摘要:

血清中组氨酸(His)水平异常变化可能与多种疾病相关,因此检测His具有重要的临床意义。光电化学(PEC)传感具有灵敏度高、操作简单、价格低廉和易于微型化等优点,是一种有潜力的临床检测手段。由于缺乏合适的识别机制,到目前为止PEC传感器用于His检测仍未见报道。本研究提出以小分子探针作为识别单元构建光电化学传感界面的方法,通过探针与His之间的特异性反应提高传感器的选择性。因此,构建的光电化学传感器具有较好的选择性、稳定性和重现性,可用于生物样品中His的定量检测。

Abstract:

Abnormal change of histidine (His) level in serum may be associated with various diseases, making the detection of His clinically significant. Photoelectrochemical (PEC) sensing has the potential to be a promising clinical detection method due to its high sensitivity, simple operation, low cost, and ease of miniaturization. However, to date, PEC sensing for His detection has not been reported due to the lack of suitable recognition mechanisms. In this study, we construct a PEC sensing interface using a small molecule probe as the recognition unit, and the selectivity of the sensor is improved through a specific reaction between the probe and His. The developed (PEC) sensor has good selectivity, stability, and reproducibility, which can be used for the quantitative detection of His in biological samples.

Key words: Photoelectrochemical sensing, Histidine, Small molecular probes
