A technique of detecting the rolling and spinning of half-coated nanoparticles using interference ring patterns of the fluorescence has been demonstrated. Using the unique ability to measure nanoparticle rotations in multiple degrees of freedom, we are able to determine the orientation of a moving nanoparticle in real time. Ultimately, the detailed knowledge of the rotational behavior of half-coated nanoparticles is expected to produce physical insight of nano biomechanical systems. © 2004 American Institute of Physics.
