| titleOfInvention | Method for detecting nitrite ions based on polymer carbon dot fluorescence colorimetry |
| abstract | The invention belongs to the field of nanotechnology, and discloses preparation of a polymer carbon dot and a detection method of the polymer carbon dot applied to nitrite ion colorimetric fluorescence. When nitrite ions with different concentrations exist in a buffer system containing a certain amount of polymer carbon dots, the absorption peak at 610nm of an absorption spectrum is obviously reduced, and the absorption peak at 380nm is gradually enhanced; the fluorescence spectrum gradually decreases the intensity of the fluorescence emission peak at 625nm with the increase of nitrite ions. Therefore, according to the change of the fluorescence spectrum and the absorption spectrum of the polymer carbon dots in the system, the high-sensitivity and high-selectivity detection of nitrite ions is realized through the analysis of a fluorescence colorimetric multi-output signal. Further, detection of nitrite ions in complex systems such as urine is also achieved. The polymer-based carbon dot fluorescent colorimetric probe is a new development of the original analysis method, and is expected to be used for analyzing and detecting nitrite ions in complex systems such as food, environment and the like. |
