LGC, the UK’s designated National Measurement Institute for chemical and bioanalytical measurement, is developing a range of nanoparticle reference materials to enable the development of traceable methods for improved in vitro toxicity measurement for safety assessment.
These will be assessed for their physical and chemical properties in an in vitro biological matrix. These materials will be based on the high quality nanoparticles produced by the EU-Joint Research Centre (JRC) which have undergone extensive physical characterization in the dry-powder form. LGC are carrying out the characterization work using a unique combination of Nanoparticle Tracking Analysis , with field flow fractionation coupled to inductively coupled plasma mass spectrometry (FFF-ICPMS), allowing complex suspensions of nanomaterials to be characterized for their size, size distribution, charge, concentration, dissolution and elemental composition.
