Description
Summary:Electrolyte-gated organic field-effect transistors (EGOFETs) provide a versatile platform for ultrasensitive, fast, and reliable detection of biological molecules in liquid media using low-cost bioelectronic sensors. The key functional layers of the EGOFETs include the semiconductor and biorecognition layers based on conjugated organic molecules, which must meet high requirements for the operational stability in various electrolytes when detecting analytes. In this work, EGOFETs based on 2,6-dioctyltetrathienoacene as the semiconductor material were fabricated by the doctor blade method compatible with printing technologies. We also report on EGOFETs with the biorecognition layer based on a biotin-containing derivative of [1]benzothieno[3,2- b ]benzothiophene, which was applied by the Langmuir—Schaeffer method. The possibility of stable operation of the fabricated EGOFETs in various electrolytes and their sensor responses to the electrolyte pH value and streptavidin are demonstrated.
