Photoactivatable fluorophores
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 ... WebPhotoactivatable fluorophores switch from a nonemissive to an emissive state upon illumination at an activating wavelength and then emit after irradiation at an exciting …
