The article presents information on a system that tracks moving nanoparticles in three dimensions. The system also provides spectroscopic measurements. The apparatus has been described by the researchers led by Haw Yang at the University of California, Berkeley, California and Lawrence Berkeley National Laboratory. The researchers demonstrated the system by monitoring an individual gold nanoparticle in solution. They used a green laser beam to collect the spectroscopic information. The system is noninvasive and has a spatial resolution of more than 210 nanometer.
