Eosin Y is a popular dye used in cosmetics and pharmaceuticals as well as a tissue and vital stain. It is used as a counterstain to hematoxylin in haematoxylin and eosin (H&E) staining, one of the principal stains in histology for cancer diagnosis. It stains proteins in the cytoplasm along with collagen and muscle fibers. In other applications, when combined with silica nanoparticles it can be part of a fluorophore for a peroxyoxalate chemiluminescence system.
