Purpose of Research

It is an essential task to develop the results of nanotechnology / materials, which is one of the four priority fields of National Basic Plans of Science and Technology to open up new areas of integration in various fields and an aim for the next super smart society. Research representatives have generated magnetic nanoparticles of several nanometers using a unique manufacturing method and have reported on their quantum mechanical physical phenomena in detail. In addition, while attempting to apply this concept to the biotechnology field in recent years, we made the important discovery that this particle has an ionization support function (Achievement 2). Through the continued advancement of this research, it may eventually be possible to analyze a wide range of molecules ranging from small molecules to macromolecules through mass spectrometry with high resolution. We expect that this will allow for unprecedented analysis of specimens. Furthermore, since the particles are nanosized, it has been suggested that high-resolution molecular imaging is possible without losing visual information (Anal. Chem. 2008).

 In this research, we propose to treat cancer using magnetic nanoparticles while also advancing the application of this method in the field of pathological diagnosis. Furthermore, by applying superconductor devices, we will also develop analytical devices through process control by combining technologies such as nanomaterial processing and cell signal amplification. By fusing the element technologies of participating members, we will contribute to the development of medical technology based on fundamental physics and engineering, as well as life sciences.
