Label-Free Detection of Dopamine Using Aptamer Enhanced Organic-Electrolyte Gated FET Sensor

Title: Label-Free Detection of Dopamine Using Aptamer Enhanced Organic-Electrolyte Gated FET Sensor Abstract: In this work we fabricated, characterized and implemented low cost, organic transistors for biosensory applications. low temperatures and atmospheric pressures fabrication using additive manufacturing steps produced sensors implemented as Aptamer-enhanced Organic Electrolyte Gated Field Effect Transistors (OEGFETs), for vital small molecules detection. OEGFET performance was characterized through transistor I-V transfer curves with different electrolytic solutions. This work is motivated by the need for accurate, low-cost, non-invasive biofluid testing devices. Label-free sensing such as OEGFETs simplifies testing and creates novel device frameworks for application to varied biomolecules to selectively, rapidly and accurately produce electrical readouts correlating sensor performance to detection limit.
