Open a family to keep every result attached to its sample, method and conditions.
Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The Apt/Au/Cu-THQ/GCE aptasensor detects LPS over 1 fg/mL to 100 pg/mL with a 0.15 fg/mL LOD.
Caveat: Analytical performance is based on DPV calibration under the reported assay conditions.
8 · LPS detection performance of Apt/Au/Cu-THQ/GCE · Figure 4A,B · Linked to 4 structured results
The aptasensor can detect LPS in diluted and clinical serum samples with acceptable recovery and agreement with the WB-80 standard method.
Caveat: Clinical comparison includes only three serum samples.
9 · Serum sample detection · Tables 1-2 · Linked to 6 structured results
The rendered SI surrogate enabled extraction of SI table bodies and plotted labels, resolving the prior missing-SI request; one blank rendered page did not affect extractable values.
Caveat: Some optimisation bar heights remain visual estimates because raw numeric data were not supplied.
3-21 · Supplementary Materials · Tables S1-S3; Figures S1-S14 · Linked to 3 structured results
Cu-THQ provides a superior supporting surface for abundant, uniform, nanoflower-like Au deposition.
Caveat: EDS table labels distinguish mass-normalised and atom percentages; main text appears to describe atom percentages as mass percentages.
6 · Preparation and characterization of Au/2D-MOF/GCE · Figure 2; Figures S8-S9 · Linked to 5 structured results
Cu-THQ exhibits significantly higher electrical conductivity than Cu-TCPP based on lower Rct for Cu-THQ/GCE.
Caveat: Conductivity is inferred from EIS charge-transfer resistance of MOF-coated electrodes rather than a direct four-probe conductivity measurement.
5 · Characterization of the synthesized 2D Cu-MOF nanosheets · Figure S3 · Linked to 2 structured results
Au/Cu-THQ/GCE has superior electron-transfer and electrochemical activity relative to Au/Cu-TCPP/GCE, Au/GCE and bare GCE.
Caveat: Evidence is electrochemical (CV/EIS/DPV) rather than direct bulk transport measurement.
