Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Co0.95Fe0.05-ZIF/CC/GCE shows high enzyme-free glucose sensing sensitivity and low micromolar detection limit compared with the pristine Co0.95Fe0.05-ZIF control.
Caveat: Application metric is electrochemical sensing, not direct electrical conductivity.
1,6 · Abstract; 3.2 Glucose-Sensing Performance · Fig. 5; Table 1 · Linked to 5 structured results
The Co0.95Fe0.05-ZIF/CC saliva sensor tracks the same before/after meal trend as a commercial blood glucose meter without sample pre-treatment.
Caveat: The paper reports trend agreement rather than calibration statistics against blood glucose.
8,10 · 3.5 Real sample detection; Novelty statement · Fig. 7 · Linked to 2 structured results
The PET saliva sensor performs worse than the GCE electrode, attributed to internal resistance of the three-electrode system and resistance between Co0.95Fe0.05-ZIF/CC and the working region.
Caveat: No direct impedance values for the PET device are reported.
8 · 3.4 Glucose-sensing performance · Fig. 6 · Linked to 2 structured results
Carbon cloth reduces Co0.95Fe0.05-ZIF nanosheet agglomeration, improves catalyst distribution, increases surface area and improves ion movement channels.
Caveat: Surface area comparison is text-reported; SI pore-distribution plots were not available as images.
5-6 · 3.2 Glucose-Sensing Performance · Fig. 4; Fig. S3 · Linked to 5 structured results
Introducing Fe3+ promotes reconstruction of the Co active centre, changing Co-ZIF from rhombohedral dodecahedron morphology to a 3D flower/nanosheet structure.
Caveat: Mechanistic wording is authors' interpretation from morphology, XRD/FTIR and spectroscopy; no direct in situ evidence reported.
3 · 3.1 Characterization · Fig. 2; Fig. 3 · Linked to 5 structured results
CV peak current linearity against square root of scan rate indicates a surface-diffusion-controlled redox process for Co0.95Fe0.05-ZIF/CC.
Caveat: No fitted slopes or correlation coefficients reported in text.
