NanoSight Holds First European Users Meeting on Nanoparticle Characterization
(Nanowerk News) NanoSight, world-leading manufacturers of unique nanoparticle characterization technology, together with distributor partners Schaefer Technologie, have recently held a meeting of users of their successful range of nanoparticle tracking analysis instruments in Langen, Germany.
More than thirty NanoSight users came to a sunny Langen near Frankfurt to share their experiences in developing test methods for nanoparticle measurement and characterization. The meeting provided an excellent opportunity to present new data using nanoparticle tracking analysis, NTA.
Delegates at NanoSight's European Users' Meeting
Invited speakers from leading national research laboratories and universities gave papers on a broad range of topics. These ranged from the study of the electrophoretic mobility of nanoparticles generated by laser ablation in liquids from the Laser Zentrum in Hannover to qualitative and quantitative analysis of nanomaterials in environmental samples form the University of Koblenz-Landau. Nanotoxicology was discussed in a talk on starch-coated magnetic nanoparticles with pendant chelating agents given by Holger Stephan of the Forschungszentrum Dresden-Rossendorf. The ground-breaking work of Wim Jiskoot's research group from Leiden University, the Netherlands on using NTA for the measurement of nanoparticle and protein aggregates was also reported.
The meeting enabled users to bring their instruments with them for service and software upgrades carried out by NanoSight support staff from the UK. Led by founder and CTO, Bob Carr, users further learned about the use of fluorescence detection to study nanoparticles and concentration determination methods in vaccine applications.
To build on this success NanoSight will be holding more users' meetings worldwide. The next is scheduled in the USA in Washington DC. More information about nanoparticle characterization using nanoparticle tracking analysis is available by visiting the company's website (www.nanosight.com) where visitors may also register for the latest issue of NanoTrail, the company's electronic newsletter.
NanoSight Limited, of Salisbury, UK, provides unique nanoparticle characterization technology. "Nanoparticle Tracking Analysis" (NTA) detects and visualizes populations of nanoparticles in liquids down to 10nm (material dependent) and measures the size of each particle from direct observations of diffusion. This particle-by-particle methodology goes beyond traditional light scattering techniques such as Dynamic Light Scattering (DLS), or Photon Correlation Spectroscopy (PCS), in providing high-resolution particle size distributions. Additionally NanoSight measures concentration and validates all data with video of particles moving under Brownian motion.
This characterization information is highly informative in understanding the more complex suspensions in biological systems, hence its wide application in development of drug delivery systems, viral vaccines, the study of toxicology of nanoparticles and their environmental fate and in biomarker detection. This real-time data also provides insight into the kinetics of protein aggregation and other time-dependent phenomena in a quantitative manner, at deeply sub-micron sizes.
NanoSight has more than 250 systems installed worldwide with users including BASF, BP, GlaxoSmithKline, Novartis, 3M Corp., Roche, Solvay and Unilever together with many universities and research institutes. There are currently 100+ third party papers citing NanoSight results, with this reference base growing very rapidly as NanoSight consolidates its key contribution to nanoparticle characterization.
