Nanosight has announced that the UK's National Physical Laboratory (NPL) uses the LM-10 system for its studies in nanoparticle characterisation.
The NPL routinely looks at emerging techniques to evaluate their performance for the quantitative characterisation of nanomaterials.
Nanoparticles are a current area of intense scientific research, as they are a bridge between atomic and bulk structures.
The NPL is coordinating a network of European national metrology institutes to provide new traceable standards and procedures to determine the size, shape and distribution of nanoparticles with an accuracy of better than 1nm.
Many methods, including Electron Microscopy (SEM and TEM), Dynamic Light Scattering (DLS), Nanoparticle Tracking Analysis (NTA) and Atomic Force Microscopy (AFM), are being used to investigate the particles' size and shape, as well as their physical properties.
One of the tasks of Dr Alexandre Cuenat as part of the materials team at the NPL is measuring and modelling of materials interactions at the nanoscale.
Each measurement technique has specific applications and, for an organization like such as the NPL, it is important to understand all of them, including their advantages and limitations.
For Dr Cuenat, working with Nanosight's NTA methodology to study nanoparticles in liquids shows particular bonuses compared with other techniques.
