A General Strategyfor Photostable and BioconjugatablePentamethine Cyanine Fluorophores

Abstract Pentamethine cyanine (Cy5) fluorophores are widely used in biological imaging but are often limited by rapid photobleaching under prolonged illumination and oxidative conditions. Here, we report a general strategy to enhance the photostability of pentamethine cyanines th...
