Laser Tweezers: Reach Out and Grab Bacteria!

Visit our lab to see how we utilize "optical tweezers" that use lasers to reach out, grab, and manipulate individual swimming cells. It is a very interactive, hands-on activity with video game-like joystick action. We invite the public to use our microscope and try to catch and grab hold of live cells and interact with them. We will learn about cells from the bottom up, and about the latest in technology that allows us to see and interact with individual cells and molecules.
