Outline of Final Research Achievements

We constructed nanoscale optical logic circuits as a core structure of a fluorescence nano-multiplexer. Some circuits by connecting Forster resonance energy transfer (FRET) gates were designed, and they were fabricated by self-assembly of DNA with fluorescence molecules. The behavior was demonstrated by measuring responses to static and time series inputs.
We also investigated a method for synthesizing diverse fluorescence spectra based on arrangements of multiple fluorescence molecules. Experimental results on 24 arrangements demonstrated applicability of the method for multiplex molecular imaging.

Academic Significance and Societal Importance of the Research Achievements

一段のみのFRETを用いてナノ光論理回路を構成できることを示した最初の実施例であり,簡便な実装法や低エネルギー損失を実現する方法を示していることの意義は大きい.また,本手法は,単一種類の出力光信号で複数種類の対象分子の情報を送出するための方式を示している.これにより,より多くの種類の分子の空間分布や時間発展をまとめて捉えることが可能となり,多重分子イメージングの発展に寄与することが期待される.
