From non-electroactive to electroactive species: highly selective and sensitive detection based on a dual-template molecularly imprinted polymer electrochemical sensor.

A new strategy for sensitive detection using a dual-template molecularly imprinted based electrochemical sensor was developed using thionine as an electrochemical probe. A single-signal for the non-electroactive template and a dual-signal for the electroactive template in the selective and sensitive detection have been achieved on the prepared sensor.
