Open a family to keep every result attached to its sample, method and conditions.
Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Ag-CoNi-MOF/GCE is reported to have good reproducibility, 20-day stability and anti-interference capability.
Caveat: Interference trace values are approximate visual estimates from the rendered SI; main text gives qualitative selectivity.

Ag-CoNi-MOF/GCE provides sensitive luteolin detection over 0.002-1.0 uM with 0.4 nM LOD and acceptable urine recoveries.
Caveat: Application is electrochemical sensing rather than bulk transport; real-sample testing used spiked diluted urine.

Ag nanoparticle incorporation into CoNi-MOF improves electron transfer/electrical conductivity and reduces EIS impedance.
Caveat: Conductivity is inferred from electrochemical impedance and rate constants rather than a direct solid-state conductivity measurement.
4 · 3.1 · Fig. 3a · Linked to 4 structured results
Ag nanoparticle loading does not cause apparent loss of CoNi-MOF crystallinity or major morphology change.
Caveat: Only powder XRD, SEM/TEM and EDS are reported; no CIF/refinement data were supplied.
4 · 3.1 · Fig. 1; Fig. 2a · Linked to 4 structured results
Ag-CoNi-MOF has slightly higher BET surface area and pore size than CoNi-MOF, supporting improved active-site accessibility.
Caveat: BET increase is small (43.02 to 44.6 m2/g); the paper links this to performance together with Ag conductivity and active sites.
4 · 3.1 · Fig. 2d · Linked to 4 structured results
Luteolin oxidation on Ag-CoNi-MOF/GCE is interpreted as a reversible two-proton/two-electron process and adsorption-controlled.
Caveat: Key supporting plots are in SI figures; rendered SI pages were inspected, while fitted values are reported in the main text.
