Abstract
The application discloses a preparation method and application of a cucurbit[7]uril functionalized carbon paper electrode. The electrode comprises the following steps: taking carbon paper as a substrate, introducing beta-mercaptoethylamine modified gold nanoparticles loaded cucurbit[7]uril on the surface of the substrate after carboxylation. The high-sensitivity detection of creatinine is realized by detecting the impedance change generated after the recognition of creatinine by cucurbit[7]uril. The electrode has the advantages of high sensitivity, fast detection time and simple operation, and provides a new method for creatinine determination, and is suitable for popularization and use.
