Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The bimetallic Co/Ni-HITP-GA-GOX-FET outperforms monometallic and water-phase controls, reaching 10 nmol/L to 10 mmol/L detection and 39 uA (mol/L)^-1 mm^-2 sensitivity.
Caveat: Comparison-table values for this-work detection range were verified in the rendered SI; prior-literature rows are treated as contextual rather than first-hand results.
5 · Summary · Fig. 5; Fig. S5; Table S1 · Linked to 8 structured results
The Co/Ni-HITP-GA-GOX-FET is presently mainly considered for one-time detection because response declines after longer storage/washing.
Caveat: The exact Fig. S6 traces could not be re-read from rendered SI images, but the main text reports summary values.
5 · Glucose sensing performance · Fig. S6 · Linked to 4 structured results
GOX modification is required for significant glucose response; pristine Co/Ni-HITP-FET and GA-only controls do not respond significantly.
Caveat: Quantitative control currents are only available from figures; provided text describes the controls qualitatively.
5 · Glucose sensing performance · Fig. 5b-d · Linked to 3 structured results
Opposite Co 2p and Ni 2p binding-energy shifts indicate electron transfer/coupling between Co and Ni through the HITP aromatic ligand.
Caveat: The electron-transfer direction is based on XPS binding-energy shifts and the authors' interpretation.
3 · Results · Fig. 3c-d · Linked to 4 structured results
DMF competes with HITP for metal-ion coordination, slows MOF nucleation, and enables high-crystallinity Co/Ni-HITP film growth on the substrate.
Caveat: Direct mechanistic evidence is inferred from XRD, TGA-MS and morphology comparisons rather than in-situ spectroscopy.
2 · Results · Fig. 1c-e · Linked to 7 structured results
For the p-type Co/Ni-HITP-GA-GOX-FET, enzymatically generated electrons reduce hole-carrier concentration, decrease channel conductivity, and produce a downward drain-current response.
Caveat: Mechanism is consistent with transfer behaviour and sensing response but not independently quantified by carrier-density measurements.
