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.
GOD-GA-Ni/Cu-MOFs (7:1)-FET gives wide-range glucose detection, high low-range sensitivity, low LOD, specificity and reproducibility.
Caveat: Long-term stability is limited; most performance values are reported in text/table with SI plots as supporting evidence.
7 · Conclusion · Linked to 5 structured results
The enzyme sensor does not have good long-term stability and is positioned as a disposable real-time glucose sensor.
Caveat: Detailed current values in Fig. S17 were not digitised; the main text and rendered SI support the qualitative storage trend.
7 · Conclusion · Fig. S17 · Linked to 4 structured results
Ni/Cu-MOFs (7:1), Ni-MOFs and Cu-MOFs have similar crystal structures based on consistent PXRD peak positions.
Caveat: No CIF is available locally; assignment relies on PXRD comparison in the article and SI.
3 · 3.1 · Fig. 2a · Linked to 2 structured results
XPS shifts are interpreted as local electron transfer between Ni and Cu through the aromatic ligand, producing a Ni-Cu coupling effect.
Caveat: Mechanistic interpretation is inferred from binding-energy shifts rather than directly measured carrier pathways.
4 · 3.1 · Fig. 2d · Linked to 5 structured results
The synergistic effect of Ni and Cu in Ni/Cu-MOFs improves carrier transfer, active metal sites and FET current compared with monometallic controls.
Caveat: Main text reports relative current improvement but does not provide an absolute conductivity value.
5 · 3.2 · Fig. S9 · Linked to 2 structured results
Glucose oxidase converts glucose to gluconolactone and hydrogen peroxide; generated H+ decreases conductance of p-type Ni/Cu-MOF channel layers under negative gate voltage.
Caveat: Mechanism is consistent with controls but proton accumulation is not directly quantified.
