Figure 3. (A) UV-Vis spectra of CLCN-IPN films immobilized with varying concentrations of C_Gox, tested using 2 mM glucose aqueous solution for 2 h. The insets show corresponding photographs of the biosensor films; (B) The λ_PBG values exhibit an increase with rising C_Gox concentration; (C) A linear increase in λ_PBG is observed in CLCN-IPN films treated with different concentrations of C_Glucose. Insets display photographs taken 2 h after the addition of C_Glucose aqueous solutions; (D) Bar graph illustrating the Δλ_PBG values as a function of C_Glucose concentration in aqueous solutions. Error bars in (B-D) represent the standard deviation from triplicate experimental results. UV-Vis: UV-Visible; CLCN: cholesteric liquid crystal network; IPN: interpenetrating polymer network.
