■タイトル
　Evaporation induced self-assembly of megamolecular polysaccharide through planar and linear air-LC interfaces

■論文概要
　Deriving inspiration and biomimicking the structural hierarchy of biopolymers, has led researchers to explore a number of fields especially evaporation based self-assembly of particles. One of these is the use of air-liquid crystalline (LC) interface for organization of polymer LC domains into highly ordered films. We have studied the evaporation induced self-assembly behavior of a polysaccharide solution through planar as well as linear evaporative fronts. The planar front leads to deposition of layered, in-plane oriented film. Whereas, a linear front leads to nucleation followed by a vertically deposited membrane formed by the splitting of the interface. The meniscus curve was analyzed theoretically so as to clarify the rationale behind splitting of the interface in a linear front followed by vertical deposition. This splitted interface actually is capable of providing approximately twice the surface area as compared to the normal one. We foresee that optimizing drying conditions and concentration, other polymeric solutions can also split meniscus and form highly oriented vertical deposition.

■論文タイトル
　Establishment of versatile magnetic separation of organelles using magnetic-plasmonic hybrid nanoparticles

■論文概要
　In order to investigate proteins and lipids on certain cellular organelles, centrifugation techniques have been widely used. Unfortunately, however, heterologous organelles which are barely different in size and mass cannot be effectively separated by these centrifugation techniques. Magnetic separation has attracted attention in this regard because it can separate the target organelle selectively. Moreover, it can isolate organelles rapidly and mildly compared to conventional centrifugation-based separation techniques.
　Although several types of organelles such as endosomes, exosomes and mitochondria have been magnetically separated, the current magnetic separation technique has limitations in terms of imaging and versatility because iron oxide-based beads are mostly used as probes. In this study, we developed magnetic-plasmonic hybrid Ag@FeCo@Ag core@shell@shell nanoparticles (NPs) which are capable of plasmonic bioimaging as well as magnetic separation. To demonstrate the separation capability using the NPs, autophagosome was selected as a target organelle. The NPs were introduced into COS1 cells by transfection. Plasmonic imaging revealed the NPs were successfully incorporated in autophagosomes. Finally, the autophagosomes were separated by the help of autoMACS Pro Separator (Miltenyi Biotec). Western blot confirmed that autophagosomes were successfully isolated.

■論文タイトル
　Design of Magnetic-Plasmonic Ternary Metallic Nanoparticles

■論文概要
　Magnetic-plasmonic multimetallic nanoparticles (NPs) which incorporate magnetic elements with plasmonic metals have attracted much attention as next-generation bioprobes simultaneously enabling plasmonic bioimaging and magnetic manipulation. Unfortunately, however, integration of Fe with Au (or Ag) is challenging due to the large immiscibility in binary Au-Fe and Ag-Fe systems. Even though much effort has been made to synthesize AuFe alloy or FePt@Au core@shell magnetic-plasmonic systems, most of the literature conflict each other in terms of structure-property relation, and therefore, there still remains several challenges regarding the chemical synthesis of homogeneous alloy NPs without any phase segregation, while in the case of core@shell NPs, inability to coat magnetic core with the plasmonic shell, suppressing the formation of pure Au or Ag NPs is a major challenge.
On the other hand, there are a number of studies which show that, Au or Ag has been included in fcc FePt, as a dopant to lower the annealing temperature required for the transformation from chemically-disordered fcc phase to chemically-ordered L10 phase. On the basis of these previous studies, we designed a synthetic strategy where Pt can be used as mediating element for combining Fe with Au or Ag, to form AuFePt or AgFePt ternary alloy NPs. The work demonstrates new avenues for the creation of multimetallic magnetic-plasmonic NPs and gives new insight into control over the resulting magnetic and plasmonic characteristics.

