Research on Modeling Method of Enzyme Injection Glucose Biosensors

A mechanism model of enzyme injection biosensor was established and the accuracy of the model was verified through experiments in this study. The parameters of the reaction model were determined by fitting the voltage data with model and the voltage data was obtained by detecting 1 and 2 mg mL−1 glucose solution. Accuracy of the model was verified by comparing the fitting curve and the actual curve. The fitting curve was obtained by taking the value of 3 mg mL−1 into the model and the actual data was detected by actual sensors. Experimental results showed that the liquid enzyme Michaelis constant Km was 1.97, the correlation coefficient between mathematical model and the actual sensor working model was 0.998.

This figure illustrates the fitting degree between the actual data and the fitting data. The fitting data was obtained by mathematical model and the actual data was obtained by actual sensor. The superimposed fitting curve and actual curve proved that the mathematical model could well represent the actual voltage variation.Figure optionsDownload as PowerPoint slide
