Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
GOx@Zn-HHTP maintains ECL response under harsh treatments and reusable cycling, supporting sensor stability.
Caveat: Individual bar values from Fig. 5A are not all reported exactly in text.

Operating the GOx@Zn-HHTP ECL glucose sensor at pH 10.0 increases sensitivity 8.5-fold and lowers the detection limit to 0.002 uM relative to pH 7.0.
Caveat: Sensitivity comparison is based on slopes of logarithmic calibration equations.
p006 · 3.5 Performance of the proposed ECL sensor · Fig. 4D · Linked to 6 structured results
The GOx@Zn-HHTP ECL sensor quantified glucose in human sweat samples at 0.058-0.094 mM detected glucose, with 91.70-100.56% spike recovery.
Caveat: Three volunteer samples; Table S1 gives n = 3 recovery values but not participant metadata.

The application paper does not report a separately synthesised pristine Zn-HHTP control sample or first-hand conductivity measurement.
Caveat: Based on inspection of the supplied main text and SI text; prior work is cited for conductive MOF nanocapsules.
p002 · Introduction · Linked to 1 structured result
The Zn-HHTP nanocapsule improves GOx alkaline stability, retaining about 80% activity at pH 10.0 while free GOx retains about 30%.
Caveat: Values are approximate text-reported percentages from Fig. 2B.
p003 · 3.2 Alkaline stability · Fig. 2B · Linked to 2 structured results
FTIR amide I and amide II bands support the presence of GOx in the Zn-HHTP composite.
Caveat: No quantitative enzyme loading is reported.
p003 · 3.1 Characterizations of prepared materials · Figure S2 · Linked to 2 structured results
GOx@ZIF-8 transforms into hollow GOx@Zn-HHTP nanocapsules with XRD peaks consistent with Zn-HHTP.
Caveat: No raw diffraction data or CIF is supplied.
p003 · 3.1 Characterizations of prepared materials · Fig. 1 · Linked to 3 structured results
GOx@Zn-HHTP nanocapsules are porous, with 475.728 m2 g-1 BET area and mainly 1.2 nm micropores.
Caveat: Main text reports the numeric porosity values; rendered SI Figure S3 provides supporting plot context.
