我们研制了一种法拉第笼型适配传感器,用于电致发光和DPV对VP的超灵敏双模检测。得益于精心设计的信号单元和法拉第笼式传感器的构造方式,从两个方面大大提高了检测灵敏度。一是信号单元中的二维Ru-MOF具有更大的表面积,可以携带更多的信号标签。另一种是二维Ru-MOF延伸电极表面,使信号单元上的所有信号标签都在OHP范围内并具有电化学活性。在这种情况下,VP的检测灵敏度可提高到1.7CFU mL−1。此外,ECL和DPV获得的两组数据可以相互比较和验证,有效地提高了检测的可靠性。此外,适体的使用保证了检测的选择性和特异性。事实上,这种方法不仅适用于VP的检测,而且只需改变相应的适体并优化实验条件,即可用于检测其他大体积的生物靶标。为电化学方法检测大体积生物靶标提供了新的思路和生物传感平台。
We have developed a Faraday cage-type aptasensor for ultrasensitive dual-mode detection of VP by ECL and DPV. Benefitted from the well-designed signal unit and Faraday cage-type sensor construction way, the detection sensitivity is greatly enhanced from two aspects. One is that the two-dimensional Ru-MOF in the signal unit has a larger surface area and can carry more signal tags. The other is the two-dimensional Ru-MOF extends the electrode surface, causing all signal tags on the signal unit to be within the OHP range and have electrochemical activity. In this case, the detection sensitivity of VP is increased up to 1.7 CFU mL−1. In addition, two sets of data obtained by ECL and DPV could be used to compare and confirm each other, improving the detection reliability effectively. Besides, the use of aptamers ensures the selectivity and specificity of detection. In fact, this method is not only suitable for detecting VP, but also can be used to detect other large-volume biological targets only by changing the corresponding aptamer and optimizing experimental conditions. It provides a novel idea and biosensing platform for the detection of large-volume biological targets by electrochemical methods.
