Early Efforts – BKA• Gros, Spring, and Deinet report in 1995on the unsuccessful effort to chemicallymodify the cyanoacrylate monomer tomake it fluorescent/colored• Attempts to reproduce work of SJ Yongfrom the Australian National University in1966• Reaction of anthracene with the ethylcyanoacrylate monomer to produce anethyl ester adduct• The adduct typically decomposed d ratherthan produce a fluorescent CA reagentU.S. Department ofHomeland SecurityUnited StatesSecret ServiceRobert Ramotowski 26 July 201216
Recent Efforts – Israel National Police• Attempts were made to chemicallymodify the CA monomer• Similar to BKA effort - they synthesizedDiels-Alder adducts of anthracene andethyl cyanoacrylatey• Anthracene-cyanoacrylic acid is thenformed and then subjected to a retro-Diels-Alder reaction to liberate afluorescent CA monomer• The anthracene sublimed too fast andended up coating the entire exhibitwithout developing latent printsU.S. Department ofHomeland SecurityUnited StatesSecret ServiceRobert Ramotowski 26 July 201217
