Bioluminescence is a popular modality for imaging in living organisms. The platform relies on enzymatically (luciferase) generated light via the oxidation of small molecule luciferins. Since no external needed photon production, there are concerns with background autofluorescence or photobleaching over time-features that have historically limited other optical readouts. thus routinely used longitudinal tracking across whole animals. Applications brain, though, been more challenging due to lack sufficiently bioavailable, bright, and easily multiplexed probes.
