As glucose can be oxidized by GOD

Fig. 14. The linear relationship between the fluorescent intensity ratio I0/I and the concentration of glucose. I0 and I are the fluorescence intensity of IL/copper–CdSe QDs system in the absence and presence of the glucose, respectively. Conditions: different concentrations of Dorsomorphin and 6 U mL−1 GOD incubated in phosphate buffer (0.1 M, pH 7.5) at 25 °C for 5 min. 50 μL of this solution (mixture of glucose and glucose oxidase) was added into the solution of CdSe QDs, 1 mg mL−1; [(1,3-Pr2im)Br], 2 M; Cu2+, 0.002 M in phosphate buffer (0.1 M, pH 7.5) and incubation for 5 min and the PL spectrum was recorded.Figure optionsDownload full-size imageDownload as PowerPoint slide
