Figure 3. In situ Entrapment of enzyme under visible light and its application in glucose detection.

(a) Scheme for preparation of enzyme entrapped composite films under visible light. (b) Scheme of the glucose detection reaction catalyzed by GOD and HRP. (c)The absorbance change at 505 nm after immersing LDPE-ENZYME film into glucose solution (C_glucose = 5 mmol/L). The first, second and third data in the figure represents the reuse number of same film. The data labelled UV represents a film with enzymes was entrapped in gel layer under UV irradiation for 3 minutes at intensity of 9000 μW/cm² (λ = 254 nm). (d) Relationship of absorbance with glucose concentration after immersing an LDPE-ENZYME film into glucose solution for 10 minutes. All values were averaged of 3 repeats and error bars correspond to the standard deviation.
