| Outline of Final Research Achievements |
Magnetic and optical properties of uric acid crystals initiating gout were investigated for the development of a new possible diagnostics for gout. We studied the effect of magnetic fields on structure of uric acid crystals. In addition, the relation between light reflection by micro-crystals and magnetic orientation was evaluated for the realization of optical diagnostics of crystallization. As a model system, a dynamic change of the crystal structure from amorphous to plate-like crystals was exhibited. Magnetic orientation of the plate-like crystals right after applying a 500 mT magnetic field was observed. The observed distinct anisotropy of uric acid crystals is useful for the remote detection of the uric acid crystallization and its shape.