　I am very privileged to receive prestigious CSJ Student Presentation Award 2017. I am earnestly grateful to the organizing committee and jury members for recognition of my work because I believe that every other nominee for this award was equally capable of winning it. Besides, by attending this conference I got an opportunity to learn various aspects of cutting edge research presented by diversified peer research groups, which was definitely a phenomenal experience and helped me to improvise and broaden my knowledge in the materials science. Since I have successfully completed my doctoral studies in March 2017, therefore this award becomes more special for me as an acceptance of my research work by the greater global scientific community.
Having been a doctoral student of JAIST, I can safely say that I took correct decisions a few years ago to pursue my studies in this institute. The world-class scientific environment, research facilities, comfortable life and monetary supports granted by JAIST could only be made this success possible, therefore I would like to express my sincere gratitude towards JAIST. I would like to say that this is not just my individual effort, in fact, I would like to make a special mention of my supervisor Professor Shinya Maenosono, who has been my mentor throughout my masters and doctoral studies and stay in Japan. It is him, who saw the capabilities in me and nurtured my passion for pursuing doctoral studies in the materials science. Everyone has the dream to get such a teacher, fortunately, I got mine. Once again my heartfelt thanks to him. At the same, I would also like to take this opportunity to thank Assistant Professor Derrick Mott for his persistent guidance and constant motivation. It is important to mention and thanks, Mr. Koichi Higashimine here, for his valuable effort to help us regarding few of our most crucial measurements, without which our research work cannot be done. Special cheers to all the Maenosono lab members, this award is definitely an effort by all of us together and will be shared equally among all of us. Finally, I like to thanks my parents and family members for always encouraging me to continue the hard work and morally supporting throughout my good and bad times. I would like to dedicate this award to my parents and all others.

■タイトル
　Directional Control of Diffusion and Swelling in Hydrogels Prepared from Cyanobacterial Exopolysaccharide

■論文概要
　With the goal of constructing novel biomaterials, we have studied the LC hetero-polysaccharide, sacran extracted from the extracellular matrix of the freshwater cyanobacteria, Aphanothece sacrum. It demonstrated a high potential for significant water retention and had a liquid crystal nature at a critical concentration of ~ 0.3 %. In the present work, by investigating the swelling ratio and swelling kinetics three-dimensionally, the effects of the thickness of precursor films with LC orientation on diffusion are discussed. The thinner films swelled to a larger extent than their thicker counterparts. The dried films were analyzed using TEM and SEM techniques at nano- and sub-micron scale, respectively. It was observed that sacran fibers arrange in nano-platelets during the drying process and form oriented structure via nano layering and sub-micron layering. Due to the presence of this layered structure, we have successfully controlled the diffusion parallel to the planar direction and swelling in the lateral direction. We believe that these hydrogels will be useful for dynamic control in biomedical applications such as engineering replacement tissues, reconstructive surgeries, and the design of sustained drug delivery devices.

■タイトル
　Syntheses of renewable high-performance polybenzimidazoles and their applications for polymeric ionic conductor

■論文概要
　We have prepared imidazole based polymer 2, 5-polybenzimidazole (2, 5-PBI) from 3-amino-4-hydroxybenzoic acid (3, 4-AHBA) which has been successfully synthesized from soil-bacteria Streptomyces sp. This polymer shows very high thermal resistance (Td10 at 630°C) and mechanical strength (Strain 100 MPa and Young's modulus at 9.5 GPa) which can be useful for industrial purposes. As we have used bio-derived monomer for the preparation of the polymer so we don't need to worry about limited resource problem which is a major concern for fossil-fuel based polymers.
　
　Presence of substitutable imidazole (-NH) proton is an important factor for the modification of the polybenzimidazole structure and in our case after modification, Li-ions are free and conductive. They are showing increased Li-ion transference number on addition of plasticizing agent BMImTFSi, they are keeping the stability of the structure even after several charge-discharges cycles because of high thermal and chemical stability. With these results we are thinking of to use this kind of bio-derived polymers in Li-ion batteries.
