NanoSight
NanoSight provides a unique and powerful
characterisation capability to researchers and manufacturers of
nanoparticles.
Who they are
NanoSight provides a unique and powerful
characterisation capability to researchers and manufacturers of
nanoparticles. This ability to rapidly determine size and particle
size distribution provides a "missing link" for researchers in the
range 15nm - 500nm.
What they do
Backed by the pedigree of government
bio-defence research, and supported initially by funding from NESTA
(National Endowment for Science, Technology and the Arts),
Nanosight has developed practical instruments from new laser
illumination technology.
This remarkable technique allows individual
nanoparticles, as small as 15nm to be viewed directly in
liquids.
NanoSight's technique is proven on a range of
particles:
- Pigments and inks
- Multi-walled carbon nanotubes
- Catalysts and ceramics
- Ferritinmolecules
- Precursor chemicals in wafer fab
- Metal oxides in storage media and most other
nanoparticles
- Nanoemulsions and dispersions
Particle size is determined directly from measuring diffusion
under Brownian motion, resulting in a size distribution from
individual particles. Importantly, this new insight into the
nano-world is provided at low cost and rapidly, with no more
preparation than dilution.
