Taxonomy: Technique Branch / Method. Workflows sit above the mechanism and technique branches rather than replacing them.

Summary

Measurements of domain mobility indicated the presence of 120 nm wide ordered and 40 nm wide disordered domains.

Implementation Constraints

cofactor dependency: cofactor requirement unknownencoding mode: genetically encodedimplementation constraint: context specific validationoperating role: sensorswitch architecture: recruitment

It requires a membrane system in which domain mobility can be measured; the abstract does not specify the exact instrumentation or model used.; requires measurable domain mobility in the membrane system

It does not directly image the full domain structure at the inferred nanometer scale in the abstract.; domain sizes are inferred from mobility rather than directly resolved by light microscopy
