Biological Activity

[Description]:

Methyl blue belongs to the group of triaminotriphenylmethane dyes. Methyl blue is widely used as antiseptic dye in polychrome staining method and has applications in histological and microbiological staining solutions. Methyl blue has been used as a model to study the effect of various catalysts on photodegradation of dyes[1][2].
