Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The Cu3(HHTP)2/DNA hydrogel POCT method provides dual colourimetric and temperature detection of T-2 toxin over 5-200 ng/mL with a 1.67 ng/mL LOD.
Caveat: Application performance is for the full hydrogel reaction system, not pristine Cu3(HHTP)2 alone. SI Table S2 separately reports a 12.83 ng/mL colourimetric LOD, while the main text reports a 1.67 ng/mL overall method LOD.
8 · 4. Conclusion · Linked to 5 structured results
Although the material is described as a conductive MOF, this paper does not report direct electrical conductivity, thermoelectric, porosity or electrochemical measurements for Cu3(HHTP)2.
Caveat: The assigned article reports structure, optical/photothermal, peroxidase-like catalytic and sensing data only.
2 · Introduction
The DNA hydrogel acts as a target-responsive carrier that hides and then releases Cu3(HHTP)2 active sites in the presence of T-2 toxin.
Caveat: The mechanism is supported by gel electrophoresis and response tests, but the hydrogel structure is not deeply structurally characterised.
5 · 3.3. Principle for T-2 toxin · Scheme 1; Fig. 3 · Linked to 3 structured results
The reported XRD peaks and TEM morphology support successful synthesis of Cu3(HHTP)2.
Caveat: No CIF or Rietveld refinement is supplied in the assigned files.
3 · 3.1. Materials characterization · Fig. 1 · Linked to 4 structured results
Cu3(HHTP)2 exhibits peroxidase-like catalytic activity for TMB/H2O2 oxidation.
Caveat: Main text and SI Table S1 report inconsistent Km/Vm values for Cu3(HHTP)2; both source-specific sets are retained and labelled by provenance.
3 · 3.2. Peroxidase-like activity · Figure S1; Table S1 · Linked to 8 structured results
Cu3(HHTP)2 shows strong broad optical absorption and efficient photothermal conversion under 808 nm irradiation.
Caveat: Endpoint temperatures from Fig. 2A concentration series are visual estimates, but the conversion efficiency is text/SI-table reported.
