title: Homogeneous fluorescent immunoassay.
abstract: A fluorescent immunoassay based on the correlation of fluctuations in particle number measures the amount of tagged species bound to micrometer-sized beads and is insensitive to background fluorescence. Without separation steps, a competitive assay can resolve I nanogram of gentamicin per milliliter from a total sample volume of only 10 microliters.
