Fully Printed Low-Voltage Field-Effect Transistor Biosensor Array for One-Drop Detection of Shewanella onedensis MR‑1 Bacteria

Fast and simple bacterial detection using an in situ measurement technique is indispensable for medical diagnosis, public hygiene, and environmental monitoring. However, current bacterial detection techniques still require large measurement apparatus with complicated analysis. In this work, we propo...

Description
Summary:Fast and simple bacterial detection using an in situ measurement technique is indispensable for medical diagnosis, public hygiene, and environmental monitoring. However, current bacterial detection techniques still require large measurement apparatus with complicated analysis. In this work, we propose the use of a full printing process for the fabrication of field-effect-transistor (FET) biosensors using π-junction gold nanoparticle (AuNP) ink and semiconducting single-wall carbon nanotube (sc-SWCNT) ink, which show a low voltage (
