Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The aptasensor was validated in beer matrices, with treated-beer recoveries of 83.6-98.0% and RSDs of 3.35-5.37%.
Caveat: Only main-text recovery/RSD ranges could be extracted because the SI text lists Tables S2-S3 but omits their bodies.

The C-Ni1.5Co1.5(HITP)2/Exo III aptasensor detects T-2 toxin over 5e-7 to 50 ng/mL with LOD 1.67e-7 ng/mL and good calibration linearity.
Caveat: Application metric from sensor assay, not intrinsic conductive-MOF transport.

The authors state that the aptasensor construction process is time-consuming and not conducive to practical applications.
9 · 4. Conclusions
Loading AuNPs and thionine on C-Ni1.5Co1.5(HITP)2 produces a composite probe with stronger current response and lower interfacial charge-transfer resistance than the MOF alone.
Caveat: No numeric Rct values are reported in main text.

The mesoporous C-Ni1.5Co1.5(HITP)2 structure is favourable for thionine loading and charge transfer, supporting signal amplification.
Caveat: Probe-loading quantification is not reported in the main text.

Moderate Co incorporation into Ni3(HITP)2 enhances electrochemical conductivity proxies and thionine signal amplification, with Ni1.5Co1.5(HITP)2 giving the strongest response; excess Co reduces performance by disrupting the structure.
Caveat: The paper does not report direct conductivity in S/cm for the new NixCo3-x(HITP)2 samples; conductivity is inferred from CV/EIS/SWV modified-electrode behaviour.

C-Ni1.5Co1.5(HITP)2 amplifies thionine electrochemical signal through Co(II)/Co(III) and Ni(II)/Ni(III) spontaneous recycling plus accelerated electron transfer from the conjugated framework.
Caveat: Mechanistic assignment is author interpretation supported by XPS valence assignments and electrochemical trends, not direct operando valence tracking.
