“…Solution‐processed poly(3‐hexyl thiophene) P3HT‐based OFET baring silk fibroin as gating material has also been reported by Shi et al The silk fibroin film was found to be resistant upon the exposure to the solvent of the semiconductor, thus allowing the deposition of P3HT via spin‐coating. Low threshold voltage (−0.77 V) and a mobility of 0.21 cm 2 V −1 s −1 , which is comparable to the highest mobility reported for regioregular P3HT using inorganic dielectrics, were obtained at low operating voltages (−3 V).…”

This review aims to provide an update on the development involving dielectric/organic semiconductor (OSC) interfaces for the realization of biofunctional organic field-effect transistors (OFETs). Specific focus is given on biointerfaces and recent technological approaches where biological materials serve as interlayers in back-gated OFETs for biosensing applications. Initially, to better understand the effects produced by the presence of biomolecules deposited at the dielectric/OSC interfacial region, the tuning of the dielectric surface properties by means of self-assembled monolayers is discussed. Afterward, emphasis is given to the modification of solid-state dielectric surfaces, in particular inorganic dielectrics, with biological molecules such as peptides and proteins. Special attention is paid on how the presence of an interlayer of biomolecules and bioreceptors underneath the OSC impacts on the charge transport and sensing performance of the device. Moreover, naturally occurring materials, such as carbohydrates and DNA, used directly as bulk gating materials in OFETs are reviewed. The role of metal contact/OSC interface in the overall performance of OFET-based sensors is also discussed.

“…For example, organic thin-film transistors (OTFTs) have been prepared with biopolymers because these devices can be fabricated with large-scale manufacturing techniques, such as screen printing, spin-coating, gravure printing, and others. Also, as biopolymers are contained in abundant resources, the fabricated devices are generally of low-cost [1][2][3][4][5]. These fascinating characteristics of OTFTs make them potential candidates for moveable memory devices [6], active matrix displays [7], radio frequency identification tags [8], and biochemical sensors [9].…”

In recent years, biopolymers are highly desired for their application in optic electronic devices, because of their unique structure and fantastic characteristics. In this work, a non-volatile memory (NVM) device based on the bio thin-film transistor (TFT) was fabricated through applying a new RNA-CTMA (cetyltrimethylammonium) complex as a gate dielectric. The physicochemical performance, including UV, CD spectral, thermal stability, surface roughness, and microstructure, has been investigated systematically. The RNA-CTMA complex film exhibits strong absorption with a well-defined absorption peak around 260 nm, the RMS roughness is~2.1 nm, and displayed excellent thermal stability, up to 240 • C. In addition, the RNA-CTMA complex-based memory device shows good electric performance, with a large memory window up to 52 V. This demonstrates that the RNA-CTMA complex is a promising candidate for low cost, low-temperature processes, and as an environmentally friendly electronic device.

human life. [1][2][3] To achieve such a dream, choosing natural biomaterials such as nucleic acids, [4][5][6] peptides, [7] proteins, [8,9] and polysaccharides [10] as the substitutes of fossil source-based synthetic chemicals is a promising way. Correspondingly, micro/ nanoscale fabrication on natural biomaterials receives great of importance, [11] and a spatially definable property with high precision to exactly position biomaterials on a surface is highly desirable [12][13][14][15][16][17][18] toward biodegradable and biocompatible green electronic, [19][20][21][22] optical, [23][24][25][26][27][28][29] sensor, [30] energy, [31] and environmental devices. [32] Typical examples down this road include silk fibroin, [12][13][14] polysaccharides, [10] and DNA origami-mediated lithography. [5] These approaches are part of great efforts to develop "green" lithographic processing in semiconductor industry that is eligible to lessen the exposure of workers and environment toward noxious chemical and reduce waste. [13] The adoption of these strategies allows the replacement of organic solvent with water to cast and develop a resist, accompanied with the exclusion of environmentally harmful components from material processing and fabrication. However, so far the lithographic processes based on existing natural biomaterials are difficult to be exploited in scale-up industrial application, because their limited quantities, high material, and processing cost as well as small deposition area impede the practical engineering of these biomaterials. [9] Moreover, the less-controlled variation on polymorph and polydispersity of biomaterials often influences the repeatability of results. [33] Recently, our group reported the use of phase-transited lysozyme nanofilm as the resist for photolithography and electron-beam lithography (EBL), with the cost being decreased and practical applicability being potentially demonstrated. [17] Continuous efforts along this way further require much cheaper material and simpler fabrication process for large-scale industrial uses. In this respect, we pay attention to egg white due to the following reasons. First, egg white is a very common natural biomaterial just taken from egg as our daily food, which makes it has great natural abundance with a low cost. Second, in contrast to other natural competitors usually requiring strict demands on the purity, polydispersity, and polymorph stability, egg white is a combination of multiple functional nutrients, [34] which could be directly utilized without further purification and Complex lithographic steps and the use of toxic chemicals in these processes are in conflict with a sustainable human society. Development of new inexpensive and green resist, simple alternative procedures, and nontoxic solvents is the key to move recyclable micro/nanofabrication from laboratory level to industrial application in large scale. Herein, precise control on protein fragmentation/aggregation upon photo/electron irradiation is conceived into egg white-based green resist...
