Organic Semiconductors in Organic Thin-Film Transistor-Based Chemical and Biological Sensors

Electrolyte-gated organic field-effect transistors have emerged in the field of biosensors over the last five years, due to their attractive simplicity and high sensitivity to interfacial changes, both on the gate/electrolyte and semiconductor/electrolyte interfaces, where a target-specific bioreceptor can be immobilized. This article reviews the recent literature concerning biosensing with such transistors, gives clues to understanding the basic principles under which electrolyte-gated organic field-effect transistors work, and details the transduction mechanisms that were investigated to convert a receptor/target association into a change in drain current.

“…Another issue that must be addressed is their high subthreshold swing, typically of several hundreds of millivolts, which impede their sensitivity. A strategy may be to switch from The electrolyte used can be polymers [19][20][21][22], ionic liquids [23][24][25] or ionic gels [16,[26][27][28][29]. Aqueous liquid electrolytes were also reported.…”

“…Consequently, the current flow through the channel can be changed and controlled by the gate voltage. This feature allows OFETs to operate as a type of amplifier or a transducer through converting a voltage or potential signal into a current response [128]. More details of the principles, understanding the structural, and electrical properties of materials used to construct OFETs have been reviewed elsewhere [128,129].…”

Integration of additive manufacturing and inkjet printed electronics: a potential route to parts with embedded multifunctionality

-Additive manufacturing, an umbrella term for a number of different manufacturing techniques, has attracted increasing interest recently for a number of reasons, such as the facile customisation of parts, reduced time to manufacture from initial design, and possibilities in distributed manufacturing and structural electronics. Inkjet printing is an additive manufacturing technique that is readily integrated with other manufacturing processes, eminently scalable and used extensively in printed electronics. It therefore presents itself as a good candidate for integration with other additive manufacturing techniques to enable the creation of parts with embedded electronics in a timely and cost effective manner. This review introduces some of the fundamental principles of inkjet printing; such as droplet generation, deposition, phase change and post-deposition processing. Particular focus is given to materials most relevant to incorporating structural electronics and how post-processing of these materials has been able to maintain compatibility with temperature sensitive substrates. Specific obstacles likely to be encountered in such an integration and potential strategies to address them will also be discussed.

“…Therefore, it is essential to develop and investigate potential bio-degradable, bio-compatible, bioresorbable, or even metabolizable devices, which serve as the components of various electronic and photonic products. Environmentally-friendly electronics based on the natural materials such as polypeptide [4], albumen [5], and nucleic bases [6] are potential approaches that promise to meet these needs.…”

Abstract:Recently, biological materials such as DNA molecules, proteins, and albumen have been extensively investigated for various applications, as they are environmentally friendly and exhibit novel optical and electronic properties. Especially, over the last decades, DNA-lipid complex have been frequently reported as components of optical electronic devices. In this mini-review, the physicochemical performance of DNA-lipid complex is introduced, and then the related research progress in electronic devices such as organic thin film transistors and other optical-electrical devices are discussed. Finally, the challenges and prospects of other possible applications are also presented.
