| titleOfInvention | A kind of method for detecting L semicystinol concentrations using graphene quantum dot and nanogold |
| abstract | The invention discloses a kind of method for detecting L semicystinol concentrations using graphene quantum dot and nanogold, including：Preparation includes graphene quantum dot and the detection solution of nanogold；Establish the fluorescence intensity and the linear relationship of L semicystinol concentrations of detection solution；Into the solution to be measured of L cysteines, addition detects solution, detects the fluorescence intensity of solution to be measured, the linear relationship established according to step 2, determines the concentration of L cysteines in solution to be measured.The present invention is using graphene quantum dot as probe, graphene quantum dot fluorescence is quenched using nanogold, and L cysteines are combined the characteristic for recovering graphene quantum dot fluorescence with nanogold, cysteine is detected, detection process is simple and convenient, high sensitivity, test limit are low, and the rapid sensitive detection of L cysteines in biased sample can be achieved, and method disclosed by the invention can reach 1.5 × 10 to the test limit of L cysteines ‑8 mol/L。 |
