Rose bengale, also known as rosaniline or basic rosaniline, is a triarylmethane dye exhibiting a vibrant magenta hue. Its significance stems from its historical role as a biological stain, particularly in microbiology for visualizing cellular structures like nuclei and bacteria, and in histology for demonstrating elastic fibers. Beyond its staining capabilities, rose bengale finds application in photodynamic therapy (PDT) due to its photosensitizing properties, generating reactive oxygen species upon light exposure, offering potential in cancer treatment and antimicrobial applications. Research explores its use in dye-sensitized solar cells and as a pH indicator. Understanding its chemical properties, spectral characteristics, and interactions with biological tissues is crucial for advancements in biomedical research, analytical chemistry, and materials science. Related areas of study include xanthene dyes, biological staining techniques, photochemistry, and reactive oxygen species generation.
