Camera Particle Tracking Technology Enhances Elliot Scientific Optical Tweezer Systems
(Nanowerk News) Camera Particle Tracking technology (CPT) is a
technique developed at Glasgow University to enhance 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.
Laser 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.
Current systems can only measure the force exerted on one particle, but the CPT
technology will enable the collection of data from multiple particles at a
higher rate. This will allow for:
Convenient trap calibration by thermal analysis.
Improved trap stiffness measurements
Multiple particle tracking within microfluidic channels
Orbital angular momentum measurements
Viscosity measurements at several points simultaneously
In December 2010, following selection by the University of Glasgow, Elliot
Scientific is 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.
Elliot Scientific will demonstrate their first system incorporating CPT
technology at the American Biophysical Society Annual Meeting, Baltimore, in
