a The CL intensity as analyte concentration varied. Linear correlation between CL intensity and b the concentration or c the logarithmic concentration of three analytes. d Simulation of H₂O₂ diffusion in three rectangular channels. Dr. Siwei Bai from the Department of Electrical and Computer Engineering, Technical University of Munich, provided assistance with the numerical simulations. e Concentration distribution of H₂O₂ in a rectangular channel at different times. f CL response for different analytes using the related reagents for glucose, lactate, and pyruvate to demonstrate the detection specificity. g Chemiluminescence intensities of glucose (i), lactate (ii), and pyruvate (iii) were measured on chips stored at 4 °C for varying durations. Data were mean ± SD and representative of at three independent experiments.
