Rapid and accurate detection of changes in glucose (Glu) hydrogen peroxide (H2O2) concentrations is essential for the predictive diagnosis diseases. Electrochemical biosensors exhibiting high sensitivity, reliable selectivity, rapid response provide an advantageous promising solution. A porous two-dimensional conductive metal-organic framework (cMOF), Ni-HHTP (HHTP = 2,3,6,7,10,11-hexahydroxytriphenylene), was prepared by using a one-pot method. Subsequently, it employed to construct enzyme-free paper-based electrochemical sensors applying mass-producing screen-printing inkjet-printing techniques. These effectively determined Glu H2O2 concentrations, achieving low limits 1.30 μM 2.13 μM, sensitivities 5573.21 μA μM-1 cm-2 179.85 cm-2, respectively. More importantly, Ni-HHTP-based showed ability analyze real biological samples successfully distinguishing human serum from artificial sweat samples.
