Luminol

) is a versatile
chemical
that exhibits
chemiluminescence
, with a striking blue glow, when mixed with an appropriate
oxidizing agent
. It is a white to slightly yellow crystalline solid that is soluble in most polar organic solvents, but insoluble in water.
Luminol is used by
forensic
investigators to detect trace amounts of
blood
left at
crime scenes
as it reacts with iron found in hemoglobin. It is used by biologists in cellular assays for the detection of
copper
,
iron
, and
cyanides
, in addition to the detection of specific proteins by
Western Blot
.
For analysis of an area, luminol can be sprayed evenly across the area, and trace amounts of an activating oxidant will cause the luminol to emit a blue glow that can be seen in a darkened room. The glow lasts for about 30 seconds, but the effect can be documented by a long-exposure photograph. It is important that the spraying be evenly applied to avoid creating a slanted, or biased impression, such as blood traces appearing to be more concentrated in areas which received more spray. The intensity of the glow does not indicate the original amount present, but only the distribution of trace amounts of substances left in the area.
