs based sensor can be useful for effective and efficient electrochemical BPA sensing in both real and lab samples. Graphical abstract: Image 1 Highlights: Detection of BPA emerging essential for health care. Electrochemical techniques seem as potential alternative for BPA detection. Ag2 O nanocubes presented here for label free direct sensing of BPA. Ag2 O BPA sensor is highly sensitive with a very low limit of detection. Herein presented sensor is cost-effective with the potential scalability.
