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

Co CPSs/MPC-2 is the best-performing composite for glucose oxidation and sensing among the tested MPC loading series.

Caveat: Application performance is from alkaline electrochemical testing on drop-cast GCEs; no direct bulk transport measurement is reported.

Application RelevanceSupport assessment: High

Co CPSs/MPC-2-GCE shows high selectivity against tested interferents and acceptable recovery in human serum samples.

Caveat: Serum table provides recovery/RSD but not full matrix handling details.

141-144 · 3.2 · Fig. 10; Table 2 · Linked to 7 structured results

Composite RoleSupport assessment: High

MPC provides excellent conductivity and lowers the charge-transfer resistance of Co CPSs/MPC relative to pristine Co CPSs-GCE.

Caveat: Evidence is electrochemical impedance in redox electrolyte rather than direct four-probe conductivity.

Phase AssignmentSupport assessment: High

FT-IR shift of the C=O stretching band indicates coordination of isophthalate carboxylate groups to Co2+ in Co CPSs.

Caveat: No crystal structure or formula is reported; the material is described as amorphous.

Structure Property LinkSupport assessment: Medium

The high Cdl and ECSA of Co CPSs/MPC-GCE indicate more effective active sites, supporting enhanced glucose oxidation.

Caveat: Cdl/ECSA values are electrochemical estimates, not direct surface-area measurements.

Transport MechanismSupport assessment: Medium

Glucose oxidation on MPC-GCE, Co CPSs-GCE and Co CPSs/MPC-2-GCE is assigned as diffusion-controlled based on current increasing with square root of scan rate.

Caveat: The fitted slopes/R values are shown in figures but not tabulated in text.
