NanoSight today facilitated a webinar to brief industry leaders on
the wide reaching implications of this recently announced recommended
definition and Dr Denis Koltsov, a leading international expert in
nanotechnology legislation provided his views on the legislative
landscape. NanoSight showcased its suite of nanoparticle characterisation
methods which could provide organisations a competitive edge in addressing the
measurement requirements prescribed by the European Commission.
What’s classed as a Nanomaterial in the recommended
definition?
·
A product that has more than 50% of its particle count (particles,
agglomerates and aggregates) in the range of 1 – 100 nm could essentially now
be classed as a nanomaterial and the definition only deals with particle
external size and not its material, structure or chemistry.
·
An additional classification of a nanomaterial is to demonstrate a
specific surface per unit volume of greater than 60 m2/cm3.
Koltsov points out that “the recommended definition is NOT a
regulatory or binding document and does not imply danger or risk of
nanomaterials. It affects a lot more industries that the creators of the
definition anticipated, it is not legally binding, but this type of definition
could (and will) be used by regulators.” The definition will be review in
2014 and could have ramifications for REACH.
The French are already putting the definition to use with a decree
(# 2012-232) published on 17th February 2012 stating:
·
All manufacturers, importers and distributors of nanomaterials
have to report French authorities every year
·
Minimum amount is 100g per year
Koltsov stats that Belgium and Germany are planning to follow this
example, however the USA does not seek to define nanomaterials precisely.
It is also anticipated that more member states will revert to a national legal
framework instead of relying on REACH.
The French ruling could also heavily impact Universities and importers
and exporters of materials.
The European Commission does not give a recommendation on the
measurement technique for the characterisation of nanomaterials only that size
distribution of a material should be presented as size distribution based on
the number concentration.
NanoSight offers a system that is a number-based nanoparticle
counting technique which is rapid and suitable for regular analysis on most
types of monodisperse and polydisperse samples. The system is inexpensive
to own and run and provides quick, accurate analysis in the sample’s natural
environment. Many systems are already in the market place.
NanoSight uses Nanoparticle Tracking Analysis (NTA) which can:
·
Acquire a video of the nanoparticles motion
·
Track individual particles simultaneously
·
Apply the Stokes-Einstein equation to calculate particle size
The method, which counts particles to provide an absolute
concentration measurement, is independent of mass, refractive indices and
particle material with no calibration required.
A variety of materials can be tested including, nanotubes, metal
oxides, magnetic nanoparticles, pigments, cosmetics, ceramics, proteins,
polymers, virus samples and foodstuffs.
While the French and the USA may disagree on a precise definition of
nanomaterials it is clear that the NanoSight system will offer a dynamic
platform for companies in responding to the increasing need for
characterisation.
