Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Cu-HHTT/CF functions as a bifunctional non-enzymatic sensor for glucose and H2O2 with low detection limits and high reported sensitivities.
Caveat: Reported sensitivity units appear unusually large relative to the calibration slopes; values were preserved as printed.
10 · Conclusions · Linked to 4 structured results
The Cu-HHTT/CF sensor was applied to serum, orange juice and milk samples with reported recoveries/RSDs supporting practical sample detection.
Caveat: Associated amperometric traces for H2O2 milk samples are in missing Fig. S9.

Cu-HHTT cube-shaped MOF material was successfully synthesised on copper foam.
Caveat: Full crystallographic detail and SI figures/tables were not available locally.
3 · Material characterization · Fig. 2 · Linked to 5 structured results
Glucose oxidation on Cu-HHTT/CF is diffusion-controlled.
Caveat: Some supporting Epa/Epc analysis is in missing Fig. S3.

H2O2 electroreduction on Cu-HHTT/CF is diffusion-controlled.
8 · Electrochemical determination of H2O2 · Fig. 6c · Linked to 2 structured results
The Cu-HHTT/CF electrode has lower charge-transfer resistance than the ligand-control electrode, attributed to an electronic channel that improves electron transfer.
Caveat: The main text contains Cu-HHTP/CP and HHTP/CP variants and the supporting EIS figure is missing.
