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

Ni/Mn-MOF/GCE provides amperometric OSIM sensing with two wide linear ranges, 0.16 uM LOD, selectivity against tested interferents, reproducibility, repeatability and stability.

Caveat: Performance is application-specific for OSIM in alkaline electrolyte; no independent validation dataset is provided.

Application RelevanceSupport assessment: High

The Ni/Mn-MOF/GCE sensor was applied to OSIM detection in serum samples with recoveries of 98 to 101.71% and RSD below or equal to 1.31%.

Caveat: The table's found concentrations exceed added spike values for several rows, so raw table values should be interpreted as reported total found concentration/standard-addition output.

Phase AssignmentSupport assessment: Medium

FESEM, EDS/EDX and XRD support successful synthesis of crystalline Ni/Mn-MOF with C, O, Mn and Ni present and no metal oxide/hydroxide impurity peaks detected by XRD.

Caveat: No empirical formula, elemental percentages, BET porosity, CIF or full structure refinement are reported.

Structure Property LinkSupport assessment: Medium

The porous spherical Ni/Mn-MOF morphology is proposed to increase surface area and facilitate fast electrolyte-ion transfer to the electrode surface.

Caveat: Surface area and ion-diffusion coefficients were not measured directly.

Transport MechanismSupport assessment: High

OSIM oxidation on Ni/Mn-MOF/GCE is described as diffusion-controlled because oxidation peak current varies linearly with the square root of scan rate.

Caveat: The reported regression is for peak current versus square-root scan rate; raw data are graphical.

p006 · Cyclic Voltammetric Responses of OSIM · Fig. 5E · Linked to 1 structured result

Transport MechanismSupport assessment: Medium

Ni/Mn-MOF/GCE shows higher electrocatalytic response than bare GCE for OSIM oxidation, attributed to Ni/Mn redox reactions, enlarged surface area and good conductivity.

Caveat: No four-probe or direct electronic conductivity measurement is reported; conductivity is inferred from electrochemical response.
