Multicolor 3D Orbital Tracking
Small, Volume 19, Issue 17, April 26, 2023., 2023 Feedback‐based single‐particle tracking (SPT) is a powerful technique for investigating particle behavior with very high spatiotemporal resolution. The ability to follow different species and their interactions independently adds a new dimension to the information available from SPT.

On the Mechanisms of Cyanine Fluorophore Photostabilization [PDF]
The Journal of Physical Chemistry Letters, 2012 Cyanine fluorophores exhibit greatly improved photostability when covalently linked to stabilizers, such as cyclooctatetraene (COT), nitrobenzyl alcohol (NBA) or Trolox. However, the mechanism by which photostabilization is mediated has yet to be determined.
