More than that, her optical tweezers can isolate the bacteria to be studied, handling them without killing them.
This developing system is called an Optical Tweezers (OT) and it uses a focused laser beam and a camera to move and track microscopic objects.
The use of optical tweezers in order to measure the force in objects at nanometirc scale can be an interesting idea for the researchers in all fields, including biosciences.
This maximizes the capability of the optical tweezers.
Optical tweezers can be used in an elegant immunoassay strategy, as described in this issue [7].
Four other scientists have received the Rank Prize in Optoelectronics for research done at Bell Labs: Linn Mollenauer and Akira Hasegawa in 1991, for their work on soliton propagation in optical fiber, and Arthur Ashkin and Joseph Dziedzic in 1992, for work on optical tweezers, using focused laser light to trap and manipulate live biological entities, like viruses.
With optical tweezers, a laser method that enables them to manipulate individual DNA strands, the researchers tugged and twisted one strand at a time, deforming it in various ways.
Light pressure forces have served as the foundation for many cutting-edge research fields, such as work with optical tweezers, trapping of neutral particles and Bose-Einstein condensation.
Then, measurements at the fine scale of the complex fluids using confocal microscopy and optical tweezers will give access to the flow behaviour at the local scale.
Therefore, optical tweezers cannot grasp super-small objects like individual proteins, which are only a couple of nanometers in diameter.
JDSU's unique technology combination is opening the door to emerging applications in laser projection, optical tweezers, confocal microscopy, and high density optical data storage for example-that particularly value high-precision solutions," said Barry Weitzenberg, general manager of JDSU's Advanced Optical Technologies, Custom Optics Product Group.
