| titleOfInvention | Based on NSCQDs/Bi2S3Photoelectrochemical sensor and preparation method thereof |
| abstract | The invention relates to a method based on NSCQDs/Bi 2 S 3 The photoelectrochemical sensor and the preparation and the application thereof, and Bi 2 S 3 The nano-rod is an optical active material, and NSCQDs are synthesized by a PDDA electrostatic adsorption hydrothermal method; then theCarboxyl groups on the surfaces of NSCQDs are activated by EDC and NHS, and Ab is modified on the surfaces of the electrodes through amidation reaction. In the presence of AFP, an Ab-AFP immune complex is formed on the surface of an electrode through antigen-antibody recognition, so that the steric hindrance of the surface of the electrode is increased, the transmission of an electron sacrificial agent Ascorbic Acid (AA) to the surface of the electrode is hindered, and the change of a sensor photocurrent signal is caused. And detecting the AFP concentration according to the relation between the AFP concentration and the sensor photocurrent. The photoelectrochemical sensor provided by the invention has good selectivity, repeatability and stability. The invention has the advantages of simple ATP detection operation, low cost, high efficiency and high sensitivity, lower detection limit and wider detection range, and has important significance for clinical and biological analysis of protein. |
