On May 4-8, 1987, a NATO Advanced Research Workshop on the Analytical Uses of Immobilized Biological Compounds was held in Florence, Italy. The Director of the Workshop was Professor George G. Guilbault of the University of New Orleans, and the Co-Director was Professor Marco Mascini of the University of Florence It vas the purpose of this meeting to assemble scientists from all NATO Countries with an interest in immobilized biological compounds. to discuss - methods of immobilization - properties of immobilized compounds - enzyme electrodes and biosensors - optical devices utilizing immobilized enzymes - microbial sensors and clinical uses of immobilized enzymes - flow injection analysis using enzymes - immobilized biological compounds in chemical defense detection - pharmaceutical analysis - uses in industrial analysis - enzyme reactors - air pollution detectors - immunosensors - medical uses and applications - solid state and FET sensors Goals to be achieved by the conference were - to permit an exchange of views and experience in all these areas - to review and critically assess the state-of-the-art in these fields - to set guidelines for future research and establish collaborative projects between scientists in NATO laboratories in the above areas. Thirty-seven lectures were given by 36 speakers in all of the above areas.
