Particle and Surface Sciences are pleased to announce the launch of NanoSight Technology. NanoSight will provide a new range of products to enhance and broaden the range of particle characterization systems already offered by Particle and Surface Sciences Australia.
NanoSight provides a unique technology to visualise and size nano-scale particles in liquid down to 10 nm with little preparation and at low cost. Based on a fundamental understanding of existing particle sizing techniques, the NanoSight technology has been developed into a unique and exciting instrument for nanoparticle sizing, available as both a research instrument and in a bench-top format.
The Nanoparticle Tracking Analysis (NTA) technique is based on laser light scattering microscopy. The instruments can visualise and dynamically size populations of particles in a liquid on an individual basis in the particle size range of 10 nm – 1000 nm (dependent on material). The Brownian motion of each and every particle (which appear as point scatterers) is tracked separately but simultaneously using a CCD camera, from which a high-resolution plot of the particle size distribution profile (and changes therein in time) is obtained.
This particle-by-particle approach avoids the averaging assumptions of Photon Correlation Spectroscopy (PCS, also known as Dynamic Light Scattering, DLS) and provides a unique image, going beyond PCS in assessing polydisperse systems. The technique uniquely allows the user a simple and direct qualitative view of the sample under analysis (perhaps to validate data obtained from other techniques such as PCS) and from which an independent quantitative estimation of sample size, size distribution and concentration can be immediately obtained. Sample pre-treatment is minimal, requiring only dilution with a suitable solvent to an acceptable concentration range (between 108 and 109 particles per ml depending on sample type). All particle types can be measured and in any solvent type providing that the particles scatter sufficient light to be visible (i.e. are not index matched).
The NanoSight NTA technique represents an attractive alternative or complement to higher cost and more established methods of nanoparticle analysis such as photon correlation spectroscopy or electron microscopy that are currently employed in a wide range of technical and scientific sectors.
Particle & Surface Sciences () also offer a wide-ranging programme of support solutions, including installation and service of all instruments by factory-trained technicians, an Analytical Laboratory and a Sales Department to assist with your enquiries. PsSâ„¢ will be running a series of seminars across Australia during the month of February 2009. Please visit the PsSâ„¢ website for more information on the locations.
