Figure 5. (A) Δλ_PBG values for the CLCN-IPN_GOx, CLCN-IPN_Lox, and CLCN-IPN_urease sensors tested with artificial sweat Sample 1, containing C_Glucose = 1 mM, C_urea = 20 mM, and C_Lactate = 20 mM. The inset shows a real photograph of the soft wearable array biosensor, where L, U, and G correspond to the lactate, urea, and glucose sensors, respectively; (B) UV-Vis spectra corresponding to the CLCN-IPN films tested with Sample 1; (C) Δλ_PBG values for the CLCN-IPN_GOx, CLCN-IPN_Lox, and CLCN-IPN_urease sensors tested with artificial sweat Sample 2, containing C_Glucose = 1 mM, C_urea = 50 mM, and C_Lactate = 50 mM. The inset shows a real photograph of the soft wearable array biosensor after exposure to Sample 2; (D) UV-Vis spectra corresponding to the CLCN-IPN films tested with Sample 2. CLCN: Cholesteric liquid crystal network; IPN: interpenetrating polymer network; UV-Vis: UV-Visible.
