Methylene blue is a monoamine oxidase inhibitor (MAOI) [39] and, if infused intravenously at doses exceeding 5 mg/kg, may result in serotonin syndrome if combined with any selective serotonin reuptake inhibitors (SSRIs) or other serotonergic drugs (e.g., duloxetine, sibutramine, venlafaxine, clomipramine, imipramine).

Methyl blue is a chemical compound with the molecular formula C 37 H 27 N 3 Na 2 O 9 S 3.It is used as a stain in histology, [1] and stains collagen blue in tissue sections. It can be used in some differential staining techniques such as Mallory's trichrome stain and Gömöri trichrome stain, and can be used to mediate electron transfer in microbial fuel cells.
Blue nucleus, blue cytoplasm, red granules Basophils: Purple/dark blue nucleus, violet granules Monocyte: Violet nucleus, light blue cytoplasm Bacteria and fungi: Dark blue Cytoplasm, collagen and muscle: Various shades of pink, orange, yellow and blue [11] Spermatozoa: Light blue acrosomal region, dark blue post-acrosomal region [8]
After the Ziehl-Neelsen staining procedure using carbol fuchsin, acid-fast bacteria are observable as vivid red or pink rods set against a blue or green background, depending on the specific counterstain used, such as methylene blue or malachite green, respectively. Non-acid-fast bacteria and other cellular structures will be colored by the ...
The original sources of azure B (one of the oxidation products of methylene blue) were from polychromed methylene blue solutions, which were treated with oxidizing agents or allowed to naturally age in the case of Romanowsky. [3] [13] Ernst Malachowsky in 1891 was the first to purposely polychrome methylene blue for use in a Romanowsky-type stain.
New methylene blue (also NMB) [clarify] is an organic compound of the thiazine class of heterocycles. It is used as a stain and as an antimicrobial agent. It is classified as an azine dye, and the chromophore is a cation, the anion is often unspecified.

The synthetic dye methylene blue, containing the structure, was described in 1876. Many water-soluble phenothiazine derivatives, such as methylene blue, methylene green, thionine, and others, can be electropolymerized into conductive polymers used as electrocatalysts for NADH oxidation in enzymatic biosensors and biofuel cells.
