Outline of Research at the Start

近年、高機能な細孔電気抵抗法の技術により、ウイルスや細胞外小胞といった生体由来の微粒子を1つ1つ数えることが可能となっている。一方で観測された生体微粒子が何であるかを特定することは難しいため、検出したい生体微粒子を選択的に捕捉可能な受容体を有するナノスケールの材料や表面の開発を行う。これによる次世代型の疾患検出システム等の創出を目指す。

Outline of Final Research Achievements

Resistive pulse sensing (RPS) is an analytical technique to measure particles individually. Therefore, it can assume to be used for early diagnosis such as infection of pathogenic virus and bacteria, and tumor derived particles from a small amount of samples. On the other hand, RPS cannot measure a biological information to detect the measured particles. In this study, preparation of a functional nano-bio interface for an application to detect biological particle analysis was investigated.

Academic Significance and Societal Importance of the Research Achievements

本研究では機能性界面により、汚れが付着しにくい表面の作製や、ウイルスを捕捉する表面を作製することができた。この機能性界面を用いることでポア計測の際に孔が詰まるのを防ぐことができたほか、ウイルスがポア表面に捉えられる様子を計測することに成功した。また、がん由来の生体分子検出に有効な機能性界面の創製も実現した。これらの成果は、新しいウイルスの迅速診断やがんの早期検出に結びつく有望な技術となりうる。
