Description

Rose Bengal is a reactive dye that has been used as a model system for understanding the chemical reactions of phase transitions. It is a member of Group P2 of the periodic table, and is therefore considered to be an inorganic compound. Rose Bengal undergoes an oxidation-reduction reaction with dinucleotide phosphate, which leads to its colour change from red to blue. The reaction mechanism can be seen in the following diagram:

There are many biological properties associated with Rose Bengal. It has been shown to have cytotoxic effects on human leukemia HL-60 cells, and it also has a strong affinity for bacterial DNA. Rose Bengal has also been used as a diagnostic agent for gram-positive bacteria, such as Staphylococcus aureus and Streptococcus pyogenes, due to its ability to bind to these species' cell walls.
