Fluorescein
A fluorescent dye synthesised in 1871 by the German chemist Adolf von Baeyer: in ophthalmology it highlights damage to the cornea and, injected into a vein, lets doctors photograph the retinal vessels (angiography, first described in 1961). This family brings together the active ingredient, pharmacopoeial impurities and other impurities.
Did you know?Chicago plumbers used it to trace illegal discharges into the river: that is why, in the 1960s, it was the first dye the city used to turn its river green for St Patrick's Day.
