Up to now, if scientists wanted to study blood cells, algae, or bacteria under the microscope, they had to mount these cells on a substrate such as a glass slide.Physicists at Bielefeld and Frankfurt Universities have developed a method that traps biological cells with a laser beam enabling them to study them at very high resolutions.In science fiction books and films, the principle is known as the 'tractor beam'.

One of the problems with imaging living biological cells is that they don't want to be held still.Or, more accurately, they don't want to be held to a surface like a microscope slide.Prepping and fixing the cells changes them irrevocably, altering whatever a scientist was trying to observe.

BIELEFELD, Germany, Dec. 13 (UPI) -- Studying bacterial cells and other cell cultures at high resolutions is now much easier thanks to a team of researchers from Germany.Scientists at Bielefeld University have found a way to trap bacteria with a laser beam, simplifying the process of imaging cells with powerful microscopes.Typically, scientists affix cells to a substrate before placing them under the lens of a microscope.
