In this work, a liquid crystal (LC)-based aptasensor for okadaic acid (OA) detection was developed with a novel aptamer mechanism for enhancing the optical signals of LCs. In this molecular strategy, a short linker aptamer was utilized to immobilize on the sensing platform to form a double-stranded...
