Nanoparticle Tracking Analysis
A unique method of visualising and analysing particles in liquid that relates the rate of Brownian motion to particle size.
- An easy-to-use, reproducible platform for nanoparticle characterization
- Simple and direct qualitative view
- Quantitative estimation of particle size and size distribution
- Limitations: analysis of 10nm particles is only possible for particles with a high refractive index such as gold and silver; the upper size limit is restricted by the limited Brownian motion - at sizes ~1µm particles move very slowly, significantly reducing the accuracy of the technique
