폴리다이아세틸렌 베시클을 이용한 킬레이트제의 색전이 검출
Colorimetric Detection of Chelating Agents Using Polydiacetylene Vesicles
박무경, 김경우, 안동준, 오민규
본 연구에서는 폴리다이아세틸렌(polydiacetylene, PDA) 베시클을 이용하여 여러 가지 킬레이트제 (chelating agent)를 쉽게 검출할 수 있는 센서 시스템을 개발하였다. 다른 센서들과 비교하여 PDA기반 센서는 많은 장점이 있다. 첫째로, 형광물질의 부착이 필요 없는 무표지 검출(label-free detection)이 가능하여 실험 절차가 간단하고 빠르다. 둘째로, PDA는 청색에서 외부 자극에 의해 적색으로 변화하는 색전이를 일으키므로 육안으로 쉽게 검출을 확인할 수 있었다. 끝으로, 특정 파장에서의 colorimetric response를 측정하여 각각의 킬레이트제의 농도에 따른 정량검출도 가능하다. 본 연구에서는 5가지 종류의 킬레이트제, 즉 EDTA, EGTA, NTA, DCTA, DTPA를 PDA 베시클과 반응시켰으며, 이중에서 EDTA, DCTA는 특히 강한 반응으로 PDA의 색전이를 유도함을 알 수 있었다. 본 연구를 통하여 PDA 베시클을 사용하여 어떠한 기계나 동력을 사용하지 않고 색전이를 이용하여 킬레이트를 성공적으로 검출할 수 있음을 보여주었다.
In this research, we developed a sensor system which can easily detect several chelating agents using polydiacetylene(PDA) vesicles. In comparison to other sensors, PDA based sensor has several advantages. First, detection method is much simpler and faster because it does not require any labeling step in the experiment procedure. Second, significant color-transition from blue to red based upon external stimulus allows us the detection by naked eyes. Finally, it is also possible to perform quantitative analysis of the concentration of the chelating agent by measuring the colorimetric response. In this paper, five types of chelating agents were used, including EDTA, EGTA, NTA, DCTA and DTPA. Among them, EDTA and DCTA triggered especially strong color-transition. In conclusion, this study has led to a successful development of a color transition-based PDA sensor system for easy and rapid detection of chelating agents.
