India ink capsule stain is used to demonstrate cell capsules through microscopic examination. This procedure is used to detect presence of encapsualted species, e.g. Cryptococcus neoformans, which causes cryptococcosis in humans.
Under the microscope, the India ink stain is used for easy visualization of the capsule in cerebral spinal fluid.  The particles of ink pigment do not enter the capsule that surrounds the spherical yeast cell, resulting in a zone of clearance or "halo" around the cells. This allows for quick and easy identification of C. neoformans.
