Outline of Final Research Achievements

Magneto-optical effects have not been utilized in analytical chemistry so far, because their signal is small, generally. We established a fundamental technique to measure various magneto-optical effects with a damped oscillating magnetic field (DOMF). We tried to observe several kinds of magneto-optical effect. Most notably, it was demonstrated that the physical rotation of a magnetic nanoparticle (MNP) could be observed from the magnetically induced linear dichroism (MLD) waveform. It was possible to measure the MLD signals of MNP in polymer solution or inner water of liposome. Therefore, this technique can be utilized to investigate the local environment around the MNP.

Academic Significance and Societal Importance of the Research Achievements

減衰振動パルス磁石は安価かつ小型であるため、パルス磁石や強力交流磁石のような電源のためのスペースが不要である。コイル形状の工夫によっては様々な光学系との組み合わせが可能であり、例えば顕微系にも適用できる。またMNPの回転運動観測は、磁気ナノ粒子イメージングや磁気温熱療法のようなMNPを応用した医療技術に基礎的な知見を提供できるほか、ゲル網目間や微小流路内のような局所環境の粘度測定に利用可能と期待される。
