Optical Tweezers

The near infrared (NIR) optical tweezers experiment is built on a Nikon TE2000 epifluorescence inverted optical microscope which also has Total Internal Reflection Fluorescence (TIRF) capability. The heart of the experiment is a Mad City Labs 3-axis nanopositioning stage which has sub-nanometer resolution along all three axes.
