Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The on-chip micro-biosensor eliminates binder and conductive-carbon additive effects, allowing the sensing performance of the pristine Cu-BHT film surface to be probed.
Caveat: Application claim is specific to the fabricated on-chip architecture in PBS/H2O2 testing.

The main text reports the BS-Cu-BHT amperometric linear range as up to 200 uM, whereas SI Table S1 lists 0.0005-0.4 mM; both values were extracted separately.
Caveat: No raw data were provided to reconcile this discrepancy.

The bottom-side synaptic-like Cu-BHT surface gives higher H2O2 sensing response than the smooth up-side surface.
Caveat: Device comparison is between two orientations of the same pristine film rather than two chemically different frameworks.

ts-Cu defect sites introduced by the synaptic-like bottom-side morphology act as nanozyme-like active sites and are the main factor improving H2O2 sensing.
Caveat: Active-site assignment relies on XPS/Auger deconvolution plus DFT adsorption/reaction modelling; direct operando identification is not reported.
p006 · Results and Discussion · Figure 5 · Linked to 6 structured results
The gas-liquid/aqueous-organic interfacial reaction gives very thin Cu-BHT films that grow oriented from top to bottom along the c-axis, producing a flat up-side surface and a synaptic-like bottom-side surface.
Caveat: The film-growth mechanism is inferred from reaction-time AFM images, GIWAXS orientation, and surface morphology comparison.
p004 · Results and Discussion · Figure 3 · Linked to 4 structured results
The H2O2 electrochemical reaction at the Cu-BHT film surface primarily follows a diffusion-controlled process.
Caveat: Based on linearity of reduction peak current density with the square root of scan rate.
p009 · Supporting Information · Figure S14 · Linked to 2 structured results
Face-on packing of Cu-BHT crystallites improves electron transmission from the gold electrode through the film to the film surface, contributing to high device sensitivity.
Caveat: The claim combines experimental orientation/conductivity data with a mechanistic interpretation; no direct mobility value is reported.
