Embodiment 1
[0021] Example 1: Application of Ultrasensitive Photoelectrochemical Sensor in Detection of Mucin 1 (MUC1)
[0022] (1) Deposit a layer of Au nanoparticles on the ITO electrode: first, wash the ITO conductive electrode in acetone, ethanol, and secondary water for 10 min, and insert the cleaned electrode into the deposition solution containing 1% chloroauric acid. Au nanoparticles were deposited on the surface of the ITO conductive electrode at a deposition potential of -0.2 V and a deposition time of 60 s using the potential stripping analysis method. After the deposition was completed, the electrode surface was cleaned with secondary water and dried naturally at room temperature. , to obtain ITO / Au electrodes;
[0023] (2) Using the in-situ growth method to obtain TiO grown on the surface of the ITO / Au electrode in step (1) 2 Particles: insert the ITO / Au electrode into a 25 mL beaker containing 15 mL of ammonium fluorotitanate and boric acid mixture, the concentration of amm...
