  • Title: Twinkle, twinkle little star: photoswitchable fluorophores for super-resolution imaging.
    Author: Chozinski TJ, Gagnon LA, Vaughan JC.
    Journal: FEBS Lett; 2014 Oct 01; 588(19):3603-12. PubMed ID: 25010263.
    Abstract:
    Photoswitchable fluorescent probes are key elements of newly developed super-resolution fluorescence microscopy techniques that enable far-field interrogation of biological systems with a resolution of 50 nm or better. In contrast to most conventional fluorescence imaging techniques, the performance achievable by most super-resolution techniques is critically impacted by the photoswitching properties of the fluorophores. Here we review photoswitchable fluorophores for super-resolution imaging with discussion of the fundamental principles involved, a focus on practical implementation with available tools, and an outlook on future directions.
