Measuring nanometer-sized particles with dynamic light-scattering techniques
The development of dynamic light-scattering technology is providing accurate sizing of ultrafine particles from 3 to 6,000 nanometers. After discussing the growing popularity of nanosized particles, this article describes challenges in measuring such small particles and how two methods of dynamic light scattering overcome these challenges. The final section covers applications for these sizing techniques.
It may be a well-worn phrase, but good things do come in small packages. The ultrafine particle sizes of today's advanced materials signal a revolution in controlling material characteristics and performance.
