Line optical tweezers instrument for measuring nanoscale interactions and kinetics
16th Nov 2006, 15:52 GMT
Paul L. Biancaniello and John C. Crocker We describe an optical tweezers instrument for measuring short-ranged colloidal interactions, based on a combination of a continuous wave line optical tweezers, high speed video microscopy, and laser illumination. Our implementation can measure the separation of two nearly contacting microspheres to ... [Rev. Sci. Instrum. 77, 113702 (2006)] published Wed Nov 15, 2006.
