Author interpretations and caveats

Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.

Application RelevanceSupport assessment: High

The biosensor shows selectivity against tested interferents, 0.93% reproducibility RSD, and low RSD during 20-cycle stability tests.

Caveat: Selectivity bar heights were not digitised; qualitative selectivity is captured in claims rather than numeric results.

Application RelevanceSupport assessment: High

The Ru@Ni3(HITP)2-based ECL biosensor enables ultrasensitive thrombin detection from 1 fM to 1 nM with 0.62 fM LOD.

Caveat: Application result depends on Exo I target-cycling amplification and the full AuNP/aptamer/Fc-S1 electrode architecture.

p005 · 3.5 · Fig. 4 · Linked to 5 structured results

Application RelevanceSupport assessment: High

Human serum spike recoveries near 100% indicate practical applicability for TB detection.

Caveat: Serum assays are spike-recovery tests, not clinical validation across patient samples.

p006 · 3.7 · Table 2 · Linked to 4 structured results

Composite RoleSupport assessment: High

AuNPs provide the effective Au-S anchoring interface for the thiolated thrombin aptamer; pi-pi adsorption of aptamers directly on Ru@Ni3(HITP)2 has negligible influence on detection performance.

Caveat: Evidence is based on ECL quenching/recovery comparison, not direct surface-coverage quantification.

SI text · S-17 · Fig. S12 · Linked to 2 structured results

Phase AssignmentSupport assessment: High

Ru grafting preserves the crystallinity and Ni3(HITP)2 framework structure.

Caveat: Only principal PXRD peak list captured here; full pattern is in Fig. 1A.

p003 · 3.1 · Fig. 1A · Linked to 2 structured results

Phase AssignmentSupport assessment: High

Ru(bpydc) complex was grafted into Ni3(HITP)2 through carboxylate-Ni coordination and electrostatic interaction.

Caveat: Ru(bpydc) location in channels is inferred from combined spectroscopic and charge evidence rather than direct pore imaging.

p004 · 3.1 · Figs. S5-S8 · Linked to 6 structured results

Structure Property LinkSupport assessment: High

Higher M3(HITP)2 carrier conductivity leads to lower Ret and stronger ECL intensity/efficiency for Ru@M3(HITP)2 emitters.

Caveat: Conductivity values are cited from Chen et al. 2020, while EIS/ECL comparisons are first-hand in this paper.

p004 · 3.3 · Fig. 3A-B; Table S2 · Linked to 11 structured results

Transport MechanismSupport assessment: Medium

Hydrophobic porous Ni3(HITP)2 enriches lipophilic TPrA and provides confined conductive channels, improving TPrA oxidation and ECL reaction efficiency.

Caveat: Mechanism is inferred from ECL/CV comparisons; direct TPrA uptake in pores is not separately quantified.
