Outline of Final Research Achievements

Analytical methods utilizing small spaces, as represented by micro and extended-nano fluidic devices, have been developed. We have developed thermal lensing microscope (TLM) and photothermal optical phase shift (POPS) detection to detect non-fluorescent molecules in small spaces with high sensitivity. However, the UV-excitation POPS detection has some problems such as heat dissipation in the extended-nano channel and insufficient reduction of optical background due to interference, which hinders measurements with high sensitivity as TLM. In this study, we developed an extended-nano fluidic device with an integrated thermo-optic layer to recover the sensitivity loss due to the thermal diffusion and a background-free POPS detector to achieve ultrahigh sensitivity.

Academic Significance and Societal Importance of the Research Achievements

単一細胞中のタンパク質は少ないもので10コピーから存在するとされている。このような極めて少ない分子を計測する際、バルク空間に希釈してしまうとその濃度を決定することは困難となるから、極微小空間に閉じ込めたまま測定した方が有利である。当研究室では既に拡張ナノ流路を用いたクロマトグラフィーを初めとする単一細胞分析プロセスの開発に成功しており、本研究で開発したPOPSはその有効な検出法となる。また、フッ化カルシウムを熱光学層としてナノ流路の底面に集積化するために開発したプロセスは、今後他の電極、触媒、メタマテリアル等にも応用可能であり、ナノ流体化学プロセスの更なる発展に貢献すると考えられる。
