Facile Facile synthesis of orthorhombic strontium copper oxide microflowers for highly sensitive nonenzymatic detection of glucose in human blood

An efficient cost effective, scalable, template free synthesis of novel strontium copper oxide microflowers via simple co-precipitation fashion. As synthesized SrCuO2 microflowers (SCO MFs) were systematically characterized by X-ray diffraction pattern (XRD), Fourier transformer infrared spectroscopy (FTIR), scanning electron microscope (SEM), energy dispersive spectroscopy (EDS) and elemental mapping. The electrochemical behavior of as fabricated SCO MFs film was characterized by electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CVs). Fabrication of novel SCO MFs films as a proficient non-enzymatic glucose sensor with high sensitivity (2511.27 mu A/mM/cm(2)) over applied potential of +0.45V (vs. Ag/AgCl), fast response (<5s), and broad linear range (0.14-2200 mu M) coupled with lower limit of detection (26 nM). The constructed electrode provides good anti-interference ability with acceptable reproducibility and stability. Moreover, the practical applicability of the architectured sensor was evaluated in human blood samples. (C) 2017 Taiwan Institute of Chemical Engineers. Published by Elsevier B.V. All rights reserved.
