technology
Nanoparticle tracking analysis (NTA)
Single-particle video microscopy that tracks Brownian motion to report both size and true particle concentration, standard for extracellular vesicles and viral vectors.
Where it's used
Exosome therapy & extracellular vesicles
Cell-derived nanoscale vesicles (30-150 nm) used as native regenerative-medicine agents or engineered as biocompatible drug-delivery vehicles for RNA, protein and gene-editing cargo, crossing biological barriers artificial lipid nanoparticles cannot.
Particle size and zeta potential analyzers (DLS, NTA)
Bench-top instruments that size and charge-characterize particles from nanometers to millimeters — dynamic light scattering, laser diffraction, nanoparticle tracking and multi-angle light scattering — the standard release and formulation-R&D toolkit for lipid nanoparticles, biologics aggregates, extracellular vesicles and industrial powders.
