Abstract
Fabrication of a low-cost and miniaturized solid-contact thread-based ion sensing electrode (ISE) that is suitable for point-of-care applications is described. The fabrication process is simple and scalable. Different types of threads and a variety of different conductive ion-to-electron transducer inks can be used to fabricate the thread-based ISEs with Nernstian responses. Multiple thread-based sensors can be easily bundled with the reference electrode to fabricate a customized sensor for multiplexed ion-sensing in small sample volumes. The thread-based electrodes can be used in both single-use and reusable fashion. The thread-based multiplexed ion-sensor is used for detection of a wide array of ions in many different types of aqueous solutions.
