Luminescent "Crystalline" Particles: An Organized Subcellular Bioluminescent System

Abstract
A new type of intracellular biological particle which is functional in light emission has been discovered and isolated. As seen with the electron microscope it resembles a crystal; moreover, its high degree of birefringence suggests crystallinity. Isolated particles can be caused to emit a luminescent flash that resembles the flash emitted by the dinoflagellate, Gonyaulax polyedra. The particles are referred to as "scintillons".
