Abstract:
In the last few years, healthcare monitoring and diagnostic tools such as point-of-need (PON) and point-of-care (POC) witnessed a blooming demand from healthcare providers as well as the general population. The widespread of wearable technology and the ongoing shift in healthcare paradigms made society very receptive to such tools. On the other hand, solid-state devices featuring organic conducting polymers and nanomaterials are expected to offer an attractive alternative to conventional electrochemical methods such as potentiometry and amperometry. Among these devices, organic electrochemical devices are promising technologies due to their low power consumption, facile fabrication, and ion-to-electron transduction. In a nutshell, the objective of this doctoral thesis is to explore new thick film organic electrochemical devices on paper substrate, by means of conducting polymer inks and nanomaterials. The devices are based on two solid-state technologies: the organic electrochemical transistor (OECT) and the chemiresistor, and utilize facile fabrication and functionalization procedures, which enables the detection of relevant biomolecules.
