摘要: A water-soluble luminescent compound having repeating units of the formula: ##STR1## The product, which is a polymer having repeating units comprising diazo-linked luminol and hydroxyindole, is referred to as diazoluminomelanin (DALM), since one of the precursors to this product, 3-amino-L-tyrosine (3AT) is closely related to the biological substrates which are converted into melanin.Also provided is a method for preparing DALM which comprises reacting 3AT with an alkali metal nitrite, and reacting the resulting diazonium salt with luminol.DALM can be used for chemiluminescent immunoassays for biological and chemical agents; in radiofrequency and ionizing radiation dosimeters; and for RNA/DNA hybridization assays for viruses and genetic detection.
