Porphyrin functionalized porous carbon derived from metal–organic framework as a biomimetic catalyst for electrochemical biosensing

consumption. The biomimetic sensor enables a reliable and sensitive determination of glucose with a linear range of 0.5 to 18 mM and a detection limit of 0.08 mM at a signal-to-noise ratio of 3. Moreover, the biosensor exhibits the analytical reproducibility and stability with a lower relative standard deviation of 4.2%. In an application to detect glucose in human serum samples, this glucose biosensor had good detection accuracy with analytical recoveries from 97.3% to 107.7%. Therefore, the porphyrin functionalized PC provides a promising biomimetic platform for constructing the biosensors, and has potential application in bioanalysis and clinical diagnosis.
