| titleOfInvention | Preparation method of fluorescence sensor for detecting aristolochic acid A |
| abstract | The invention discloses a preparation method of a fluorescence sensor for detecting aristolochic acid A, which comprises the steps of firstly synthesizing Carbon Quantum Dots (CQDs), then synthesizing ovalbumin-stable gold nanoclusters (OVA @ AuNCs), respectively dissolving the carbon quantum dots and the ovalbumin-stable gold nanoclusters with ultrapure water, and then uniformly mixing to obtain the fluorescence sensor for detecting aristolochic acid A; during detection, the carbon quantum dots are taken as a main body, the OVA @ AuNCs are used for enhancing the fluorescence of the carbon quantum dots, and then the fluorescence of CQDs-OVA @ AuNCs is quenched by adding aristolochic acid A; the method comprises the following steps of (1) quantitatively detecting aristolochic acid A by using CQDs-OVA @ AuNCs as a fluorescence sensing platform in a fluorescence quenching manner; the method overcomes the defects of the existing detection technology of aristolochic acid A that the method is too complex, the detection speed is slow and the identification of aristolochic acid A is low; the method is simple, convenient, rapid, high in controllability and high in efficiency, is suitable for industrial production, and has wide market application prospect. |
