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.
The authors selected 1 mg mL-1 CuTAPc-TFPP-COF dispersion, 100 nM aptamer, 1 h aptamer incubation and pH 7.4 for TC detection after EIS optimisation.
Caveat: Full optimisation curves are shown graphically in Fig. S5; endpoint values are reported in SI text.

The aptasensor is suitable for trace tetracycline determination in river water, milk and pork samples.
Caveat: Based on spiked recovery tests; naturally contaminated samples were not reported.

The CuTAPc-TFPP-COF aptasensor enables ultrasensitive tetracycline detection with an LOD of 59.6 fM over 0.1-100000 pM.
Caveat: Application metric depends on aptamer immobilisation and EIS readout, not on standalone framework conductivity.
PDF p8 · 3.5. Sensitivity · Fig. 5 · Linked to 5 structured results
No direct bulk electrical conductivity, carrier mobility, Hall, Seebeck, or thermoelectric measurement is reported for CuTAPc-TFPP-COF.
Caveat: Search of main and SI text found electrochemical Rct/CV data but no direct transport measurement.

CuTAPc-TFPP-COF is assigned as a novel two-dimensional semiconducting metal covalent organic framework.
Caveat: The paper does not report direct electrical conductivity or band-transport data; semiconducting/conductive character is asserted and supported indirectly by electrochemical activity and conjugated structure.
PDF p1 · Abstract · Linked to 4 structured results
XPS evidence supports successful immobilisation of tetracycline-targeted aptamer strands on CuTAPc-TFPP-COF without destroying the original framework structure.
Caveat: The evidence is spectroscopic; the paper does not quantify aptamer surface coverage directly.
PDF p9 · S3. Electrochemical TC sensing performance · Fig. S3 · Linked to 4 structured results
High surface area, porosity, nanosheet morphology and nitrogen-rich conjugation make CuTAPc-TFPP-COF an effective scaffold for aptamer immobilisation.
Caveat: The contribution of each structural factor is inferred by the authors rather than isolated by controlled experiments.

CuTAPc-TFPP-COF forms from CuTAPc and TFPP through Schiff-base/imine condensation.
Caveat: The final COF synthesis recipe lacks quantities in the supplied main/SI text.
PDF p5 · 3.3. Chemical structure and components · Fig. 2b · Linked to 1 structured result
Tetracycline binding to aptamer-modified CuTAPc-TFPP-COF/GCE increases charge-transfer resistance by hindering electron transfer at the electrode/electrolyte interface.
Caveat: Mechanistic interpretation is based on EIS/CV trends, not direct microscopic observation of TC binding on the electrode.
