A light tube that can grab, orient and record the movements of tiny, agile unicellular organisms may soon help scientists better understand bacterial infectious diseases. The new light-scanning optical trap developed by scientists at the Department of Microsystems Engineering at the University of Freiburg traps and scans tiny elongated bacteria with the help of a quickly moving focused laser beam. The beam exerts an equally distributed force over the entire bacterium, which constantly changes its complex form. Simultaneously, the team was able to record the trapped bacterium’s...Read full article
