Title: NIST Develops Advanced Nanoscale Measurement and Control Techniques
Summary:
The National Institute of Standards and Technology (NIST) has developed advanced experimental and theoretical tools for measuring, analyzing, and controlling random processes in nanoscale systems. The project focuses on engineered particles in liquid environments, using optical methods for in-situ measurements of individual nanoparticles’ size, shape, mechanical properties, and transport characteristics.
Key developments include:
1. Real-time tracking and fluorescence spectroscopy techniques for monitoring nanoparticle behavior
2. Optimal diffusion coefficient estimation methods for understanding nanoparticle motion in liquids
3. Nanoparticle tracking for fluidic self-assembly applications
4. Software tools for modeling and analyzing noisy data
The project aims to exploit fluctuations in nanoparticle behavior to determine their properties and dynamics in their native liquid environment. This research has led to several publications and advances in nanoscale measurement and control techniques.
