This self-serve instrument provides a rapid measurement such as size, concentration or the charge state of the surface (zeta potential) of biological nanoparticles including exosomes, extracellular vesicles (EVs), or viruses by capturing the Brownian motion of each individual particle.

The expert staff at NYU Langone’s Cytometry and Cell Sorting Laboratory provides researchers with training on and access to our ZetaView Nanoparticle Tracking Analyzer.

ZetaView Selection of Fluorophores

The ZetaView is equipped with 4 different lasers: 405, 488, 520 and 640/660 nm. The choice of the fluorophores that will be used with the fluorescence nanoparticle tracking analyzer (F-NTA) should be made according to the excitation wavelengths, the photostability and the brightness of the fluorophore.

The table below lists fluorophores that have shown characteristics for detection when used with F-NTA:
