Published Workflows

Objective: Measure and interpret nanoparticle surface inhomogeneity by combining single-particle 3D super-resolution imaging with probabilistic localization modeling.

Why it works: The source summary indicates that 3D-dSTORM provides localization data and the probabilistic maximum-likelihood framework converts those stochastic observations into estimated fluorophore positions on nanoparticle surfaces.

Implementation Constraints

cofactor dependency: cofactor requirement unknownencoding mode: genetically encodedimplementation constraint: context specific validationoperating role: sensor

The source summary indicates a 3D-dSTORM imaging setup and fluorophore-labeled nanoparticles are required. Astigmatism-based 3D localization is specifically mentioned.; requires fluorophore labeling; requires super-resolution microscopy setup

Independent follow-up evidence is still limited. Validation breadth across biological contexts is still narrow. Independent reuse still looks limited, so the evidence base may be fragile. No canonical validation observations are stored yet, so context-specific performance remains under-specified.
