Photoactivatable fluorophores
WebAdditionally, targeting ligands can be incorporated in the resulting photoactivatable fluorophores (PAFs) to label selected subcellular components in live cells. Indeed, photoactivatable BODIPYs have already allowed the sub-diffraction imaging of diverse cellular substructures in live cells using PALM and can evolve into invaluable analytical ... WebMay 11, 2024 · A photoactivatable fluorophore serves as the donor, which can be converted into an activated form by a laser pulse. Unbound activated fluorophores quickly diffuse out from the glass surface and are diluted by non-activated molecules, whereas activated fluorophores attached onto the microscope slide are continuously excited by the …

WebFeb 27, 2024 · Photoactivatable fluorophores provide the opportunity to switch fluorescence on exclusively in a selected area within a sample of interest at a precise interval of time. Such a level of spatiotemporal fluorescence control enables the implementation of … WebFeb 27, 2024 · Photoactivatable fluorophores switch from a nonemissive to an emissive state upon illumination at an activating wavelength and then emit after irradiation at an exciting wavelength.
WebFluorophores emit a limited number of photons before bleaching, so it's important to collect as many as possible. While we can sometimes compensate for poor excitation efficiency simply by increasing the illumination light power (at the potential cost of phototoxicity), the same cannot be said for poor collection efficiency: those lost emission ...
