Regulation of dynamic aggregation states of polymer/water interfaces and their application to bioinert materilas，2018.04 - 2021.03，Regulation of dynamic aggregation states of polymer/water interfaces and their application to bioinert materilas

For the purpose of understanding and controlling the aggregation states and thermal molecular motion in the outermost region of the polymer film, various polymers were synthesized based on precision polymerization and thin films of them were prepared. Surface and interface were characterized by various microscopy and spectroscopy techniques. As a result, it was found that the thicker and more diffused layer at the outermost interface expressed the higher bio-inert property. In addition, it was clarified that the degree of these factors could be easily tuned by using silica nano particles, and that the adhesion and extension behaviors of fibroblasts could be arbitrarily controlled.

Dynamics and Function of Polymers at Water Interface，2015.04 - 2018.03，Dynamics and Function of Polymers at Water Interface

The objective of this project is to give a better understanding of aggregation states and hierarchical molecular motion of polymer chains at the interfaces with corresponding non-solvents. The local conformation, the density profiles along the direction normal to the interface and the segmental dynamics of polymer chains were systematically studied at the interface with water, which is a typical non-solvent for conventional polymers. This was combined with the adhesion behavior of biological components onto the polymer interface, leading to a novel guideline for the design and construction of polymer devices, which contribute promisingly to life innovation.

Preparation and functionalization of water-containing solid films made from deoxyribonucleic acid，2015.04 - 2018.03，Preparation and functionalization of water-containing solid films made from deoxyribonucleic acid

Deoxyribonucleic acids (DNAs) were intermolecularly cross-linked using 2,5-hexanedione. Cross-linking points between DNAs were directly observed by atomic force microscopy. While DNA chains near cross-linking points were denatured, DNA chains not near cross-linking points maintained B-form double strands. A self-supported sheet of cross-linked DNA (DNA-c) was obtained by a simple solvent-casting method. The tensile properties of DNA-c sheets were much better than those of non-cross-linked DNA sheets due to the presence of the cross-linking portions. Wide-angle X-ray diffraction measurements revealed that the reorientation of DNA-c was remarkably restricted by the introduction of cross-linking points. Furthermore, to suppress the water evaporation which causes changing the tensile properties of the solid sheets of DNA in a short time, we used hydrated ionic liquid, CDP. The tensile properties of DNA/CDP sheets could be maintained for a time being longer than several days.
