No, just kidding. But I like the acronym: iSCAT (for “interferometric scattering”).

Sandoghdar, et al. High-speed nanoscopic tracking of the position and orientation of a single virus. Nature Methods.

They tracked both the scattering from a virus and the fluorescence from a quantum dot attached simultaneously, with a precision of a few nanometers. And they could measure differences in the orientational tumbling of viruses of various sizes as they diffused around on a surface (on a supported lipid bilayer).

Cool.
