Outline of Final Research Achievements

Improvement of Surface Plasmon Resonance (SPR) based biosensors that can detect biological interaction on a metal surface by controlling the surface design was attempted. Glycopolymer was used as a molecular recognition material to capture target molecule on the biosensor surface. Change in detection function of the SPR biosensor by controlling the polymer length, glycan type, and glycan incorporation ratio was evaluated. Biosensing system for exhaustive analysis of interaction between glycopolymers and biomolecules were also constructed.

Academic Significance and Societal Importance of the Research Achievements

本研究では、これまで糖鎖による認識が深く知られていない生体分子に対する糖鎖高分子の結合について調べた。糖鎖高分子がターゲットとしてきた生体分子の多くは糖鎖認識性タンパク質のレクチンであったが、レクチン以外のタンパク質や酵素などに対する糖鎖による認識の可能性を見出すことができた。今後、糖鎖高分子を用いたバイオセンサーによって検出可能な生体分子のレパートリーが増えることが期待される。
