Nano-objects characterisation platform
The equipment on this platform can be used to :
– characterise all types of nano-objects formulated within the research teams: size, distribution, zeta potential, etc.
– study the assembly mechanisms of these objects
– assess their stability in different environments
Operating procedures and training
The platform is located in room 2845.
You must follow the training course before using any equipment for the first time !
Equipment
-
Zetasizer Nano ZS (Malvern Panalytical)
-
Zetasizer Ultra (Malvern Panalytical)
-
Nanosight LM10 (Malvern Panalytical)
The instruments in this platform enable the analysis of nano-objects using Dynamic Light Scattering (DLS) techniques.
The Zetasizer range allows determination of the size distribution of formulated nano-objects. The Zetasizer Ultra additionally performs measurements at multiple angles (MADLS), improving resolution between different populations potentially present within the same sample, and providing nanoparticle concentration for each population. Moreover, it is equipped with a fluorescence filter and both horizontal and vertical polarizers.
Furthermore, both Zetasizer instruments enable Electrophoretic Light Scattering (ELS), allowing measurement of electrophoretic mobility and zeta potential of nano-objects.
In contrast, the Nanosight LM10 uses Nanoparticle Tracking Analysis (NTA), a method that directly visualizes individual scattering nano-objects and provides their size distribution and concentration.
