Introduction:
The rapid in vitro measurement of multiple physical parameters such as size, concentration, surface charge, and phenotype characteristics is the special feature of the Particle Metrix ZetaView®.
Nanoparticle Tracking Analysis (NTA) captures the Brownian motion of each particle in the video. Based on the different diffusion movements of large and small particles in the surrounding liquid, the hydrodynamic diameter of the particles is determined. Furthermore, the charge state of the particle surface (zeta potential) can be measured via the movement of the particles in an applied electric field.
Function (application):
1. For the analysis of size, concentration, fluorescence, electrophoretic mobility and sub-populations of individual nanoparticles.
2. Biological nanoparticles:Bionanoparticles、F-labeled bioNP、Liposomes + Micelles、Drug delivery、Protein agglomeration Virus like particles (VLP)、Virus samples / Viral titer、Extracellular vesicles (EV)、Emulsions Polymers、Nanometals、Nanobubbles、Irregular particles、Quantum dots
