Outline of Final Research Achievements |
The purpose of this research is to develop highly sensitive luminescence sensor for detecting extremely low concentration of radioactive strontium 90. In order to achieve the objective, "self-immolative chemical reaction system" was devised. The system consists of three components: (I) a site that recognizes strontium ion, releases a mediator (Ⅱ) a site that amplifies the released mediator (Ⅲ) a site that chemiluminesis with the amplified mediator, High-intensity luminescence is detected by continuously reacting. We focused on the most important reaction process (Ⅱ) to (Ⅲ) by using fluoride ion (F ion) as a mediator. By using the optimal mixing ratio of the F ion excitation agent and the chemiluminescent substance which was found out, detection by luminescence was achieved even in a trace amount (0.20 nmol) of F ion.
