  • The design and chemical synthesis of multifunctional nanomaterials have been providing potential applications in biomedical fields such as molecular imaging and drug delivery. Recently, bio-derived and/or synthetic nanostructured materials capable of modulating the immune system have been also issues of interest in immunology-related nanomedicine fields. In this talk, the recent research results on the development of nanostructured materials for enhanced immunity would be presented. I will introduce the chemical strategy for the combination of nanostructured materials and bioactive compounds to improve both anti-cancer immunity and vaccine delivery efficiency.

  • Recently a system for nondestructive measurement of seedling plants in real time has been attracting attention as an essential element in fields such as the "smart farm". This study reports the simultaneous measurement of anthocyanin accumulations in leaf tissues in a large number of bok choy, using a hyperspectral imaging system. To measure many seedlings simultaneously, an existing hyperspectral imaging system is modified. In this paper, a total of 96 seedlings are measured: 24 each of 4 cultivars. Using the hyperspectral data-acquisition system, 12 seedlings can be analyzed simultaneously within 3 minutes. The hyperspectral imaging technology proposed in this paper is shown to provide an analytic system comparable to destructive chemical analysis. This hyperspectral imaging technology can be applied to a high-throughput plant-phenotyping system, owing to its capability of measuring a large number of specimens at the same time.
