In
the 1950s the NIH's Dr. Robert Bowman developed
a sensitive instrument-called the spectrophotofluorometer,
or "SPF"-that allowed scientists to
use fluorescence
as a way to identify and measure tiny amounts
of substances in the body. This scientific breakthrough,
invented almost half a century ago, is still used
today in AIDS research and the Human Genome Project.
