摘要

本文提出了一种氨基酸修饰TiO2薄膜的超亲水pH敏感电极，并对其进行了研究，以提高培养底物中pH值的敏感响应。首先，通过正交实验研究了改性工艺因素对电极亲水性和pH敏感性的影响。利用SEM、XRD和XPS分析了化学腐蚀因素对电极形貌和组成的影响。氨基酸修饰对电极的组成有显著影响，对表面亲水性和pH敏感性有强烈影响。最后，通过对比实验发现氨基酸修饰的TiO2电极在敏感响应上有明显的提高。

Enhanced Amino Functionalization TiO₂ Electrodes for pH Detection of Culture Substrates In Situ

A superhydrophilic pH-sensitive electrode with amino acid-modified TiO2 thin film is proposed in this work and studied to improve the sensitive response of pH values in culture substrates. First, the influence of modification process factors on the hydrophilicity and pH sensitive of the electrodes was studied with orthogonal experiment. Then, SEM, XRD, and XPS were used to investigate the influence of the chemical etching factors on the morphology and composition of the fabricated electrodes. Amino acid modification was found to have a significant influence the component of the electrode, which strongly affected the surface hydrophilicity and pH sensitive. Finally, it was found that amino acid-modified TiO2 electrode showed a marked improvement in sensitive response through comparative experiments.
