Size resolution limitation on Dynamic Light Scattering

Click For Summary
SUMMARY

The current limiting resolution for Dynamic Light Scattering (DLS) remains at 1nm, as confirmed by multiple sources, including a six-year-old article from AZoNano and a discussion on ResearchGate. Despite inquiries into potential advancements in DLS technology, no updates or improvements in resolution have been reported. The technique is primarily experimental, with users like @ZapperZ indicating a lack of experience in DLS specifically.

PREREQUISITES
  • Understanding of Dynamic Light Scattering (DLS)
  • Familiarity with light scattering principles
  • Knowledge of experimental techniques in spectroscopy
  • Basic concepts of measurement limits in scientific instrumentation
NEXT STEPS
  • Research advancements in DLS technology and potential improvements in resolution
  • Explore alternative techniques for particle size measurement
  • Learn about the principles of light scattering in detail
  • Investigate the applications of DLS in various scientific fields
USEFUL FOR

Researchers, scientists, and laboratory technicians involved in particle characterization and those interested in the limitations and advancements of Dynamic Light Scattering technology.

I have been looking online and it is stated to be 1nm, but these are posts around 6 years old:

https://www.researchgate.net/post/Whats_the_measurement_limit_of_dynamic_light_scattering

I am wondering if the limiting resolution has improved on DLS or it has stayed the same.

@ZapperZ do you know?

No, sorry. This is an experimental technique that I've never used. All the light scattering experiments that I've done are for spectroscopy, not imaging or spatial resolution.
