Water‐Soluble Monofunctional Perylene and Terrylene Dyes: Powerful Labels for Single‐Enzyme Tracking

Abstract

All in one: Exceptionally photostable, highly fluorescent, water-soluble, and monofunctional perylene and terrylene dyes bearing reactive groups for covalent attachment to biomolecules have been synthesized (see picture). Single-molecule enzyme tracking revealed that single enzymes could be visualized even on a substrate with fluorescent background.
