Zusammenfassung: | The present invention relates to a graphene oxide-quantum dot complex sensor for detecting an ascorbic acid having excellent sensitivity and accuracy by using a mineralizer light intensity of a graphene oxide-quantum dot complex, and a method for detecting the ascorbic acid using the same. The graphene oxide-quantum dot complex sensor of the present invention uses an oxidized graphene sheet having excellent specific surface area and electron transfer ability as a support body, thereby more accurately proposing a correlation (reproducibility) of a quantum dot extinction reaction according to the ascorbic acid concentration. The graphene oxide-quantum dot complex sensor of the present invention has excellent sensitivity and can measure the concentration of the ascorbic acid up to 568 pM. The graphene oxide-quantum dot complex sensor of the present invention is capable of simply and quickly measuring the concentration of the ascorbic acid concentration through a light emission intensity measurement in an aqueous solution state.
본 발명은 산화그래핀-양자점 복합체의 광소광도를 이용하여 감도와 정확성이 우수한 아스코빅산 검출용 산화그래핀-양자점 복합체 센서 및 이를 이용한 아스코빅산 검출 방법에 관한 것이다. 본 발명의 산화그래핀-양자점 복합체 센서는 비표면적과 전자전달능이 우수한 산화 그래핀 시트를 지지체로 사용하여 아스코빅산 농도에 따른 양자점 소광 반응의 상호관계(재현성)를 보다 정확하게 제시할 수 있다. 본 발명의 산화그래핀-양자점 복합체 센서는 감도가 우수하여 아스코빅산의 농도를 568pM까지 측정할 수 있다. 본 발명의 산화그래핀-양자점 복합체 센서는 수용액 상태에서 발광세기 측정을 통해 간단하고 빠르게 아스코빅산 농도를 측정할 수 있다. |
