Malvern NanoSight NS300 for counting, sizing and visualising individual nanoparticles

Sunday, 01 March, 2020 | Supplied by: ATA Scientific Pty Ltd


Malvern NanoSight NS300 employs the technique of Nanoparticle Tracking Analysis (NTA) to visualise, size and count individual nanoparticles in a liquid suspension in real time, with the feature of direct visualisation of the suspension designed to give the user extra confidence.

Like Dynamic Light Scattering (DLS), NTA operates on the principle of light scattering to determine particle size by assuming Brownian motion of nanoparticles. But while DLS measures fluctuations in the scattered light intensity, NTA tracks individual particle movements. This provides high-resolution measurements, and thus higher demands can be placed on its precision.

The product is suitable for polydispersed systems ranging from 10–30 nm up to 1–2 µm in size (depending on particle type) and is particularly useful for very dilute dispersions. Additional parameters allow users to acquire information on nanoparticle concentration, protein aggregation and viscosity, and also to visualise and analyse fluorescently labelled particles.

Malvern NanoSight is designed to offer higher resolution when compared to similar systems available while also being fast and easy to use, complementing existing methods of nanoparticle analysis. It can be used to measure a plethora of sample types, such as extracellular vesicles (including exosomes), viruses, protein aggregates and drug delivery particles (including liposomes and polymeric particles), as well as environmental and nanotoxicology samples.
