Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
BSA blocking produced no substantial EIS or current change, so the authors argue this blocking step can be omitted for the ML-Cu2O@Cu-MOF aptasensor.
Caveat: The main text gives qualitative BSA response statements; exact BSA-stage Rct/current values are not stated and Table S2 numeric body is unavailable in the SI text layer.

The ML-Cu2O@Cu-MOF aptasensor achieves low S. aureus LODs of 2 CFU/mL by EIS and 1.6 CFU/mL by DPV over a 10 to 1e8 CFU/mL range.
Caveat: Calibration data points are plotted in Fig. 4 and detailed raw data are not provided in the main text.

Recovery tests in milk, honey, and biscuit indicate practical applicability of the ML-Cu2O@Cu-MOF aptasensor for food-sample analysis.
Caveat: Exact SI recovery rows are available; raw electrochemical traces are not provided.

The mixed-ligand ML-Cu2O@Cu-MOF provides porosity and multiple functional groups that enhance aptamer immobilisation relative to sole-ligand Cu-MOF controls.
Caveat: Table S2 reports electrode-stage Rct values; the paper still does not provide direct bulk MOF conductivity.

Mixed Cu valence states, Cu2O nanocrystals, oxygen vacancies, and crystal defects in ML-Cu2O@Cu-MOF are proposed to improve electrical conductivity and amplify electrochemical response.
Caveat: The paper reports electrochemical interfacial responses, not a direct bulk conductivity value for the MOF powder.
