NanoSight Ltd is a company that designs and manufactures instruments for the scientific analysis of nanoparticles that are between approximately ten nanometers (nm) and one micron (μm) in diameter. The company was founded in 2003 by Bob Carr and John Knowles to further develop a technique Bob Carr had invented to visualize nanoparticles suspended in liquid. The company has since developed the technique of Nanoparticle Tracking Analysis (NTA), and they produce a series of instruments to count, size and visualize nanoparticles in liquid suspension using this patented technology. NanoSight has 25 employees in the UK and has received several awards and recognitions.〔(A Queen's Award for Enterprise for International Trade 2012 has been awarded to NanoSight. ) ''Nanotechnology Now'', May 1, 2012.〕 More than 450 instruments had been sold as of 2012. The technology has been cited in over 1300 scientific publications, presentations and reports. NanoSight was acquired by Malvern Instruments on the 30th September 2013.〔(【引用サイトリンク】url=http://www.malvern.com/malvern/pr.nsf/id/pr2795 )〕 ==Product overview== NanoSight develops and produces instruments that visualize, characterize and measure small particles in suspension. Detected particles may be as small as 10 nm in diameter, depending on composition. NanoSight instruments can analyze particle size, concentration, aggregation, and zeta potential. An optional fluorescence mode, employing an optical filter, allows speciation of fluorescently labeled particles. Each instrument comprises a scientific camera, a microscope,〔 *Bob Carr, Patrick Hole, Andrew Malloy, Jonathan Smith, Andrew Weld and Jeremy Warren (2008) "The real-time, simultaneous analysis of nanoparticle size, zeta potential, count, asymmetry and fluorescence in liquids", Particles 2008; Particle Synthesis, Characterization, and Particle-Based Advanced Materials, 10–13 May 2008, Wyndham Orlando Resort, Orlando, Florida.〕〔 *Warren, J and Carr, R (2007), "Application of Nanoparticle Tracking Analysis to BioNano Systems", 2nd International Congress of Nanobiotechnology & Nanomedicine (NanoBio2007), San Francisco, USA, June 19, 2007.〕 and a sample viewing unit (LM12 or LM14). The viewing unit uses a laser diode to illuminate particles in liquid suspension that are held within or advanced through a flow chamber within the unit. The instrument is used in conjunction with a computer control unit that runs a custom-designed Nanoparticle Tracking Analysis (NTA) software package. NTA analyzes videos captured using the instrument, giving a particle size distribution and particle count based upon tracking of each particle's Brownian motion. Tracking is carried out for all particles in the laser scattering volume to produce a particle size distribution using the Stokes-Einstein equation, relating the Brownian motion of a particle to a sphere-equivalent hydrodynamic radius. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「NanoSight」の詳細全文を読む スポンサード リンク
