| Outline of Final Research Achievements |
Artificial blood is free from the blood-type and infection disease, and stored in long period. In our research we attempted the preparation of a hemoglobin-like blood-substitute based on myoglobin which has been scarcely developed as the oxygen carrier. The main results of our research are as follows. First, we could reduce the high oxygen affinity of myoglobin using the skeletal modification of iron porphyrin. Second, the influence of metal substitution of central iron in porphyrin to cobalt was found very effective to lower the oxygen affinity of myoglobin. Third, we have developed the method to make complex of the artificial myoglobins with the organic nanotubes. In the series of experiments, we found the critical problems to be improved, and pointed out the method to improve the technical problems. These critical points include the solvent pH, ionic strength, and temperature of the incubation to prepare the sealed myoglobin.
