MoS2 microflowers based electrochemical sensing platform for non-enzymatic glucose detection

The detection of glucose plays a critical role in the areas of clinical diagnosis, food analysis, and biotechnology. Here, a MoS2 mircoflower based non-enzymatic glucose sensing strategy was suggested. The MoS2 microflowers were synthesized by hydrothermal method using cetyltrimethylammonium bromide (CTAB) as surfactant and fabricated a non-enzymatic glucose biosensor. The experimental results showed that the prepared MoS2 were flower-like microstructures. Moreover, when pH = 8, concentration of CTAB is 16 mM, and annealing temperature is 500 degrees C, the MoS2 microflowers is more suitable to fabricate electrode. Electrochemical tests showed that the electrode exhibited synergistic electrocatalytic activity with a high sensitivity of 570.71 mA mM (1). A good linear relationship between the anodic peak current and glucose concentration was obtained in the range from 0 to 30 mM. This work puts the flower-like MoS2 materials into application as the electrochemical sensing platform for non-enzymatic glucose detection. (C) 2016 Elsevier B.V. All rights reserved.
