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.
