Biologists use optical tweezers to manipulate micron

-

sized objects using a beam of light. In this technique, a laser beam is focused to a very small

-

diameter spot. Because small particles are attracted to regions of high light intensity, the focused beam can be used to "grab" onto particles and manipulate them for various experiments. In one experiment, a

10

mWmW laser beam is focused to a spot that has a diameter of

0.62
