Outline of Final Research Achievements

To optimize the preparation technique of drug delivery system particles for biofilm infections, we developed sample pretreatment technique using an ionic liquid and scanning transmission electron microscopy-cathodoluminescence. Especially, CL imaging and CL analysis of polymeric particles in the biofilm was successfully performed by attaching the fluorescent materials. These developed techniques could be effective to design of polymeric particles for treating biofilm infection diseases.

Academic Significance and Societal Importance of the Research Achievements

上記の「研究成果の概要」に記載した新規の評価法を組み込むことで、有効なバイオフィルム感染症治療薬が開発できれば、治療の短期化による医療費の抑制や多剤耐性菌の発現リスク低減などが期待される。また、本研究成果は歯周病が引き起こしうる白内障や糖尿病、心筋梗塞などの疾病予防にも繋がるため社会的波及効果は大きい。また、学術的観点から、従来の試料作製法では形態維持が難しいとされる微小器官の構造解析が可能となり、微生物のみでなく動植物の生体機構解明及び未知なる機能探索にも大きく寄与するものと考えられる。
