Facile Synthesis Of Fes Nanosheets As Peroxidase Mimic For Sensitive Colorimetric Detection Of Blood Glucose

Nanozymes have attracted much attention in biomedical applications. FeS nanosheets with excellent peroxidase-like activity were produced by a solvothermal methodology, which could be used as nanozymes. To test peroxidase-like activity, a glucose colorimetric biosensor was successfully constructed based on FeS nanosheets. Remarkably, the constructed sensor afforded good enough performance for detectiong of glucose in a linear range of 1-150 mu M with a low detection limit is to be 0.3 mu M. Importantly, blood glucose in human serum samples could be detected successfully by this technique, which is promising for clinical-application.
