Particle Tracking: “One Step at a Time”

Determining the size and distribution of colloidal systems with nanometer-scale precision is crucial for various nanobiotechnology applications. We focus on refining the data analysis method associated with nanoparticle tracking analysis (NTA), which measures the diffusion coefficient of particles in a sample in order to determine their size distribution.
