| titleOfInvention | Method for quantitatively determining mixed component CdS/ZnS quantum dots in plant root epidermal tissue |
| abstract | The invention provides a method for quantitatively determining mixed component CdS/ZnS quantum dots in plant root epidermal tissues. The method comprises the following steps: cleaning and drying plant roots, and coating a mixed component CdS/ZnS quantum dot solution with different surface ligands; carrying out laser-induced nanosecond time-resolved fluorescence spectrum detection on the epidermis of the plant root to obtain a fluorescence spectrum; and scanning the fluorescence spectra of different quantum dots to obtain derivative fluorescence spectra, and establishing standard curves of the fluorescence intensity and the concentration of different quantum dots in the epidermis of the plant root. According to the method, the nanosecond time-resolved fluorescence spectroscopy and the constant matrix derivative synchronous fluorescence spectroscopy are combined for use, so that the interference of the autofluorescence signal of the plant root surface can be effectively eliminated, the in-situ quantitative analysis of the mixed component quantum dots adsorbed by the plant root epidermis can be realized, the method is high in accuracy and stability, and the recovery rate and the selectivity are excellent; meanwhile, the method of the invention does not cause damage to plants and can carry out plant living body detection. |
