"rotation of nanoscale rotors such as polystyrene-gold Janus particles using dark-field optical microscopy... live cells including live strains of fungi, bacteria and human cells in cell culture media containing ions... suited for rotors with complex architectures including out-of-plane rotation of particle dimers, trimers, and hexamers. Using the method, Ding et al envision accurate regulation of the rotor and laser beam to accomplish 3D profiling of biological cells and synthetic particles of high resolution"
