? 2022 The Korean Society of Industrial and Engineering ChemistryHerein, a novel composite material (Magnesium co-doped Tin (IV) oxide; MTO) microcube was synthesized by a simple solution method in basic phase and successfully characterized. It has been used the Fourier Transform Infrared Spectroscopy (FTIR), X-ray Photoelectron Spectroscopy (XPS), X-ray Diffraction (XRD), Field Emission Scanning Electron Microscope (FESEM), and Energy-Dispersive Spectroscopy (EDS) techniques for the characterization of MTO. The MTO microcube was used later to modify gold-coated μ-chips to detect unsafe toxin, bisphenol A (BPA) in aqueous medium. Notable sensing performance was achieved with excellent sensitivity (1.63 μAμM?1cm?2), fast response time (～11 s), wide linear dynamic range (LDR = 0.10 nM – 1.0 mM: R2 = 0.9997), ultra-low detection limit (2.7 ± 0.1 pM at S/N = 3) and excellent reproducibility and repeatability for the MTO/Au/μ-Chip sensor. This MTO fabricated gold-coated μ-chip was further applied with appropriate quantification and determination results in real environmental sample analyses.
