Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The AP1/N-Cu-MOF/GCE aptasensor selectively detects DON with negligible response to several co-occurring mycotoxins.
Caveat: Selectivity bar heights are figure-read estimates except for the common 2 ng mL-1 concentration.

The aptasensor was not suitable for recycling.
Caveat: No recycling data are shown in the supplied figures.
p006 · 2.5 Selectivity and Reproducibility
N-Cu-MOF functions both as an aptamer support with large surface area and as an electrochemical signal probe for DON sensing.
Caveat: No standalone numeric electrical conductivity value is reported.
p001 · Abstract · Linked to 4 structured results
The N-Cu-MOF is assigned as a high-crystallinity HKUST-1-type Cu-based MOF whose framework is retained after PVP introduction.
Caveat: Assignment is based on comparison with reported HKUST-1 peaks; no CIF or Rietveld refinement is provided.
p003 · 2.1 Characterization · Figure 2D · Linked to 4 structured results
AP1 binds N-Cu-MOF through amino group-copper complexation, suppressing the N-Cu-MOF signal until DON binding removes aptamer from the MOF surface.
Caveat: Mechanistic interpretation is inferred from spectral shifts and DPV response rather than direct binding thermodynamics.
