The single molecule level determination with a transistor (SiMoT) platform has attracted considerable attention in the recognition of various ultralow abundance biomolecules, while complicated labeling and testing processes limit its further applications. Recently, organic field-effect (OFET)-based biosensors are good candidates for constructing an advanced label-free SiMoT due to their facile fabrication process, rapid response time, low sample volume wide range detection. However,...
