1 · 1. Introduction
Author InterpretationMedium supportMaterial Comparison
The review argues that MOFs offer broader surface-area, functionality and structural-flexibility advantages over COFs and polymers for urinary-biomarker sensors.
Evidence basis: review_reasoning

The review uses MoS2 on aluminium foil as a non-MOF comparison where metallic 1T phase improves conductivity and uric-acid detection sensitivity relative to semiconducting 2H phase.

The review states that documented COFs lack the redox-responsive features needed for sensing applications, whereas MOFs can provide redox-active and functional nodes.

Reusability is presented as an unresolved challenge because MOFs can structurally collapse or lose functionality under temperature, pressure and humidity cycling.
Evidence basis: multi_reference
Caveat: This is a broad durability caveat rather than a urine-specific failure analysis.

Consensus SummaryHigh supportCaveat
The review treats MOF stability as a limiting condition for analytical use and links it to hard/soft acid-base chemistry, linker pKa, humidity and framework interpenetration.

Conductive MOFs can support through-bond, through-plane, through-space, redox-hopping and guest-mediated pathways, and pathway understanding is presented as necessary for designing sensor function.
Evidence basis: multi_reference
Caveat: Different mechanisms may coexist; the review is conceptual rather than mechanistically resolving each example.
