E4500 Camera Particle Tracking Option: Multiple Particle/Force Measurements - Standalone or Integrated Systems


Enhances quantitative measurement capability in research involving optical trapping   

Optical trapping is a difficult and multi-faceted technique, involving lasers, microscopes, imaging systems, specialist software and complex opto-mechanical design.
It can take one to two years for a post-doc student to DIY build and calibrate a laser tweezer before they can begin meaningful experiments. Elliot Scientific turnkey optical trapping systems work "straight out the box," allowing research to begin from day one.
Current systems can only measure the force exerted on one particle, but CPT technology enables the collection of data from multiple particles at a higher rate. This allows for:

  • Convenient trap calibration by thermal analysis
  • Improved trap stiffness measurements
  • Multiple particle tracking within microfluidic channels
  • Viscosity measurements at several points simultaneously

Optical Tweezers have become an invaluable tool for measuring and exerting forces in the microscopic world. The picoNewton forces that light can exert on minuscule particles have empowered scientists, particularly those in biomedicine, enabling them to perform important studies on single molecules, cells and colloids without inflicting damage.

The E4500 Optical Tweezers with Camera Particle Tracking (CPT) was publically demnostrated for the first time at the Biophysical 55 exhibition and conference in Baltimore, USA on March 6th 2011.

In December 2010, following selection by the University of Glasgow, Elliot Scientific was the first company to benefit from the University's Easy Access IP initiative, a scheme designed to freely transfer some of the University's technical, scientific and medical intellectual property to research and industry for the benefit of all.
